'''Rabbits''' are small [[mammal]]s in the [[family (biology)|family]] [[Leporidae]] (which also includes the [[hare]]s), which is in the [[order (biology)|order]] [[Lagomorpha]] (which also includes [[pika]]s). The [[European rabbit]], ''Oryctolagus cuniculus'' is the ancestor of the world's hundreds of [[List of rabbit breeds|breeds]]<ref name="DAD-IS 2017">{{cite web|title=Data export|url=http://www.fao.org/dad-is/dataexport/en/|website=DAD-IS (Domestic Animal Diversity Information System)|publisher=FAO (Food and Agriculture Organization of the United Nations)|access-date=30 March 2018|date=21 November 2017}}</ref> of [[domestic rabbit]]. ''Sylvilagus'' includes 13 wild rabbit species, among them the seven types of [[cottontail rabbit|cottontail]]. The European rabbit, which has been introduced on every continent except [[Antarctica]], is familiar throughout the world as a wild prey animal, a domesticated form of livestock and a pet. With its widespread effect on ecologies and cultures, in many areas of the world, the rabbit is a part of daily life – as food, clothing, a companion, and a source of artistic inspiration.

Rabbits are a [[paraphyletic]] grouping, and do not constitute a [[clade]], as [[hares]] are nested within the [[Leporidae]] clade and are not included in rabbits.

Although once considered [[rodent]]s, lagomorphs diverged earlier and have a number of traits rodents lack, including two extra [[incisor]]s.

==Terminology and etymology==
A male rabbit is called a ''buck''; a female is called a ''doe''.  An older term for an adult rabbit used until the [[18th century]] is ''coney'' (derived ultimately from the [[Latin]] {{lang|la|cuniculus}}), while ''rabbit'' once referred only to the young animals.<ref name="Coney etymology">{{cite web|title=''coney''|url=https://www.etymonline.com/search?q=coney|website=Online Etymology Dictionary|access-date=2 March 2018}}</ref> Another term for a young rabbit is ''bunny'', though this term is often applied informally (particularly by children) to rabbits generally, especially domestic ones. More recently, the term ''kit'' or ''kitten'' has been used to refer to a young rabbit.

A group of rabbits is known as a ''colony'' or ''nest'' (or, occasionally, a ''warren'', though this more commonly refers to where the rabbits live).<ref>{{cite web | url=http://www.ojohaven.com/collectives | title=The Collective Noun Page | access-date=2008-01-30 | url-status=live | archive-url=https://web.archive.org/web/20080201105020/http://www.ojohaven.com/collectives/ | archive-date=1 February 2008 | df=dmy-all }}</ref> A group of baby rabbits produced from a single mating is referred to as a ''litter''<ref>{{cite web|url=https://www.merckvetmanual.com/all-other-pets/rabbits/breeding-and-reproduction-of-rabbits|title=Breeding and Reproduction of Rabbits|last=McClure |first=Diane|year=2018|website=Merck Veterinary Manual|archive-url=https://web.archive.org/web/20180106120335/https://www.merckvetmanual.com/all-other-pets/rabbits/breeding-and-reproduction-of-rabbits|archive-date=6 January 2018|url-status=live|access-date=5 January 2018|df=dmy-all}}</ref> and a group of domestic rabbits living together is sometimes called a ''herd''.<ref name="usgs">{{cite web|url=http://www.npwrc.usgs.gov/about/faqs/animals/names.htm|title=Common Questions: What Do You Call a Group of...?|work=archived copy of Animal Congregations, or What Do You Call a Group of.....?|publisher=U.S. Geological Survey Northern Prairie Wildlife Research Center|archive-url=https://web.archive.org/web/20150320071411/http://www.npwrc.usgs.gov/about/faqs/animals/names.htm|archive-date=20 March 2015|url-status=dead|access-date=26 February 2018}}</ref>

==Taxonomy==
{{see also|List of leporids}}

Rabbits and hares were formerly classified in the order [[Rodent]]ia (rodent) until 1912, when they were moved into a new order, [[Lagomorpha]] (which also includes [[pika]]s). Below are some of the genera and species of the rabbit.

The term ''rabbit'' is typically used for all Leporidae species, excluding the genus ''Lepus''. Members of that genus are instead known as ''hares'' or ''jackrabbits''.

