Since the end of the last century, successive expeditions have provided information on the main characteristics of antarctic marine benthos, such as the low diversity of higher taxa, the high degree of endemism, gigantism, or particular developmental types (Dell 1972; Picken 1980; White 1984; Dayton 1990; Gutt 1991; Arntz et al.
