A general term for marine fishes belonging to the family Lophiidae (Anglerfishes). Widely distributed from temperate to tropical regions, they inhabit the somewhat deep seabed in coastal areas. The body is black-brown, and the head is disk-shaped and significantly flattened vertically, as if it had been crushed from above. The skin is smooth and scale-free, with many cortical projections. There are three to four spines in the front of the dorsal fin that are free from each other. The first spine is the longest and is located near the tip of the snout, and its tip is modified into a skin flap that is swung to attract and prey on small fish.
