Eos @eos.org · 13/09/2026Here's more evidence that caves and karst are extremely cool: This bioluminescence in a limestone karst cave in Australia's Dorrigo National Park. These gnat larvae produce luminous adhesive liquid droplets, which attract and trap insects to provide a food source for the gnats. 140
