Aequidens
Genus of fishes
From Wikipedia, the free encyclopedia
Aequidens is a genus of fish in the family Cichlidae found in South America. Formerly a wastebasket genus, as presently defined Aequidens is largely restricted to the Amazon Basin, Orinoco Basin and river basins in The Guianas. The only exceptions are A. plagiozonatus which also occurs in the Paraná Basin, and A. tetramerus which also occurs in the Parnaíba River.[1]