''Lepus'' species are [[precocial]], born relatively mature and mobile with hair and good vision, while rabbit species are [[altricial]], born hairless and blind. Hares and some rabbits live a relatively solitary life in a simple nest above the ground, while other rabbits live in social groups in [[burrow]]s, which are grouped together to form [[Warren (burrow)|warrens]]. Hares are generally larger than rabbits, with ears that are more elongated and hind legs that are larger and longer. Descendants of the [[European rabbit]] are commonly bred as livestock and kept as pets, whereas no hares have been [[domesticated]]; the breed called the [[Belgian hare]] is actually a [[domestic rabbit]] which has been selectively bred to resemble a hare.

===Domestication===
{{Main|Domestic rabbit}}

Rabbits have long been domesticated. The European rabbit has been widely kept as livestock, starting in [[ancient Rome]]. [[Selective breeding]], which began in the Middle Ages, has generated a [[List of rabbit breeds|wide variety of rabbit breeds]], of which many (since the early 19th century) are also kept as pets.<ref name="Irving-PeaseFrantz2018">{{cite journal|last1=Irving-Pease|first1=Evan K.|last2=Frantz|first2=Laurent A.F.|last3=Sykes|first3=Naomi|last4=Callou|first4=Cécile|last5=Larson|first5=Greger|title=Rabbits and the Specious Origins of Domestication|journal=Trends in Ecology & Evolution|volume=33|issue=3|pages=149–152|year=2018|issn=0169-5347|doi=10.1016/j.tree.2017.12.009|pmid=29454669|s2cid=3380288 |url=http://qmro.qmul.ac.uk/xmlui/handle/123456789/34474}}</ref> Some [[Strain (biology)|strains]] of rabbit have been bred specifically as [[Animal testing|research subjects]].

As livestock, rabbits are bred for their meat and [[Rabbit hair|fur]]. The earliest breeds were important sources of meat, and so became larger than wild rabbits, but domestic rabbits in modern times range in size from [[Dwarf rabbit|dwarf]] to [[Flemish Giant rabbit|giant]]. Rabbit fur, prized for its softness, can be found in a broad range of [[coat (animal)|coat]] colors and patterns, as well as lengths. The [[Angora rabbit]] breed, for example, was developed for its long, silky fur, which is often [[Hand spinning|hand-spun]] into yarn. Other domestic rabbit breeds have been developed primarily for the commercial [[fur trade]], including the [[Rex rabbit|Rex]], which has a short [[plush]] coat.

==Biology==
[[File:Set of wax models showing development of the rabbit heart, twentieth century (24226156252).jpg|thumb|left|Wax models showing the development of the rabbit heart]]

===Evolution===
Because the rabbit's [[epiglottis]] is engaged over the soft palate except when swallowing, the rabbit is an [[obligate nasal breathing|obligate nasal breather]]. Rabbits have two sets of incisor teeth, one behind the other. This way they can be distinguished from [[rodent]]s, with which they are often confused.<ref>{{cite book |last=Brown |first=Louise |title=How to Care for Your Rabbit |publisher=Kingdom Books |year=2001 |isbn=978-1-85279-167-4 |page=6 }}</ref>  Another difference is that for rabbits, all of their teeth continue to grow, where as for most rodents, only their incisors continue to grow.  [[Carl Linnaeus]] originally grouped rabbits and rodents under the class [[Glires]]; later, they were separated as the scientific consensus is that many of their similarities were a result of [[convergent evolution]]. Recent DNA analysis and the discovery of a common ancestor has supported the view that they share a common lineage, so rabbits and rodents are now often grouped together in the superorder Glires.<ref name="Quesenberry 2012">Katherine Quesenberry & James W. Carpenter, ''Ferrets, Rabbits, and Rodents: Clinical Medicine and Surgery'' (3rd ed. 2012).</ref>

===Morphology===
[[File:Cmglee Horniman rabbit skin skeleton.jpg|thumb|left|Skeleton of the rabbit]]
Since speed and agility are a rabbit's main defenses against predators (including the swift fox), rabbits have large hind leg bones and well-developed musculature. Though [[plantigrade]] at rest, rabbits are on their toes while running, assuming a more [[digitigrade]] posture. Rabbits use their strong claws for digging and (along with their teeth) for defense.<ref>{{cite journal |last1=d'Ovidio |first1=Dario |last2=Pierantoni |first2=Ludovica |last3=Noviello |first3=Emilio |last4=Pirrone |first4=Federica |title=Sex differences in human-directed social behavior in pet rabbits |journal=Journal of Veterinary Behavior |date=September 2016 |volume=15 |pages=37–42 |doi=10.1016/j.jveb.2016.08.072 }}</ref> Each front foot has four toes plus a [[dewclaw]].

