Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951). |

Brodsky & al. (1983, p.260) consider that there is no synonymy between the males of this species and those of S. spinipes.
For Rose (1937, p.157) Spinocalanus heterocaudatus differs from S. magnus, also observed in Alger's Bay.
For Vervoort (1957, p.42) this species is closely allied with Spinocalanus antarcticus. According to Wolfenden's description the female of S. anracticus have the A1 slightly shorter (they reach the 3rd urosomal somite), the lateral thoracic margin is less produced, whilst there are additional small differences in the proportional lengths and shape of the cephalothorax and urosome. Comparison of the drawings of females of both forms in dorsal aspect in Wolfenden (1911, textfigs. 8, 9) gives the impression that two widely different species have been figured. In spite of these discrepancies in general outline of the body, Vervoort is not fully convinced that the two forms are really so very different.
Sano & al. (2013, p.21) indicate that this species (in the present study) selectively fed on sinking aggregates that contained fresh phytodetritus. The gut contents consisted of small particles of diverse origin, indicating dentrivory/omnivory, however, the analysis further demontrated the predominance of diatoms fragments and lesser crustacean fragments, indicating that the species in Sagami Bay fed mainly on foods of phytoplankton origin.

For Bode & al. (2017, p.610), S. magnus and S. antarcticus could only be separated based on their body shape [Criterion debatable. CR.] | | | Last update : 28/03/2020 | |
