Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine anali: 0; Raggi anali molli: 200. Dorsal with 228-250 spines. Caudal small. Anal with up to 233 rays.
Body shape (shape guide): elongated.
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). Its flesh is tasty (Ref. 28499).
Ciclo vitale e comportamento di accoppiamento
Maturità | Riproduzione | Deposizione | Uova | Fecondità | Larve
When courting, the male wolf-eel butts his head against the female's abdomen, wraps around her, and fertilizes her eggs as she extrudes them. Eggs are laid and both male and female wrap themselves around the egg mass to protect it . Only one parent at a time leaves the eggs to feed. The female periodically rotates the eggs until they hatch. A male and female may pair for life (Ref. 28499).