[[File:Wild black Oryctologus cuniculus.jpg|thumb|upright|[[Melanism|Melanistic]] coloring{{pb}}<small>''Oryctologus cuniculus''{{pb}}European rabbit (wild)</small>]]
Most wild rabbits (especially [[#Differences from hares|compared to hares]]) have relatively full, egg-shaped bodies. The soft coat of the wild rabbit is [[Agouti (coloration)|agouti]] in coloration (or, rarely, [[melanism|melanistic]]), which aids in [[camouflage]]. The tail of the rabbit (with the exception of the [[Cottontail rabbit|cottontail species]]) is dark on top and white below. Cottontails have white on the top of their tails.<ref name="Encyclopædia Britannica">{{cite encyclopedia |title=rabbit |encyclopedia=[[Encyclopædia Britannica]] |publisher=[[Encyclopædia Britannica, Inc.]] |location=Chicago |edition=Standard |year=2007 }}</ref>

As a result of the position of the eyes in its skull, the rabbit has a field of vision that encompasses nearly 360 degrees, with just a small blind spot at the bridge of the nose.<ref>{{cite web |url=http://www.bio.miami.edu/hare/vision.html?1 |title=What do Rabbits See? |access-date=2013-08-09 |url-status=live |archive-url=https://web.archive.org/web/20150923185831/http://www.bio.miami.edu/hare/vision.html?1 |archive-date=23 September 2015 |df=dmy-all }}</ref>

===Hind limb elements===
[[File:Rabbit hind limb skeleton.jpg|thumb|left|A specimen of the skeletal articulations of rabbit's hind limbs in the [[Pacific Lutheran University]] natural history collection]]
The anatomy of rabbits' hind limbs is structurally similar to that of other land mammals and contributes to their specialized form of locomotion. The bones of the hind limbs consist of long bones (the femur, tibia, fibula, and phalanges) as well as short bones (the tarsals). These bones are created through [[endochondral ossification]] during development. Like most land mammals, the round head of the femur articulates with the acetabulum of the os coxae. The femur articulates with the tibia, but not the fibula, which is fused to the tibia. The tibia and fibula articulate with the tarsals of the pes, commonly called the foot. The hind limbs of the rabbit are longer than the front limbs. This allows them to produce their hopping form of locomotion. Longer hind limbs are more capable of producing faster speeds. Hares, which have longer legs than [[cottontail rabbit]]s, are able to move considerably faster.<ref>{{Cite book|url=https://archive.org/details/practicalanatom00bensgoog|page=[https://archive.org/details/practicalanatom00bensgoog/page/n5 1]|quote=rabbit skeletal anatomy.|title=Practical anatomy of the rabbit|last=Bensley|first=Benjamin Arthur|date=1910|publisher=The University Press}}</ref> Rabbits stay just on their toes when moving; this is called [[digitigrade]] locomotion. The hind feet have four long toes that allow for this and are webbed to prevent them from spreading when hopping.<ref>{{Cite news|url=https://www.merckvetmanual.com/all-other-pets/rabbits/description-and-physical-characteristics-of-rabbits#v34404688|title=Description and Physical Characteristics of Rabbits – All Other Pets – Merck Veterinary Manual|work=Merck Veterinary Manual|access-date=2018-05-11}}</ref> Rabbits do not have paw pads on their feet like most other animals that use digitigrade locomotion. Instead, they have coarse compressed hair that offers protection.<ref>{{cite web|url=http://www.exoticpetvet.net/smanimal/rabanatomy.html|title=Rabbit Anatomy|last=D.A.B.V.P.|first=Margaret A. Wissman, D.V.M.|website=exoticpetvet.net|access-date=2018-05-11}}</ref>

====Musculature====
[[File:Lateral view of rabbit hind limb.jpg|thumb|The rabbit's hind limb (lateral view) includes muscles involved in the quadriceps and hamstrings.]]

