DECAPODA NATANTIA (CRUSTACEA) IN THE FAROE AREA
Atlantic distribution: From c. 70 °N off Norway to c.
47 °N off Bretagne and Bay of Biscay (Casanova,
1976), and 17-23 °S, Namibia (Macpherson, 1991); the
Faroes; south of Jan Mayen; SW, W and N of Iceland;
from c. 66 °N off West Greenland and 59 °N SE off
Cape Farewell, Greenland to off South Carolina
(Sivertsen and Holthuis, 1956).
Atlantic depth range: 250-2400 m (Sivertsen and
Holthuis, 1956), benthopelagic (Dr. John Mauchline,
Oban, pers. commn).
Family HIPPOLYTIDAE
Genus Bythocaris G. O. Sars, 1870
Note: “A revision of the present genus based on a large
material from numerous different localities is urgently
needed. Without such a material the task of
ascertaining the size and status of the various species
seems to be hopeless.” (Sivertsen and Holthuis, 1956).
