Until they hatch, egg masses are constantly protected by one or both parents. This species strong, heavy jaws are perfectly designed for eating crunchy, shelled invertebrates such as sea urchins and crabs, as well as other fish. A bite from the jaws of a wolf eel can cause considerable damage, however the species has a gentle reputation among divers: once coaxed out of its hiding place by the promise of hand-fed food from divers, an individual may readily emerge to greet other divers. Its range extends from Northern Baja California north to the Aleutian Islands, Alaska, and east and south to the Seas of Okhotsk and Japan. The wolf-eel is a slow-moving, reclusive fish that hides away near the sea bottom in crevices and caves, often using an individual location as a semi-permanent den. Juveniles are orange and more conspicuously spotted this colouring fades as they mature. 2 The male and female may pair for life and inhabit a cave together the two watch their eggs together and one always stays behind when the other leaves to feed. Both are mottled with dark spots surrounded by pale rings, and the degree of mottling tends to increase with size. A pair of wolf eel with eggs (pale yellowish) Large wolf eels are curious 13 and are rarely aggressive, but are capable of inflicting painful bites on humans. Well, theyre bastards.Ive been bitten by them and snowflakes numerous times.Mostly theyre pretty shy i guess. Despite not being a true eel, the wolf-eel's common name succinctly sums up its long and narrow body, rather vicious-looking snaggly teeth, and impressive size (it can reach 2.5 m long!) While both male and female have large heads tapering into elongated bodies with long anal and dorsal fins, they are readily differentiated as the female is darker and brownish in colour, while the male is whitish-grey male and has a bumpier, puffier head with a bulging forehead and large jaws.
The wolf-eel is a distinctive fish unrelated to other 'true' eels it instead belongs to the wolffish family ( Anarhichadidae).