Rabbits have muscled hind legs that allow for maximum force, maneuverability, and acceleration that is divided into three main parts: foot, thigh, and leg. The hind limbs of a rabbit are an exaggerated feature. They are much longer than the forelimbs, providing more force. Rabbits run on their toes to gain the optimal stride during locomotion. The force put out by the hind limbs is contributed by both the structural anatomy of the fusion tibia and fibula, and muscular features.<ref>{{Cite book |last1=Susan |first1=Lumpkin |last2=Seidensticker |first2=John |date=2011 |title=Rabbits: the animal answer guide |publisher=Johns Hopkins University Press |isbn=978-1-4214-0126-3|location=Baltimore|oclc=794700391}}</ref>

Bone formation and removal, from a cellular standpoint, is directly correlated to hind limb muscles. Action pressure from muscles creates force that is then distributed through the skeletal structures. Rabbits that generate less force, putting less stress on bones are more prone to osteoporosis due to bone [[rarefaction]].<ref>{{cite journal |last1=Geiser |first1=Max |last2=Trueta |first2=Joseph |title=Muscle action, bone rarefaction and bone formation |journal=The Journal of Bone and Joint Surgery. British Volume |date=May 1958 |volume=40-B |issue=2 |pages=282–311 |doi=10.1302/0301-620X.40B2.282 |pmid=13539115 |doi-access=free }}</ref> In rabbits, the more fibers in a muscle, the more resistant to fatigue. For example, [[hare]]s have a greater resistance to fatigue than [[Cottontail rabbit|cottontails]]. The muscles of rabbit's hind limbs can be classified into four main categories: [[hamstring]]s, [[Quadriceps femoris muscle|quadriceps]], [[dorsiflexors]], or [[plantar flexors]]. The quadriceps muscles are in charge of force production when jumping. Complementing these muscles are the hamstrings, which aid in short bursts of action. These muscles play off of one another in the same way as the plantar flexors and dorsiflexors, contributing to the generation and actions associated with force.<ref>{{cite journal |last1=Lieber |first1=Richard L. |last2=Blevins |first2=Field T. |title=Skeletal muscle architecture of the rabbit hindlimb: Functional implications of muscle design |journal=Journal of Morphology |date=January 1989 |volume=199 |issue=1 |pages=93–101 |doi=10.1002/jmor.1051990108 |pmid=2921772 |s2cid=25344889 }}</ref>

===Ears===
[[File:Anatomy and physiology of animals The ear.jpg|thumb|Anatomy of mammalian ear]]
[[File:Holland Lop Ears UpDown.png|thumb|A [[Holland Lop]] resting with one ear up and one ear down. Some rabbits can adjust their ears to hear distant sounds.]]
Within the order of [[Lagomorpha|lagomorphs]], the ears are used to detect and avoid predators. In the family [[Leporidae]], the ears are typically longer than they are wide. For example, in [[Black-tailed jackrabbit|black-tailed jackrabbits]], their long ears cover a greater surface area relative to their body size, which allows them to detect predators from far away. In contrast with cottontail rabbits, their ears are smaller and shorter, requiring that predators be closer before they can detect them and flee.

Evolution has favored rabbits with shorter ears, so the larger surface area does not cause them to lose heat in more temperate regions. The opposite can be seen in rabbits that live in hotter climates; possessing longer ears with a larger surface area helps with dispersion of heat. Since sound travels less well in arid as opposed to cooler air, longer ears may aid the organism in detecting predators sooner rather than later in warmer temperatures.<ref name="Hall">{{Cite book|title=The Mammals of North America|last=Hall|first=E.

The ear muscles also aid in maintaining balance and movement when fleeing predators.<ref>{{Cite journal|last=Meyer|first=D.

