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.
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.
