A Slug’s Life

At the Maritime Aquarium in Norwalk, Connecticut, nudibranchs have become storytellers for an issue facing our oceans that is difficult to understand yet imperative to know about: global climate change. The aquarium has taken a unique approach to educate the public on this global threat. Their new exhibit, A Slug’s Life: Facing the Climate Endgame, showcases the adored mollusk and runs through Sept. 6, 2021. The exhibit’s specific intent is to help guests understand the warnings that changing slug populations provide about the health of their habitats.