====Outer ear====
The [[auricle (anatomy)|auricle]], also known as the pinna, is a rabbit's outer ear.<ref name="Capello 2006">{{Cite journal|last=Capello|first=Vittorio|date=2006|title=Lateral Ear Canal Resection and Ablation in Pet Rabbits|url=http://www.ivis.org/proceedings/navc/2006/SAE/617.pdf?LA=1|journal=The North American Veterinary Conference|volume=20|pages=1711–1713}}</ref> The rabbit's pinnae represent a fair part of the body surface area.

====Middle ear====
The middle ear, separated by the outer eardrum in the back of the rabbit's skull, contains three bones: the hammer, anvil, and stirrup, collectively called [[ossicles]], which act to decrease sound before it hits the inner ear; in general, the ossicles act as a barrier to the inner ear for sound energy.<ref name="Parsons 2018" />

====Inner ear====
Inner ear fluid, called [[endolymph]], receives the sound energy. After receiving the energy. The inner ear comprises two parts: the [[cochlea]] that uses sound waves from the ossicles, and the [[vestibular apparatus]] that manages the rabbit's position in regard to movement. Within the cochlea a [[basilar membrane]] contains sensory hair structures that send nerve signals to the brain, allowing it to recognize different sound frequencies. Within the vestibular apparatus three semicircular canals help detect [[angular motion]].<ref name="Parsons 2018" />

===Dewlaps===
[[File:Palomino rabbit with kit.jpg|thumb|A palomino rabbit displaying her dewlap beside a month-old kit]]
A [[dewlap]] is a longitudinal flap of [[skin]] or similar flesh that hangs beneath the [[lower jaw]] or [[neck]]. It is a [[secondary sex characteristic]] in rabbits, caused by the presence of female sex hormones. They develop with [[puberty]]. A female rabbit who has been [[neutering|neutered]] before reaching sexual maturity will not develop a dewlap, and even if a doe is neutered after developing a dewlap, the dewlap will gradually disappear over several months.

===Respiratory system===
[[File:Dissected Rabbit Lungs.jpg|thumb|upright|Ventral view of dissected rabbit lungs with key structures labeled]]

The rabbit's nasal cavity lies dorsal to the oral cavity, and the two compartments are separated by the hard and soft palate.<ref name="Johnson-Delaney 2011" /> The nasal cavity itself is separated into a left and right side by a cartilage barrier, and it is covered in fine hairs that trap dust before it can enter the [[respiratory tract]].<ref name="Johnson-Delaney 2011" /><ref name="Smith 2019" />{{page needed|date=October 2019}} As the rabbit breathes, air flows in through the nostrils along the alar folds.

The trachea then splits into a left and right bronchus, which meet the lungs at a structure called the [[Root of the lung|hilum]]. From there, the bronchi split into progressively more narrow and numerous branches. The bronchi branch into bronchioles, into respiratory bronchioles, and ultimately terminate at the alveolar ducts. The branching that is typically found in rabbit lungs is a clear example of monopodial branching, in which smaller branches divide out laterally from a larger central branch.<ref name="Autifi 2015" />

The structure of the rabbit's nasal and oral cavities necessitates breathing through the nose. This is due to the fact that the epiglottis is fixed to the backmost portion of the soft palate.<ref name="Jekl 2012" /> Within the oral cavity, a layer of tissue sits over the opening of the glottis, which blocks airflow from the oral cavity to the trachea.<ref name="Johnson-Delaney 2011">{{Cite journal|last1=Johnson-Delaney|first1=Cathy A.|last2=Orosz|first2=Susan E.|year=2011|title=Rabbit Respiratory System: Clinical Anatomy, Physiology and Disease|journal=Veterinary Clinics of North America: Exotic Animal Practice|language=en|volume=14|issue=2|pages=257–266|doi=10.1016/j.cvex.2011.03.002|pmid=21601814}}</ref> The epiglottis functions to prevent the rabbit from aspirating on its food.

