Biologia     Glossario (es. epibenthic)

Found on the continental shelves and upper slopes from inshore to deeper waters. Prefers rocky, algal-covered areas of kelp beds. Nocturnal. Feeds on bony fishes, alive and dead, and probably crustaceans. Can inflate its stomach with water or air. Oviparous. Can live in tanks for several years and females can lay eggs in captivity. Occurs in aggregations while resting, sometimes piled one on top of the other. Sometimes caught by sport divers but not used.
