The Secret Life of Deep Sea Symbiosis with Dr. Shana Goffredi

How deep sea worms eat without a mouth is just one of the astonishing discoveries in this episode with microbial symbiosis expert Dr. Shana Goffredi. We dive into the strange and beautiful world of methane seeps and hydrothermal vents, where animals form life-saving partnerships with chemo synthesizing bacteria. From feather duster worms powered by natural gas to mixotrophic anemones thriving in volcanic vents, learn how cooperation fuels entire deep sea ecosystems — and helps prevent methane from reaching our atmosphere. These microscopic alliances are transforming how we understand evolution, resilience, and oceanic carbon cycling.
