Description

Dataset that contains the presence of the echinoid species Brisaster antarcticus reported on the Kerguelen Plateau (63/81W; -46/-56S) during the campaigns of the RV Marion Dufresne MD03 1974 & MD04 1975, POKER 2 (2010) campaigns and the program 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. (submitted) for more details.
