Adults seek shelter among rocks in subtidal areas (Ref. 2850) and will occupy the same shelter until driven out by larger wolf-eels or a large octopus (Ref. 28499). Juveniles are pelagic for up to two years (Ref. 28499). Feed on hard-shelled invertebrates and fishes (Ref. 2850). Both male and female wrap their body around the egg mass to keep the eggs in place and to deter predators (Ref. 58332). Large specimens can inflict a painful bite (Ref. 28499).
