Wrasses are a large and diverse family of reef fish that vary considerably in size. Most are small and elongated, and they have a continuous dorsal fin. The majority of wrasses are beautifully colored. Some exhibit dramatic color-pattern changes with growth and between the sexes, which makes identification difficult. Sex change is common in this family. Wrasses have a distinct swimming style that depends more on the pectoral fins than the tail. All wrasses are carnivorous, but their food habits vary. Among the largest of the wrasses are those belonging to the genus Bodianus, which are commonly called hogfish.
