Goatfishes are characterized by a
streamlined body with two dorsal fins, a forked tail, slightly inferior
mouth suited for bottom-feeding, and a pair of chin whiskers called
barbels. These barbels
are used to actively probe, excavate, and detect hidden invertebrates and small
fish. They tend to occur in small groups or aggregations for
safety and move quickly when disturbed. Most species are capable
of changing color rapidly and often assume a mottled or barred pattern
at night. Goatfishes are commercially important because their
flesh tastes like shrimp and red fish are a symbol of good luck to Asian
cultures.
