The Arrowhead dogfish (Deania profundora) is a decently-sized carnivore, reaching a maximum length of 1.04 metres but usually average around 80 cm. This makes it the smallest of the Deania genus! Found on the upper continental and insular slopes of its range (such as the Canary Islands, the Azores, off Namibia and in the Gulf of Mexico), they are observed at a depth range of 275 metres to 1,785 metres deep.
Little is known about these deepsea sharks. They are dark all over, have a long snout, lack an anal fin, and their dorsal fins are armed with dorsal spines. They are viviparous with yolk sac and produce 5-7 pups.
It is often found in huge schools... which is a problem since they can quickly be wiped out by commercial fisheries in these areas. Deepwater fisheries operate over much of its range and are taken on longlines off the Canary Islands and utilized for their liver oil and meat. The IUCN has assessed them as Least Concern (LC).
