On the biogeography of Cumacea (Crustacea, Malacostraca). A comparison between South America, the Subantarctic Islands and Antarctica: present state of the art
Cumacea (Crustacea) were collected during the Joint Magellan expedition in November 1994, by means of an epibenthic sledge from RV Victor Hensen. The cumaceans were well represented, the second abundant order after the amphipods, among the other Peracarida in depth ranges between 25 and 665 m. Twent...
