Distribution map of Cornucalanus simplex by geographical zones
|
| | | | | | | | | | Loc: | | | Antarct. (S Atlant., SW Pacif., Ross Sea), off Ghana, off Cape Finisterre, Azores, W Indian, Indonesia-Malaysia, N Chile | | | | N: | 8 | | | | Lg.: | | | (1) F: 6,3; (5) F: 5; (15) F: 6,41; 6,35; {F: 5,00-6,41} | | | | Rem.: | Bathypelagic.
Sampling depth (Antarct.) : 0-2000 m.
This species is similar to C. robustus but can be distinguished from it.
For Vervoort (1957, p.92) this species has a rounded head, without any trace of a cephalic spine. The curved claws on the terminal portion of Mxp both have a longitudinal row of fine, closely packed spinules and thus are quite different from those met with in C. chelifer. The postero-lateral thoracic border is broadly triangular and minutely pointed; the small point is obtuse. P5 of both sides are 3-segmented; the basal segments of each sides are sparingly haired and fused to some extent; the free terminal segments are densely haired; the apical segment has 3 spinules, 1 at the apex and 2 subapical spines of unequal length on each side of the apical spine. | | | Last update : 02/01/2015 | |
