(Oxynotidae)
Rough Sharks
Грубі акули
Oxynotus is a family of sharks in the order Squaliformes, commonly known as the rough sharks. They live in deep waters in the Atlantic and western Pacific Oceans.
Rough sharks are small to medium in size, ranging from 49 to 150 cm in adult body length, depending on species. Their bodies are compressed, giving them a triangular cross-section. They have two large dorsal fins, each with a sharp spine, and with the first fin placed far forward above the head. Even more so than their relatives, the dogfishes, they have rough and prickly skin. Unusually among sharks, they also possess a luminous organ.
Rough sharks inhabit the continental shelf, typically at depths of 200–1,000 m, although they may occur as shallow as 40–45 m. They feed on bony fishes and deep-sea mollusks. They are viviparous.
