Description

The dwarf dory is a small dory of the family Zeniontidae (dwarf dories) reaching about 16 cm. The deep, strongly compressed, silvery body has large eyes and a far-protrusible, tube-shaped mouth - an adaptation to suck in small prey in a flash. The species is a deep-water dweller widely distributed above the continental slope of warm and temperate seas worldwide. There it feeds on small zooplankton and small crustaceans. Because of its small size and deep lifestyle it has no fishery value and is only rarely seen.
