Carte de distribution de Cymbasoma cocoense par zones géographiques

| | | | Loc: | | | NE Pacif. (Chatham Bay, Isla del Coco, Costa Rica) | | | | N: | 1 | | | | Lg.: | | | (1030) F: 1,45-1,67; {F: 1,45-1,67} | | | | Rem.: | For Suarez-Morales & Morales-Ramirez (2009, p.1269) the occurrence of this species is probably endemic, because the extensive and deep oceanic area between the island and the mainland (532 km off the coast of Costa Rica) was expected to constitute an important impediment for dispersal. The dispersive capacity of the adult and larval monstriloids is limited by the presence of their benthic hosts (polychaetes or molluscs), and their relatively short residence time in the water column.
