Atlantic Wolffish (Anarhichas lupus)
The Atlantic wolffish is a marine fish, the largest of the wolffish family Anarhichadidae. The numbers of the Atlantic wolffish are rapidly being depleted, most likely due to overfishing and bycatch, and is currently a Species of Concern according to the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service. Although it looks fearsome, the Atlantic wolffish is only a threat to humans when defending itself out of the water. Apart from their unique appearance wolffish are distinguished by the natural antifreeze they produce to keep their blood moving fluidly in their very cold habitat, involvement by both the male and female in brood bearing, and the large size of their eggs. Atlantic wolffish use their strong jaws to eat hardshell mollusks, crustaceans, and echinoderms. They do not eat other fish.
