ECHINODERMATA, ASTEROIDEAIN THE FAROE AREA
BioFar 2 stations: 1190(1)
Other records: The H. perforata-group probably con-
tains the three species: H. perforata, H. eschrichti
and H. oculata (Ringvold 1996). The species H.
perforata is, according to Madsen (1987), common
in the Faroes.
Bathymetrical range within the area: 80 - 923 m
(mainly: 80 -650 m)
Substrate: clay, sand, shell-sand, gravel, stones
Temperature: 0.3° - 4.2 °C (measured); estimated: 0 -
9.1°C
Water mass: AW, AW/AI, AI, AI(NW
World distribution: H. perforata has a wide Atlantic
boreo-arctic distribution. It is the most common
Henricia species in Scandinavia and is found east
to Øresund. The species is also common in the
Faroes, Iceland, Greenland, Svalbard and along the
northem Russian coast east to the East Siberian
Sea. On the East American coast the species is
found from Labrador to Hudson Bay.
World bathymetrical range: 2 - 1,200 m (Madsen
1987)
Remarks: The genus Henricia is rather polymorphic
and thus it is difficult to determine the species (see
Madsen 1987, Ringvold 1996 for electrophoretic
studies).

Other records: H. pertusa-group contains the species
H. pertusa, H. sanguinolenta, H. hedingi, H.
spongiosa, H. cylindrella and H. lisa ingolfi
(Madsen 1987, Ringvold 1996); H. sanguinolenta
is found in the Faroe-Shetland Channel (Bell 1892)
and it is common around the Faroes (Lieberkind
1929, Madsen 1987).
Bathymetrical range within the area: 21 - 1,150 m
Substrate: clay, sand, shell-sand, gravel, stones
Temperature: -0.6° - +3.5°C (measured); estimated: -
0.9° - +8.7°C
Water mass: AW, AW/AI, AI, AI/NW, NW
World distribution: According to Madsen (1987), H.
sanguinolenta is common along the Norwegian
coast from Skagerrak to North Cape, the northern
part of the Norwegian Sea and the Barents Sea
north to Svalbard, Iceland and the Faroes.
D’yakonov (1950) reports the species also from the
Southwestem Barents Sea east to the Kolafjord,
Motovskii Bay and north of Kildin Island. In the
W. Atlantic the species is found from
Massachusetts to Fundy Bay (Madsen 1987).
World bathymetrical range: 30 - 1,400 m (Madsen
1987 for H. sanguinolenta)
Remarks: The H. pertusa-group was the most
common of all the asteroid species found during
BioFar as it was found on 166 of a total of 316
stations containing asteroids (53%).
