Crocodile attacks on humans are common in places where large crocodilians are native and human populations live. It has been estimated that about 1,000 people are killed by crocodilians each year.[1]
The two species with the most well-known and documented reputation for preying on humans are the Nile crocodile and saltwater crocodile, and these are the perpetrators of the vast majority of both fatal and non-fatal crocodilian attacks.[1] Each year, hundreds of deadly attacks are attributed to the Nile crocodile in Sub-Saharan Africa. Attacks by saltwater crocodiles often occur in Southeast Asia, Australia, New Guinea, and the Solomon Islands. Reviews indicate that at least half of all attacks by the Nile and saltwater crocodiles are fatal[1] (in Australia, however, only about 25% of saltwater crocodile attacks are fatal).[2] The mugger crocodile is also very dangerous to humans, killing several people in India every year and with a fatality rate that is almost as high (slightly less than half of all attacks are fatal).[1] Unlike the predatory attacks by Nile and saltwater crocodiles, victims of mugger crocodiles are often not eaten, indicating that many attacks by this species are territorial or defensive rather than predatory.[3] Crocodilians will defend not only themselves, but also their nest and young from anything they perceive as a threat.[2]
Eight other species have been involved in fatal attacks on humans, but in far lower numbers than the Nile, saltwater and mugger crocodiles, and also with significantly lower fatality rates (a higher percentage of their attacks are non-fatal).[1] These are the American alligator (making up an estimated 6% of fatal crocodilian attacks),[2] West African crocodile (often considered quite harmless,[4] but has been involved in several attacks, also fatal),[5] American crocodile (only a few documented fatalities),[3][6][7] the Morelet's crocodile (typically considered a relatively non-threatening species, but there have been several fatal attacks),[7][8] Orinoco crocodile (fatalities recorded in the 1930s and earlier when the species was more common, but today it is very rare),[9][10] Cuban crocodile (generally considered aggressive, but only one confirmed fatality),[3][11] black caiman (fatal attacks confirmed in Brazil, but possibly underreported because of its remote range),[3] false gharial (only a few confirmed fatalities, all involving very large false gharials)[3][12] and gharial (a single known fatality, without consumption).[13]
In addition to these, the freshwater crocodile, Philippine crocodile, Siamese crocodile, broad-snouted caiman, spectacled caiman and yacare caiman have been involved in non-fatal attacks.[1][3][14] Four of them, the Siamese crocodile, broad-snouted caiman, spectacled caiman and yacare caiman, each are suspected to have been the perpetrator of a single fatal attack on a child (smaller and therefore a more likely target than an adult), although for each of these cases the identity of the species is not completely certain.[15][16][17][18]
An accurate count of annual crocodile attacks on humans is difficult to obtain. Many of the areas in which humans and large crocodiles come into contact are remote, impoverished, or in areas of political unrest. Crocodile attacks are not always reported to local authorities, and some reports are difficult to verify. Nevertheless, some information does exist: for example, it was reported by CAMPFIREinZimbabwe that in the first ten months of the year in 2005 crocodiles were the number one cause of death in humans where wildlife was involved – with the number of deaths cited as 13.
Unlike other "man-eating" crocodiles, such as the saltwater crocodile, the Nile crocodile lives in proximity to human populations, so contact is more frequent. Although most attacks are not reported, the Nile crocodile is estimated to kill hundreds (possibly thousands) of people each year, which is more than all other crocodilian species combined.[19][20] One study posited the number of attacks by Nile crocodiles per year as 275 to 745, of which 63% are fatal, as opposed to an estimated 30 attacks per year by saltwater crocodiles, of which 50% are fatal. In both species, the mean size of crocodiles involved in nonfatal attacks was about 3 m (10 ft) as opposed to a reported range of 2.5–5 m (8–16 ft) or larger for crocodiles responsible for fatal attacks. Since a majority of fatal attacks are believed to be predatory in nature, the Nile crocodile can be considered the most prolific predator of humans among wild animals.[2]
The most deaths in a single crocodile attack incident may have occurred during the Battle of Ramree Island, on February 19, 1945, in what is now Myanmar. Nine hundred soldiers of an Imperial Japanese Army unit, in an attempt to retreat from the Royal Navy and rejoin a larger battalion of the Japanese infantry, crossed through sixteen kilometres (ten miles) of mangrove swamps that contained saltwater crocodiles. Twenty Japanese soldiers were captured alive by the British, and almost five hundred are known to have escaped Ramree. Many of the remainder may have been eaten by the crocodiles, although since this incident took place during an active military conflict, it is impossible to know how many deaths can be directly attributed to the crocodiles instead of combat-related causes.[21]
It is estimated that each year hundreds of people die from crocodile attacks in Africa – many of these attacks are never reported in the media. Without an accurate reporting system in place, crocodile attacks in Africa are difficult to track and very few are reproduced here. The majority of attacks recorded below have occurred in Southeast Asia and Australia.
