Sealfish

Sealfish is a common name applied to several species of fish that bear a superficial resemblance to seals or are found in their habitats. Primarily, it refers to the anglerfish family, Lophiidae, particularly species like the monkfish (Lophius piscatorius). These fish are characterized by their flattened bodies, wide mouths, and a lure-like appendage that they use to attract prey. Their rough, mottled skin allows them to camouflage effectively on the seabed, making them ambush predators. Sealfish are found in marine environments worldwide, often inhabiting sandy or muddy bottoms at moderate depths.

Another group sometimes referred to as sealfish are certain species of the family Phocidae, which are true seals. However, this usage is less common and can lead to confusion with the anglerfish. When the term sealfish is used in a culinary context, it almost exclusively denotes the monkfish due to its dense, white flesh, which is considered a delicacy in many parts of the world. The monkfish is a bottom-dwelling predator, feeding on other fish and invertebrates. Its unique appearance and hunting strategy have led to its distinctive common name.