===Digestion===

{{Main|Cecotrope}}

Easily digestible food is processed in the [[gastrointestinal tract]] and expelled as regular feces. But in order to get nutrients out of hard to digest fiber, rabbits ferment fiber in the cecum (in the gastrointestinal tract) and then expel the contents as [[cecotrope]]s, which are reingested ([[cecotrope|cecotrophy]]). The cecotropes are then absorbed in the small intestine to utilize the nutrients.<ref name="Quesenberry 2012"/><ref name="dummies 1">{{cite web |url=http://www.dummies.com/how-to/content/exploring-a-rabbits-unique-digestive-system.html |title=Exploring a Rabbit's Unique Digestive System |work=Rabbits for Dummies |access-date=2013-08-14}}</ref>

===Reproduction===
[[File:Male rabbit reproduction system.png|thumb|Diagram of the male rabbit reproductive system with main components labeled]]
The adult male reproductive system forms the same as most mammals with the seminiferous tubular compartment containing the [[Sertoli cell]]s and an adluminal compartment that contains the [[Leydig cell]]s.<ref name="Foote 2000">{{Cite journal|last1=Foote|first1=Robert H|last2=Carney|first2=Edward W|year=2000|title=The rabbit as a model for reproductive and developmental toxicity studies|journal=Reproductive Toxicology|volume=14|issue=6|pages=477–493|doi=10.1016/s0890-6238(<span class="ltr">00</span>)00101-5|pmid=11099874|issn=0890-6238}}</ref> The Leydig cells produce [[testosterone]], which maintains libido<ref name="Foote 2000" /> and creates secondary sex characteristics such as the [[genital tubercle]] and [[penis]]. The Sertoli cells triggers the production of [[Anti-Müllerian hormone|Anti-Müllerian duct hormone]], which absorbs the Müllerian duct. In an adult male rabbit, the [[Penile sheath|sheath of the penis]] is cylinder-like and can be extruded as early as two months of age.<ref name="LafeberVet repro basics">{{cite web|url=https://lafeber.com/vet/rabbit-reproduction-basics/|title=Rabbit Reproduction Basics|date=2014-05-05|website=LafeberVet|language=en-US|access-date=2019-05-06}}</ref> The scrotal sacs lay lateral to the penis and contain [[Epididymis|epididymal]] fat pads which protect the testes.

The average female rabbit becomes sexually mature at three to eight months of age and can conceive at any time of the year for the duration of her life. Egg and sperm production can begin to decline after three years.<ref name="Foote 2000" /> During mating, the male rabbit will insert his penis into the female from behind, make rapid pelvic thrusts until [[ejaculation]], and throw himself backwards off the female. [[Copulation (zoology)|Copulation]] lasts only 20–40 seconds.<ref>{{cite web|url=http://florida4h.org/projects/rabbits/MarketRabbits/Activity8_Mating4.html|title=Understanding the Mating Process for Breeding Rabbits|website=florida4h.org|access-date=2019-04-12}}</ref>

The rabbit [[gestation]] period is short and ranges from 28 to 36 days with an average period of 31 days. A longer gestation period will generally yield a smaller litter while shorter gestation periods will give birth to a larger litter. The size of a single litter can range from four to 12 kits allowing a female to deliver up to 60 new kits a year. After birth, the female can become pregnant again as early as the next day.<ref name="LafeberVet repro basics" />

After mating, in some species, hormonal changes will cause the doe to begin to dig a burrow for her nest about a week before giving birth. Between three days and a few hours before giving birth another series of hormonal changes will cause her to prepare the nest structure. The doe will first gather grass for a structure, and an elevation in [[prolactin]] shortly before birth will cause her fur to shed that the doe will then use to line the nest, providing insulation for the newborn kits.<ref name="stress">{{cite journal |last1=Benedek |first1=I |last2=Altbӓcker |first2=V |last3=Molnár |first3=T |date=2021 |title=Stress reactivity near birth affects nest building timing and offspring number and survival in the European rabbit (''Oryctolagus cuniculus''). |journal=PLOS ONE |volume=16 |issue=1 |pages=e0246258 |bibcode=2021PLoSO..1646258B |doi=10.1371/journal.pone.0246258 |pmc=7845978 |pmid=33513198 |doi-access=free}}</ref>

