Description

The hogchoker is a small, right-eyed sole of the family Achiridae (American soles) reaching about 20 cm. The round, brown body has a rough skin, dark cross-bars and lacks pectoral fins; both eyes lie on the right side. The species is extraordinarily salt-tolerant and lives in estuaries, lagoons and the lower reaches of rivers along the western Atlantic coast from the USA to South America; it runs far into fresh water. On the muddy bottom it searches, mainly at night, for worms, small crustaceans, insect larvae and detritus. The name 'hogchoker' refers to its rough skin, on which pigs were said to choke. Because of its small size it has little fishery value.
