Distribution map of Mimocalanus crassus by geographical zones
Loc:
Mer des Antilles, Caribbean Colombia, G. du Mexique, Indien W, Arct. (all polar Basins, Canada Basin, Makharov basin, Amundsen Basin, Nansen Basin)
N: 6
Lg.:
(13) F: 1,27-0,95; M: 1,36-0,78; (67) M: 0,78; (88) F: 1,22-1; M: 1,3; {F: 0,95-1,27; M: 0,78-1,36}
Rem.: bathypelagic-abyssopelagic.
The species is close in habitus to M. cultrifer Farran (1908).
For Park (1970) the males described by Grice & Hulsemann (1967) from the Indian Ocean seem belong to M. crassus.
