The Atlantic wolffish (Anarhichas lupus), also known as the Seawolf, Atlantic catfish, wolf eel (the common name for its Pacific relative), or sea cat, is a marine fish, the largest of the wolffish family Anarhichadidae. The numbers of the Atlantic wolffish are rapidly depleting due to overfishing and by-catch, and is currently a Species of Concern according to the National Oceanic and Atmospheric Administration's (NOAA) National Marine Fisheries Service (NMFS)[1]. Although it is a fearsome looking creature, the Atlantic wolffish is only a threat when defending itself outside of the water. Besides for its unique appearance, some of its distinguishing characteristics include: the natural antifreeze it produces to keep its blood moving fluidly in the very cold water where it lives, a mutual effort by both the female and male in brood bearing and the large size of their eggs. They are also an important factor in keeping green crab and sea urchin numbers down, who can become an invasive species when their population size gets too big. Their population success is also an important indicator on the health of other bottom dwellers populations, such as cod
