Distribution map of Damkaeria bicornuta by geographical zones
|
| | | | | | | Loc: | | | Antarct. (E Weddell Sea: off Vestkapp) | | | | N: | 1 | | | | Lg.: | | | (957) F: 0,79-0,89; M: 0,68-0,70; {F: 0,79-0,89; M: 0,68-0,70} | | | | Rem.: | epibenthic (depth: 1983 m).
Schulz (2004, p.206) points to the peculiar wing-like horn-shaped extensions on the genital segment are reminiscent of similar but only convergently developed structures described for the females of two species of the genus Prodisco (family Discoidae). It is unclear what function these lateral protuberances might serve. | | | Last update : 03/01/2015 | |
