Range of the roughskin spurdog (in blue)

The roughskin spurdog (Cirrhigaleus asper) is a dogfish of the family Squalidae, found circumglobally between latitudes 35°N and 35°S, at depths of between 200 metres (660 ft) and 600 metres (2,000 ft). It reaches a length of 1.2 metres (3.9 ft).

The roughskin spurdog is ovoviviparous with 21 to 22 young in a litter.

Taxonomy

[edit]

The roughskin spurdog was first described in 1973 as Squalus asper by British ichthyologist Nigel Merrett. It was later quickly changed to Cirrhigaleus asper.[2] The roughskin spurdog is also known as the roughskin dogfish and roughskin dogshark in English.[3] Genetic and morphological analyses have confirmed that Cirrhigaleus asper is a distinct species within the genus Cirrhigaleus, separate from C. barbifer and C. australis.[4]
