Nudibranchs: The Ocean’s Living Rainbows


October 8, 2025
LIVE at 3:00 PM ET / 2:00 PM CT / 1:00 PM MT / 12:00 PM PT


Presented by Melissa Silva

Brilliantly colored, strangely shaped and endlessly fascinating, nudibranchs (a type of sea slug) are some of the ocean’s most extraordinary creatures. These tiny mollusks thrive in kelp forests, coral reefs and other underwater habitats. Expedition Leader Melissa Silva introduces us to their world, from their specialized diets to their role as indicators of ecosystem health. Discover how these "living rainbows” feed on sponges, anemones and other invertebrates -- sometimes even stealing their toxins or stinging cells to use for their own defense.
