Description

Achirus achirus is a small flatfish of the family Achiridae (American soles) from coastal waters and estuaries of South America. Like other American soles both eyes lie on the right side of the oval, strongly flattened body, which is sandy-brown and mottled for camouflage. The species reaches about 37 cm and inhabits sand and mud bottoms of estuaries, rivers and coastal creeks to about 20 metres deep; it tolerates strongly varying salinities. It buries itself completely in the sediment, leaving only the eyes exposed to detect prey and predators. The diet consists of small crustaceans and other bottom invertebrates.
