About Serranocirrhitus latus Watanabe, 1949
This species, commonly called the hawkfish anthias, has a notably deeper body than other members of the subfamily Anthiinae. It has elongated pectoral fins that extend to the rear portion of the anal fin. The fish's overall body color is pinkish, and each individual scale bears a bright yellow to orange marking. Two bright yellow stripes radiate out from the back of the eye, and there is an additional yellow spot on the operculum. Its dorsal fin has 10 spines and 18–20 soft rays, while the anal fin has 3 spines and 7 soft rays. The maximum recorded total length for this species is 13 centimetres (5.1 inches). The hawkfish anthias ranges from southern Japan, specifically the Ryukyu and Izu Islands, and Taiwan, southward to the Great Barrier Reef and Palau. It occurs as far west as the Moluccas and as far east as Tonga. This species inhabits inshore waters near coral reefs, at depths between 10 and 70 metres (33 to 230 feet). It may be found alone or in small groups that typically gather close to caves, overhangs, and drop-offs. It is a secretive species that frequently swims upside down beneath overhangs or cave ceilings, and individuals remain faithful to a specific shelter. Its diet consists primarily of zooplankton. Hawkfish anthias are protogynous hermaphrodites: when a male in a loose aggregation dies or disappears, the dominant female changes sex to become the new male.