Rabbits have been a source of environmental problems when introduced into the wild by humans. As a result of their appetites, and the rate at which they breed, [[feral]] rabbit depredation can be problematic for agriculture. Gassing ([[fumigation]] of warrens),<ref>{{cite web |last1=Department of Primary Industries and Regional Development |last2=Agriculture and Food Division |last3=Pest and Disease Information Service (PaDIS) |title=Rabbit control: fumigation |url=https://www.agric.wa.gov.au/baits-poisons/rabbit-control-fumigation |website=agric.wa.gov.au |publisher=Government of Western Australia |access-date=25 September 2021 |language=en}}</ref> [[Rabbit-proof fence|barriers (fences)]], shooting, snaring, and [[Rabbiting#Ferreting|ferreting]] have been used to control rabbit populations, but the most effective measures are diseases such as [[myxomatosis]] (''myxo'' or ''mixi'', colloquially) and [[Rabbit haemorrhagic disease virus|calicivirus]]. In Europe, where rabbits are farmed on a large scale, they are protected against myxomatosis and calicivirus with a [[genetically modified virus]]. The virus was developed in Spain. If it were to make its way into wild populations, it could create a population boom, as those diseases are the most serious threats to rabbit survival.

Rabbits are often posited by scholars as symbols of [[fertility]] and spring. The [[Easter Bunny]] is a figure from Lutheran German folklore that then spread to America and later other parts of the world and is similar to [[Santa Claus]]. The rabbits' role as a prey animal with few defenses evokes vulnerability and innocence and in folklore and modern children's stories, rabbits often appear as sympathetic characters, able to connect easily with youth of all kinds (for example, the [[Velveteen Rabbit]] or [[Thumper (Disney)|Thumper]] in ''[[Bambi]]'').{{cn|date=May 2024}}

With its reputation as a prolific breeder, the rabbit juxtaposes [[Human sexuality|sexuality]] with innocence, as in the [[Playboy Bunny]]. The rabbit is also known for its speed, agility, and endurance, symbolized (for example) by the marketing icons the [[Energizer Bunny]] and the [[Duracell Bunny]].{{cn|date=May 2024}}

===Folklore===
{{Main|List of fictional hares and rabbits}}

The rabbit often appears in folklore as the [[trickster]] [[archetype]] as he uses his cunning to outwit his enemies.

* In [[Aztec mythology]], a pantheon of four hundred rabbit gods known as [[Centzon Totochtin]], led by [[Ometochtli]] or Two Rabbit, represented fertility, parties, and drunkenness.
* In Central Africa, the common hare (''Kalulu''), is "inevitably described" as a trickster figure.<ref>Brian Morris, ''The Power of Animals: An Ethnography'', p. 177 (2000).</ref>
* In [[Chinese folklore]], rabbits accompany [[Chang'e (mythology)|Chang'e]] on the Moon. In the [[Chinese New Year]], the [[Rabbit (zodiac)|zodiacal rabbit]] is one of the twelve celestial animals in the [[Chinese zodiac]]. The [[Chinese zodiac#Chinese zodiac in other countries|Vietnamese zodiac]] includes a [[Cat (zodiac)|zodiacal cat]] in place of the rabbit. The most common explanation is that the ancient Vietnamese word for "rabbit" ''(mao)'' sounds like the Chinese word for "cat" ([[wiktionary:卯|卯]], ''mao)''.<ref>{{cite web |title=Year of the Cat OR Year of the Rabbit? |url=http://www.nwasianweekly.com/2011/02/year-of-the-cat-or-year-of-the-rabbit/ |website=nwasianweekly.com |access-date=27 February 2018 |date=2011-02-03}}</ref>
* In [[Culture of Japan|Japanese tradition]], rabbits [[Moon rabbit|live on the Moon]] where they make [[mochi]], the popular snack of mashed [[Glutinous rice|sticky rice]]. This comes from interpreting the pattern of dark patches on the moon as a rabbit standing on tiptoes on the left pounding on an [[Usu (Mortar)|usu]], a Japanese mortar.
* In [[Jewish folklore]], rabbits (shfanim, שפנים) are associated with cowardice, a usage still current in contemporary Israeli spoken [[Hebrew language|Hebrew]] (similar to the English colloquial use of "chicken" to denote cowardice).
* In [[Korean mythology]], as in Japanese, rabbits live on the moon making rice cakes ("[[Tteok]]" in Korean).
* In [[Anishinaabe traditional beliefs]], held by the [[Ojibwe]] and some other [[Indigenous peoples of the Americas|Native American]] peoples, [[Nanabozho]], or Great Rabbit, is an important deity related to the creation of the world.
* A Vietnamese myth portrays the rabbit as innocent and youthful. The gods of the myth are shown to be hunting and killing rabbits to show off their power.
* [[Buddhism]], Christianity, and Judaism have associations with an ancient circular motif called the ''[[Three hares|three rabbits]]'' (or "three hares"). Its meaning ranges from "peace and tranquility", to purity or the [[Holy Trinity]], to [[Kabbalah#Levels of the soul|Kabbalistic levels of the soul]] or to the [[Jewish diaspora]].  The tripartite symbol also appears in [[Three hares#Other uses and related designs|heraldry]] and even [[Three hares|tattoos]].

