Surprisingly, the Southern Ocean around Antarctica is home to a vast array of biodiversity, with around 20,000 species of marine invertebrates and fish living there. Antarctica has been in the polar regions for hundreds of millions of years. The cold but very stable marine conditions and extreme seasonality that we see today have existed in places around Antarctica for at least 20 million years. This long time period has allowed life to produce adaptations not seen elsewhere and to many seem bizarre. This presentation will describe the environment and the adaptations we have described so far and will discuss the how and the why they have come into existence.
