Remarks

bathy-abyssopelagic.
Sampling depth (Antarct.) : 1000-2000 m. 800-1000 m (in Bode & al., 2017 at 11°N-25°S).
Damkaer and Brodsky & al. do not agree on the synonymies (Cf. S. dorsispinosus Male & S. longispinus Female).
According to Vervoort (1946, p.154) this species is synonym of Spinocalanus spinosus.
Bode & al. (2017, p.612) underline that the high morphological similarities explain, why species initially described as S. stellatus and S. longispinus are currently all synonymised with S. horridus.
