Vertical distribution abundance of copepodite stages C3 to C6 of Paraeuchaeta spp.
For P. barbata copepodite stages C1 to C6 are included. +: No occurrence; solid line depicts bottom profile (right axis); station 853 over the Yermak Plateau (81°22'N, 6°52'E) is separated from the other stations on the transect; other stations between East Greenland Current, the Fram Strait and the West Spitsbergen Current, into south return Atlantic Current (77°46'N-79°36'N, 6°20'E-7°29'W).
Deep-sea copepods collected from August 20 to September 16, 2006. |

(Baffin Sea, Canadian abyssal plain, Canada Basin, Fletcher's Ice Is., Chukchi Sea, Beaufort Sea, Amundsen Gulf, Nansen Basin, Amundsen Basin, Makarov Basin, Lomonosov Ridge, Laptev Sea, Kara Sea, Barents Sea, Franz Josef Land), Norwegian Sea, Norway, North Sea, Ungava Bay, Kejser Franz Joseph Fjord, Scoresby Sund Fjord, Ameralik & Godthaab fjords (W Greenland), W Baffin Bay, Greenland Sea, Fram Strait, Kongsfjorden, Iceland, Faroe Is., off SE Newfoundland, S Bay of Biscay (in d'Elbée, 2001), off Moroccan coast (in El Arraj & al., 2017) | | | | N: | 60 | | | | Lg.: | | | (3) F: 11-9,8; M: 7,8; (7) F: 10,4; M: 6,21; (22) F: 11-10; M: 8-7,2; (65) F: ± 10; M: ± 8; (377) F: 9,15; (1001) F: 9,40-10,06; {F: 9,15-11,00; M: 6,21-8,00}
The mean female size is 10.090 mm (n = 9; SD = 0.6338), and the mean male size is 7.442 mm (n = 5; SD = 0.7628). The size ratio (male : female) is about ± 0.73. | | | | Rem.: | épi-bathypélagique.
Contrairement à l'opinion de Giesbrecht & Schmeil (1898, p.40) et de Sars (1900, p.58), l'espèce est maintenue par Sars (1903, p.42).
Cette espèce observée dans le sud-est du Golfe de Gascogne nécessite confirmation, comme sur la côte marocaine.
