Description

The toothed ponyfish is a small, silvery schooling fish of the family Leiognathidae reaching about 21 cm. The deep, strongly compressed body gleams silver and has a remarkably protrusible, tube-like mouth with which the fish sucks prey from the water or the bottom. Unlike most ponyfishes, this species has true teeth in the jaws. Like related species it has a light organ with luminescent bacteria around the gullet, giving a soft glow. The species lives in schools in shallow coastal waters, lagoons and river mouths of the Indo-Pacific, over soft bottoms. It hunts small zooplankton and bottom animals. In Asia it is eaten fresh and dried.
