brisaster.antarcticus: Presence-only records of the echinoid Brisaster antarcticus (Kerguelen Plateau)

Description

Dataset that contains the presence records of the echinoid species Brisaster antarcticus reported from several oceanographic campaigns including RV Marion Dufresne MD03 1974 & MD04 1975, POKER 2 (2010) and PROTEKER 2013, 2014, 2015. Brisaster antarcticus (Doderlein 1906) is distributed from 3.5 to 75.6W and -53.35 to -45.95S in the Southern Ocean. The species is mainly found around Kerguelen and Crozet Islands. Brisaster antarcticus commonly lives from 100 to 600 meters depth. It is a detrivorous species for which reproduction includes dispersal (David et al. 2005).

See Guillaumot et al. (2016) for more details.
