Wolf-eel

Wolf-eel (Anarrhichthys ocellatus)

Hardly a wolf, not really an eel, this fierce-looking fish spends the day quietly in a cave, wriggling out at night to feed. Its body is ideally shaped for living in crevices. They're not dangerous unless provoked.

Though some divers say the wolf-eel can bite a broomstick in half, this predator deserves a better reputation. Wolf-eels chomp on crabs, mussels and urchins; they don't eat divers or their brooms.

A mated pair of wolf-eels share a rocky cave. The female lays her eggs among the rocks and both fish guard them until the young hatch.
