Atlantic wolffish resting next to a plumose sea anemone. The Atlantic wolffish (Anarhichas lupus) inhabits the rocky bottoms of the north-eastern and north-western Atlantic Ocean coasts, where it feeds on hard-shelled molluscs, sea urchins, crabs and lobsters. Plumose sea anemones (Metridium senile) are found mostly in the cooler waters of the northern Pacific and Atlantic oceans.
