Marshall Islands Anthias (Anthiadidae)

We are using Anthias as a general term for species in the Anthiadidae.. Here at Kwajalein, most Anthias species live out on the seaward reef slope, with some species found only within the deeper ranges of sport diving depths. There are likely other unrecorded species even deeper. Often they form small or large groups sometimes consisting of more than one species, and feed on passing plankton. Many species will dive into holes in the reef when threatened, and in those holes they sleep at night. Most species are sexually dimorphic, with generally a few colorful males mixed in with larger groups of less colorful females. Females can become males if needed.
