is large and has big lips. The front teeth are like dog or wolf teeth. The back teeth are molars like those of people.

Geographic range: Wolf-eels live along the coast of North America from Alaska to California.

Habitat: Wolf-eels live on deep rocky reefs in caves or crevices. The young live in open water.

Diet: Wolf-eels eat crabs, clams, mussels, sea urchins, sand dollars, and snails. The young eat plankton.

Behavior and reproduction: Wolf-eels hide and live alone or with a lifelong mate in a den. They hunt at dusk and dawn but also feed during the day. Wolf-eels grab their prey, or animal hunted and killed for food, with their large front teeth and crush it with their molars.

Wolf-eels form pairs when they are about four years old and first lay eggs when they are about seven years old. In courtship the male repeatedly bumps the female's belly. When the female is ready, the male coils around her. The eggs are fertilized as they are laid in clumps, and the female gathers the clumps up into a ball and wraps around them, turning them once in a while so that they all get enough oxygen. Both parents guard the nest, and one always stays with the nest while the other looks for food. Young wolf-eels swim freely for up to two years then settle on the bottom until they begin their den life.

Wolf-eels and people: Wolf-eel tastes good and is caught by scuba divers and fishermen. Wolf-eels have been known to snap at fishermen and can inflict serious bites on scuba divers who spear them.

Conservation status: Wolf-eels are not threatened or endangered.
