Pinguipes brasilianus, commonly known as the Brazilian sandperch,[2] is a species of ray-finned fish in the family Pinguipedidae.

[1] Charles Darwin records the crew catching this fish with hook and line off the coast of northern Patagonia, at a time when the Beagle was anchored during bad weather.

Its range extends from Rio de Janeiro in Brazil southwards to Golfo Nuevo in Argentina.

[6] Breeding takes place over an extended period of spring and summer, peaking between October and February.

Females reach 50% maturity at an average total length of about 15 cm (6 in) and have a fecundity ranging from 2 to 44 oocytes per gram for medium size fish.
