The sunfish family - Centrarchidae includes 30 species, and is found only in North America. They all are characterized by having at least one spine ray at the front part of the dorsal fin, which is continuous with the rear portion. Their body is deeply compressed laterally, and the attachment of the pelvic fins is far forward, nearly beneath the pectoral fins. There are three or more spines at the front of the anal fin, and the scales are ctenoid, which means they have rough edges.
