(central equatorial), Cape Verde Is., Mauritania, off Morocco-Mauritania, Canary Is., SW Atlant., off Amazon, Caribbean Sea, Caribbean Colombia, G. of Mexico, Florida, Sargasso Sea, off Bermuda: Station "S" (32°10'N, 64°30'W), Azores, off Portugal, off W Cape Finisterre, Bay of Biscay, off W Scotland, S Strait of Davis (in Jespersen, 1934), Baie Ibéro-marocaine, Medit.

The mean female size is 1.913 mm (n = 39; SD = 2029), and the mean male size is 1.696 mm (n = 14; SD = 0.2146). The size ratio (male : female) is approximately 0.88. | | | | Rem.: | epi- bathypelagic. Sargasso Sea: 500-1500 m. 0-217 m at Station T-1 (Tori Is, E Japan). Abundant almost exclusively in the north Aegean Sea deeper than 300 m (Siokou & al., 2013).
For Rose (1937, p.165) the male resembles C. poppei female by the appendage structures, with dte usual sexual differences between sex. It is probably the male of C. poppei.
After Markhaseva (1996, p.123) the exopod female of P2 is 3-segmented (in original material the separation between segments 1 and 2 incomplete) and endopod 1-segmented (with traces of separation).
R. Stephen: Data sheets of NIO, Kochi, India (on line).
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 4 corresponding to small filter feeding herbivorous and mixed feeding omnivorous (mostly broadcasters). | | | Last update : 02/04/2020 | |
