Description

Randall's soapfish is a soapfish from the western Atlantic, ranging from the West Indies and Panama to Santa Catarina in Brazil. The species grows to about 20 cm and has a stocky, brownish body. Soapfishes take their name from a soapy, bitter and mildly toxic skin mucus (grammistin) that they secrete when disturbed as a defence. As a bottom-dweller the fish lives on reefs and hunts small prey. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
