Description

Odontognathus mucronatus, the Guiana longfin herring, is a strongly laterally compressed herring-like fish of the family Pristigasteridae from coastal waters of northern South America. The species has a translucent, silvery, knife-shaped body with a very long anal fin and reaches about 22 cm. It occurs close inshore, off river mouths, in estuaries and sometimes travels some distance into fresh water, far up the Coppename in Suriname. It lives over sand and mud bottoms and feeds on plankton. The species forms schools and is of limited local fishery importance; it is marketed mainly fresh.
