Who's watching out for the creatures at the bottom of the Southern Ocean? Geneticist Professor Melody Clark and ecophysiologist Dr Simon Morley talk about their decades of work understanding the animals who have evolved to survive in the world's coldest waters. From antifreeze fish to nail-varnish-wearing limpets, and from the gut microbiome of sea cucumbers to anti-microbial resistance, Melody takes us on a whistle stop tour of some of the main characters she's been studying in Antarctica. Meanwhile, Simon talks about his journey into studying the marine life around the frozen continent - and what the effect of warming will be on these creatures. He talks about the climate, optimism, and what you can do as an individual to make change. --- Welcome to Antarctica.
