Range of rough longnose dogfish (in blue)

The rough longnose shark (Deania hystricosa) is a little-known deepwater dogfish. This species was described by Samuel Garman in 1906 and originally named Acanthidium hystricosa.[1]

The rough longnose dogfish has an extremely long snout, no anal fin, small grooved dorsal spines, and rough, pitchfork-shaped dermal denticles. The first dorsal fin is long and narrow.

Maximum length is 109 cm.[2] Found in the Eastern Atlantic around Madeira and in the western Pacific around southern Japan , this shark is rarely seen, but lives between 600 and 1,000 m. It is ovoviviparous with probably around 12 pups per litter.[2]

In June 2018 the New Zealand Department of Conservation classified the rough longnose shark as "Data Deficient" under the New Zealand Threat Classification System.[3]
