The large and ferocious-looking Wolf-fish (Anarhichas lupus) is normally found on rocky reefs in deep water. However, north of the British Isles, divers regularly see them in shallow water. They are not aggressive to divers unless provoked. The wolf-fish has a long body and a huge head with strong caninelike teeth at the front and molarlike teeth at the sides. These are used to break open hard-shelled invertebrates such as mussels, crabs, and sea urchins. Worn teeth are replaced each year. The skin is tough, leathery, and wrinkled and is usually grayish with darker vertical bands extending down the sides.
Spawning takes place during the winter. The female lays thousands of yellowish eggs in round clumps among rocks and seaweeds and the male guards them until they hatch. In spite of their unattractive appearance, wolf-fish are good to eat and are caught by anglers. They are also sometimes caught in trawl nets.
I dedicate this post to my friends down at Stony Brook. ;)
