Description

The spotted soapfish (Rypticus subbifrenatus) is a sea bass relative of the family Serranidae from the western Atlantic and Caribbean. The species has a stocky, dark-brown body with numerous small pale and dark spots and reaches about 18 cm. It inhabits clear tropical waters to about 26 metres deep, but is most often found in very shallow water. It is a shy, secretive fish that stays among rocks and coral and hunts fishes and crustaceans at night. Soapfishes secrete a toxic, bitter mucus (grammistin) when disturbed, which foams in water; for this reason the species is not eaten.
