The lumpfish (Cyclopterus lumpus) is a rotund, lumpy, cold-water bottom fish of the North Atlantic, best known not for its flesh but for its eggs: the small, crunchy roe of the female, dyed jet-black or bright red and sold as an inexpensive "lumpfish caviar," the most common budget substitute for true sturgeon caviar. The fish itself is also eaten — fresh, smoked or salted — and the females are sometimes called "henfish" for the great mass of eggs they carry.
