Rem.: epipelagic.
For Greenwood (1977, p.63 ) this species, like C. furcatus, is a warm water epiplanktonic form found in both neritic and oceanic waters; the Moreton bay specimens generally were taken in conditions of high salinity (36.69-32.20 p.1000! and temperature (27.0-15.3°C). Although never a dominant, the relatively large size makes their biomass significant in the plankton. After Mulyadi (2004, p.131) this species resembles C. kroyeri.
For El-Sherbiny & Al-Aidaroos (2015, p.407) C. orsinii constitutes with C. halinus and C. mohamedi a ''orsinii'' species-group, members of which share the following features: 1- posterior corners of both sexes weakly pointed; 2- P1 to P3 with 2-segmented endopods, whilst 3-segmented endopods are retained on legs P4 and P5; 3- female P5 possess a relatively short medial process on the 2nd exopodal segment with bilateral serration along the distal part of the lateral margin; 4- male left P5 consists of 2-segmented exopod (ancestral segments 2 and 3 fused), with the 2nd segment being fused to a relatively long bilaterally serrated distal spine; 5- male right P5 with 2nd exopodal segment has short seta at the distolateral corner and relatively short medial process slightly increasing the length of the 2nd exopodal segment; 6- male right P5 with 2nd exopodal segment curved and armed with a slender seta medially close to the basal articulation.
