Fin's Fish Guide
The Mottled soapfish (Rypticus bicolor) is a saltwater fish of the family Serranidae that grows up to 28 cm.
Description
The soapfish is a soapfish (Serranidae) from the eastern Pacific. The species has a stocky, brownish body with a smooth, slimy skin. It lives on rocky reefs, where it shelters in caves and crevices but is also seen in the open, often lying motionless in wait. As an ambush hunter it feeds on small fishes and crustaceans. When disturbed its skin secretes a toxic, soapy mucus (grammistin) that deters predators; avoid contact with this mucus and do not eat the fish.
