Pronounced CHA kah
Etymology Chaca: The name comes from the local name of the fish, which is probably derived from the sound it makes when irritated.
Identification The species of the catfish genus Chaca are easily identified by their extremely large and severely dorsoventrally depressed head, caudal fin with greatly enlarged procurrent rays, and tuberculate skin, often with fimbriate skin flaps on the head and sometimes on the body. The genus forms the monotypic family Chacidae, whose phylogenetic affinities to other catfishes remains unclear despite numerous studies.
