What to know about wrasses
A clean field guide focused on habitat, identification, behavior, and conservation context without burying the useful parts.
Wrasses (family Labridae) are a large, diverse group of marine ray-finned fish, with over 600 species in 81 genera divided into eight subfamilies. Many species are brightly colored. Most wrasses are typically small (most less than 20 cm / 7.9 in), though the largest, the humphead wrasse, can reach about 2.5 m (8.2 ft). Wrasses are efficient carnivores feeding on a wide range of small invertebrates. Some smaller wrasses follow feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of several genera (including Bodianus, Epibulus, Cirrhilabrus, Oxycheilinus, and Paracheilinus) may hide among the tentacles of free-living mushroom corals such as Heliofungia actiniformis.
