Distribution map of Scaphocalanus polaris by geographical zones
Loc:
Arct. (Nansen Basin, Canadian abyssal plain, Lomonosov Ridge, Amundsen Basin, Laptev Sea, Fletcher's Ice Is., Makarov Basin, Canada Basin)
N: 9
Lg.:
(22) F: 4; {F: 4,00}
Rem.: Bathypelagic-abyssopelagic.
Genus poorly secured but probable.
For Brodsky (1967, p.253) this species differs from the closely related Scaphocalanus medius in the greater size, longer A1, and P5 3-segmented.
For Vyshkvartzeva (1987, p.1576) the species shows as S. acutocornis the exopodite of Mx1 with 8 setae.
