Antarctic fish with antifreeze blood are revealing critical clues about evolution and climate change. In this special crossover episode from South Pole, marine biologist Dr. Jilda Alicia Caccavo from the Institut Pierre Simon Laplace joins us to explore pelagic notothenioids — fish uniquely adapted to the icy waters of the Southern Ocean. Learn how their antifreeze proteins, colorless blood, and genomic traits help them survive extreme conditions, and why their future is under threat as ocean temperatures rise. Dr. Caccavo explains how genomics offers powerful insights into species vulnerability and resilience in a changing climate. If you're fascinated by cold-water biology, marine adaptation, or the impact of climate change on ocean life, this episode is for you.
