Description

The longspine squirrelfish (Holocentrus rufus) is a squirrelfish of the family Holocentridae from the western Atlantic and Caribbean. The species has a reddish body with white markings, large eyes and long, sharp fin spines, and reaches about 35 cm. It is nocturnal and inhabits clear coral reefs, where it hides near caves and holes by day; at night it moves to sand and seagrass beds to hunt crabs, shrimps, snails and brittle stars. The large eyes aid nocturnal hunting. On the gill cover and in the fins it bears sharp spines that can cause puncture wounds; in larger specimens there are reports of ciguatera poisoning.
