Antarctic and Sub-Antarctic Asteroidea database 2017

Antarctic OBIS Open in mapper Explore occurrences

The present dataset is a compilation of georeferenced occurrences in the Southern Ocean for the asteroids (Echinodermata: Asteroidea). Occurrence data south of 45°S latitude have been mined from various sources together with information regarding the taxonomy, the sampling source and sampling sites when available. Records from 1872 to 2016 have been thoroughly checked to ensure the quality of a dataset which reaches a total of 13,840 occurrences from 4580 unique sampling events. Information regarding the reproductive strategy (brooders vs. broadcasters) of 63 species is also made available. This dataset represents the most exhaustive occurrence database on Antarctic and Sub-Antarctic asteroids.
