Distribution of asteroid genera (Echinodermata) off South Shetland Islands and the Antarctic Peninsula

Frequency and distribution of asteroid genera in the South Shetlands zone are analysed, based on data from 24 Agassiz trawls carried out during the Bentart 95 Survey. Asteroids were collect-ed at more than 90 % of the stations, on all types of bottoms, with richness per station ranging from 0-10 gen...

Description
Summary:Frequency and distribution of asteroid genera in the South Shetlands zone are analysed, based on data from 24 Agassiz trawls carried out during the Bentart 95 Survey. Asteroids were collect-ed at more than 90 % of the stations, on all types of bottoms, with richness per station ranging from 0-10 genera. The specimens belonged to 27 genera and 12 families, with Astropectinidae, Goniasteridae and, above all, Asteriidae having the highest number of representatives (3 and 7
