Denmark. Abstract.
- Until about 15 years ago, the holotype of Harriotta haeckeli
Karrer, 1972 was the only chimaeroid fish recorded from Greenland waters.
Between 1988 and 2002, several specimens of four additional chimaeroid
species were caught in deep-sea trawl surveys (400-1500 m) for Greenland
halibut: 65 specimens of Hydrolagus affinis (Capello, 1868), 1
specimen of H. pallidus Hardy & Stehmann, 1990, 1 specimen
of Chimaera monstrosa Linnaeus, 1758 and 2 specimens of Rhinochimaera
atlantica Holt & Byrne, 1909. The new records extend the distribution
ranges considerably to the north and/or west. All specimens are adults
except for a juvenile C. monstrosa (80 mm body length-BL) and a
juvenile H. affinis (140 mm BL). Juveniles of chimaeroid fishes
are very rarely caught, so they are here described with comments on dermal
denticles, allometric growth and colouration. |
