Open encyclopedia reference
Eumecichthys fiski, the unicorn crestfish or unicornfish, is a very rare, little-known species of crestfish in the family Lophotidae, and the only member of the genus Eumecichthys. It likely has a worldwide distribution, having been first discovered offshore of Kalk Bay, South Africa, and subsequently reported from the Sea of Japan, southwest Florida, Clarion Island off Mexico, Hawaii, and India. Reports from the Bering Sea are likely erroneous. It is found in the bathypelagic zone, at depths around 1,000 m (3,300 ft).
