Úrtak
Tvey sløg av caprellidea, sum ikki fyrr høvdu verið
skrásett í sjónum kring Føroyar, vórðu eyðmerkt undir
BIOFAR-verkætlanini, og tað loddrætta útbreiðsluøki
hjá nøkrum øðrum sløgum, sum longu vóru kend í um-
ráðnum, vaks. Caprellidfaunan kring Føroyar er ein løg-
in blanding av sløgum, ið liva í heitum sjógvi, og sløg-
um, ið liva í køldum sjógvi, sum koma fyri í óvanligum
temperaturum. I greinini er ein listi yvir caprellidsløg í
Føroyum saman við viðmerkingum um landafrøðiligu
og loddrøttu útbreiðslu teirra, og eisini eru lyklar til
caprellidea í Norðuratlantshavi.
Abstract
During the BIOFAR program, two species of caprellids
previously unrecorded from the waters surrounding the
i iroe Islands where identifíed, and the vertical distribu-
tion range increased for a number of other species al-
ready known from the area. The caprellid fauna around
the Faroes islands is a peculiar mixture of warm and
cold water species, found at unusual temperatures. A
species list of the caprellids from the Faroe Islands to-
gether with notes on their geographical and vertical dis-
tribution, and keys to the North Atlantic Caprelliđea are
given.
Introduction
The caprellid fauna around the Faroe Is-
lands was previously recorded by Stephen-
sen (1929). This, otherwise comprehensive
work, was limited by the fact that few deep
water surveys had been made at that time
despite the fact that, bathymetrically and
hydrographically, this is a very interesting
area. One of the few deep water surveys
which had been done was the Danish Ingolf
Expedition, but the caprellids from this ex-
pedition had not been processed at that time
(Stephensen, 1944).
The hydrography of the region is known
to be very complex (Westerberg, 1990.
Hansen, 1984. Stein, 1988. Malmberg and
Kristmannsson 1992). A number of caprel-
lid species (Aeginella spinosa, Caprella mi-
crotuberculata, Metacaprella horrida, Ph-
tisica mariner) have been found way out-
side their known temperature range. This is
considered to be a reflection of the complex
hydrography. Fossá et al. (1992) reported a
close correlation between species composi-
