Rough sharks are small to medium in size, ranging from 49 to 150 cm (1.61 to 4.92 ft) 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.
