Description

The tessellated notothen is a cold-water fish of the notothen family (Nototheniidae) from the south-western Atlantic and south-eastern Pacific around southern South America. The species grows to about 28 cm and has a stocky body with a tessellated, mottled pattern that provides good camouflage on rocky bottoms. It inhabits shallow coastal waters and kelp forests in the cold waters around Tierra del Fuego and the Falkland Islands. As a bottom hunter it feeds on small crustaceans, molluscs and worms. The male guards the eggs laid on the bottom. The species is locally important as prey and is harmless to humans.
