Amazing Antarctic Asteroids

An interactive guide to the starfish of the Ross Sea.

The floor of the Ross Sea region is covered in ice for much of the year, but many benthic creatures live and thrive there. For example, did you know that there are over 35 species of asteroid (starfish or sea stars) that occur in this region of Antarctica?

The common Antarctic asteroid species can now be found discovered and identified in the field with Amazing Antarctic Asteroids, a fully illustrated, interactive and downloadable pdf with high-quality images of the animals in life.

Just click on an image in the morphology index and you will be taken to a species page packed with information, beautiful images, and icons to simplify identification. This guide will be useful to expedition staff, ice divers or fisheries observers who are lucky enough to visit this amazing region.
