Description

The whitespotted soapfish is a perch-like fish of the family Serranidae from the western Atlantic. The species grows to about 20 cm and has a stocky, brownish body with pale spots and an upturned mouth. Soapfishes owe their name to the soapy, bitter mucus (grammistin) the skin secretes, which foams when disturbed; it deters predators and makes the fish inedible. It lives on rocky and coral reefs, where by day it lies hidden in crevices. As a nocturnal ambush predator it feeds on small fishes and crustaceans. The species is harmless to humans but is not eaten because of the skin mucus.
