Asteroidea of the southern tip of South America, including Namuncurá Marine Protected Area at Burdwood Bank and Tierra del Fuego Province, Argentina
In benthic communities, echinoderms are dominant in terms of abundance and diversity, and Asteroidea play an important role in the structure of communities. In the present study, Asteroidea were sampled in the recently created Namuncurá Marine Protected Area (N MPA) at Burdwood Bank (which has an av...

In benthic communities, echinoderms are dominant in terms of abundance and diversity, and Asteroidea play an important role in the structure of communities. In the present study, Asteroidea were sampled in the recently created Namuncurá Marine Protected Area (N MPA) at Burdwood Bank (which has an average of 50–200 m depth and is delimited by abrupt slopes), the surrounding shelf break and Tierra del Fuego Province, Argentina, at 24 stations at different depths and seabeds on board the oceanographic vessel ARA “Puerto Deseado.” A total of 32 Asteroidea species were identified. The bathymetric ranges were extended for two of them, and the geographic distribution was updated for seven of them, this being their first record in the N MPA.
