Wrasses are a large and diverse family of marine fish. With over 600 species in 81 genera, many of them are bright with different colors. Easily found worldwide in tropical and temperate seas, Wrasses are often abundant among coral reefs.
Some small wrasses, however, act as cleaners for larger fishes. They pick off and eat the external parasites of groupers, eels, snappers, and other fishes that visit them periodically.
Some wrasses are male and female throughout life; however, most are protogynous hermaphrodites (that is, they function first as females before transforming into males). In addition, some species may have primary males, as well as sex-reversed females.
