Myripristinae

Myripristinae is a subfamily of ray-finned fish belonging to the squirrelfish family Holocentridae. This subfamily is characterized by its generally large eyes, which are adapted for nocturnal activity, and its bright red or reddish coloration, which helps with camouflage in dimly lit reef environments. Myripristinae species are found in tropical and subtropical waters of the Atlantic, Indian, and Pacific Oceans, typically inhabiting coral reefs, rocky shores, and seagrass beds. They are predominantly nocturnal predators, feeding on small invertebrates such as crustaceans, mollusks, and echinoderms, as well as small fish. During the day, they seek shelter in crevices and under ledges.

The subfamily Myripristinae includes several genera, with Myripristis being the most prominent. Common characteristics include a compressed body, a continuous dorsal fin with distinct spiny and soft-rayed sections, and a relatively large mouth. The spines in the dorsal fin are sharp and can be used for defense. Spawning typically occurs at night, and the eggs are usually pelagic, drifting with the currents before hatching. While some species are solitary, others may form small aggregations. Myripristinae are not typically targeted by commercial fisheries, but they are sometimes caught as bycatch or for the aquarium trade. They are generally considered non-aggressive towards humans.