The rabbit as [[trickster]] is a part of American popular culture, as [[Br'er Rabbit]] (from African-American folktales and, later, [[Walt Disney Animation Studios|Disney animation]]) and [[Bugs Bunny]] (the [[cartoon]] character from [[Warner Bros.#Warner's cartoons|Warner Bros.]]), for example.

Anthropomorphized rabbits have appeared in film and literature, in ''[[Alice's Adventures in Wonderland]]'' (the [[White Rabbit]] and the [[March Hare]] characters), in ''[[List of Watership Down characters|Watership Down]]'' (including the [[Watership Down (film)|film]] and [[Watership Down (1999 TV series)|television]] adaptations), in ''[[Rabbit Hill]]'' (by [[Robert Lawson (author)|Robert Lawson]]), and in the ''[[Peter Rabbit]]'' stories (by [[Beatrix Potter]]).  In the 1920s, ''[[Oswald the Lucky Rabbit]]'' was a popular cartoon character.

A [[rabbit's foot]] may be carried as an [[amulet]], believed to bring protection and [[luck|good luck]]. This belief is found in many parts of the world, with the earliest use being recorded in Europe c. 600&nbsp;BC.<ref name="Ellis">{{cite book|last1=Ellis|first1=Bill|title=Lucifer Ascending: The Occult in Folklore and Popular Culture|date=1 January 2004|publisher=University Press of Kentucky|isbn=978-0-8131-2289-2}}</ref>

On the [[Isle of Portland]] in Dorset, UK, the rabbit is said to be unlucky, and speaking the creature's name can cause upset among older island residents. This is thought to date back to early times in the local quarrying industry, where, to save space, extracted stones that were not fit for sale were set aside in what became tall, unstable walls. The local rabbits' tendency to burrow there would weaken the walls, and their collapse would result in injuries or even death. In the local culture to this day, the rabbit (when he has to be referred to) may instead be called a "long ears" or "underground mutton" so as not to risk bringing a downfall upon oneself.<ref>{{cite web |title=Wallace and Gromit spook island |url=http://news.bbc.co.uk/1/hi/england/dorset/4318710.stm |website=BBC News |access-date=25 August 2022 |date=7 October 2005}}</ref>

In other parts of Britain and in North America, "[[Rabbit rabbit rabbit]]" is one variant of an [[Apotropaic magic|apotropaic]] or [[talisman]]ic superstition that involves saying or repeating the word "rabbit" (or "rabbits" or "white rabbits" or some combination thereof) out loud upon waking on the first day of each month, because doing so is believed to ensure good fortune for the duration of that month.<ref>{{Cite web |last=Mayntz |first=Melissa |date=2019-04-26 |title=On the 1st Of The Month Say "Rabbit Rabbit" for Good luck! |url=https://www.farmersalmanac.com/rabbit-rabbit-35150 |access-date=2023-04-27 |website=Farmers' Almanac – Plan Your Day.

The "rabbit test" is a term first used in 1949 for the [[Rabbit test|Friedman test]], an early diagnostic tool for detecting a pregnancy in humans. It is a common misconception (or perhaps an [[urban legend]]) that the test-rabbit would die if the woman was pregnant. This led to the phrase "the rabbit died" becoming a euphemism for a positive pregnancy test.<ref>{{Cite journal |last=Friedman |first=Maurice |title=The Assay of Gonadotropic Extracts in the Post-Partum Rabbit11 |date=1 May 1939 |url=https://doi.org/10.1210/endo-24-5-617 |journal=Endocrinology |volume=24 |issue=5 |pages=617–625|doi=10.1210/endo-24-5-617 }}</ref>
