A narluga (portmanteau of narwhal + beluga) is a hybrid born from mating a female narwhal and a male beluga whale.[1] Narwhals and beluga whales are both high Arctic cetaceans and the only two members of the family Monodontidae.[2]

Discovery[edit]

The existence of narlugas had been hypothesized for decades before its discovery. There are only 20 in existence, with only 7 of those in captivity.[3] In 1990, Mads Peter Heide-Jørgensen discovered a skull belonging to an unknown Monodontidae, with descriptive properties between a narwhal and a beluga. In particular, the characteristic narwhal 'horn' is anatomically a tooth; the unidentified specimen lacked a single narwhal tusk, but its teeth were spiralled, like the tusk of a narwhal.[4][3]

The genetic identity of the narluga was confirmed in 2019 when the genome of the specimen was sequenced.[1]
