Deania is a genus of long-snouted, deepwater dogfish sharks in the family Centrophoridae.

Species

  • Deania calcea R. T. Lowe, 1839 (birdbeak dogfish)
  • Deania hystricosa Garman, 1906 (rough longnose dogfish)
  • Deania profundorum H. M. Smith & Radcliffe, 1912 (arrowhead dogfish)
  • Deania quadrispinosa McCulloch, 1915 (longsnout dogfish)

Habitats

In the North Atlantic Waters, three species of the genus Deania have been reported; Deania calcea, Deania hystricosa and Deania profundorum. However, in the North Spanish waters, only Deania calcea and Deania profundorum have been caught. [2]

Taxonomy

Deania species have two dorsal fins with strong grooved spines, no anal fin, and a strong sub terminal notch on the caudal fin. Typically, identification characteristics such as dermal denticles and teeth have been utilized to distinguish between elasmobranch species.[2]
