Sampling depth (Antarct): 1200 m. 2000-3000 m (in Bode & al., 2017 at 25°S) Typical bipolar species, but taken in the north Arabian Sea in the upwelling from the depth water current originates from Antarctic. For Vervoort (1957, p.42) the male specimen attibued by Wolfenden (1906, p.43, Pl.14, figs. 6, 7; 1911, p.218) to S. antarcticus, certainly does not represent a male of the genus Spinocalanus (probably it belongs to the genus Xanthocalanus). According to Wishner & al. (2008, p.163) this copepod, common in the lower oxycline, fed primarily on compenents of the vertical particulate flux and suspended material. For Bode & al. (2017, p.610), S. antarcticus and S. magnus could only be separated based on their body shape [Criterion debatable. CR.] | | | Last update : 26/11/2020 | |
