Sexual colour patterns in the sandperch Pseudopercis numida Ribeiro (Osteichthyes, Pinguipedidae)Abstract
This communication deals with the sexual colour patterns in the sandperch Pseudopercis numida Ribeiro, 1903, a benthonic fish of commercial importance, endemic to the Brazilian continental shelf, occurring off the coasts from Espírito Santo to Rio Grande do Sul States. The males have the head, the dorsal part of the body, and the pectoral and caudal fins blackishes, whereas the females have them brown-yellowishes. Such patterns are constant characters, not related to maturity or breeding seasons.
