Description

The goldstripe ponyfish is a small silvery fish of the family Leiognathidae from the Indo-West Pacific. The species reaches about 14 cm and has a deep, compressed body and a highly protrusible, tube-like mouth with which it sucks prey from the bottom. It occurs in shallow coastal waters, mainly over muddy bottoms, and usually lives in schools. The diet consists of polychaetes, bivalves, small crustaceans and sponges. Around the oesophagus it has a light organ with luminous bacteria that makes the belly glow faintly. The species is regularly caught in coastal fisheries and eaten.
