A general term for marine fishes belonging to the Cetominimidae, Barbourisiidae, and Rondeletiidae families of the Cetacean order. Body length is usually 10-20 cm. The head and mouth are generally remarkably large, with the head length reaching 1/4-1/3 of the body length. The eyes are degenerate, and the eye diameter is usually less than 1/7-1/10 of the length of the upper jaw. The large mouth and tiny eyes are reminiscent of a whale, hence the name. They are found in the deep seas of the open ocean all over the world, living in layers far from the bottom. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
