Awholphin (portmanteauofwhale and dolphin) is an extremely rare cetacean hybrid born from a mating of a female common bottlenose dolphin (Tursiops truncatus) with a male false killer whale (Pseudorca crassidens).[1] The name implies a hybrid of whale and dolphin, though taxonomically, both are in the oceanic dolphin family, which is in the toothed whale clade. This type of hybrid was considered unexpected given the sometimes extreme size difference between a female common bottlenose dolphin (typically 2 meters long and 300 kilograms) and a male false killer whale (over 5 meters long and over 1,800 kg). Wholphins have been born in captivity and have also been reported in the wild.[2]
The first recorded wholphin was born in a Tokyo SeaWorld in 1981; he died after 200 days.[3]
The first wholphin in the United States and the first to survive was Kekaimalu, born at Sea Life ParkinHawaii on May 15, 1985; her name means "from the peaceful ocean".[3] Kekaimalu proved fertile when she gave birth at a very young age. The calf died after a few days. In 1991, Kekaimalu gave birth again, to her daughter, Pohaikealoha. For two years, she cared for the calf, but did not nurse it; it was hand-reared by trainers. Pohaikealoha died at age 9. On December 23, 2004, Kekaimalu had her third calf, daughter Kawili Kai, sired by a male bottlenose. The calf did nurse and was very playful. Only months after birth, it was the size of a one-year-old bottlenose dolphin.[4] All three calves were three-quarters bottlenose dolphin and one-quarter false killer whale.[5] , Kekaimalu died on July 8, 2024 at the age of 39. [6] Kawili Kai remains in captivity in Sea Life Park.[7]

Born at Sea Life Park on May 15, 1985, Keikaimalu was referred to as a wholphin by Sea Life Park's training staff.
The first captive wholphin, Kekaimalu, was born on May 15, 1985, to a female bottlenose dolphin named Punahele, who shared a pool with a male false killer whale named Tanui Hahai. The wholphin's size, color and shape are intermediate between the parent species. She has 66 teeth – intermediate between a bottlenose (88 teeth) and false killer whale (44 teeth)
