The roughskin spurdog is a widespread species of dogfish found in warm and temperate waters of the Atlantic, Pacific, and Indian Oceans, at depths of 200 to 650 m. It is most common along the Atlantic coast of the United States.
These sharks are ovoviviparous and have large litters of sometimes over 20 pups. They grow to a maximum length of 1.2 m. Adults feed on bony fishes and squid.
They’re often caught caught by trawl and longline fisheries, but it’s unclear how this affects their population. The facts that they have several pups and are widespread gives them an advantage, but population studies need to be done. At the moment they’re considered data deficient.
