Luminescence. It occurs in the forest, in the ocean, and of course, in space...but did you know luminescence also appears in some of the world's caves? The videos below show glowworms in New Zealand's Waitomo Glowworm Caves. These critters cling to the cave's ceiling and secrete slime. The glowing mucous dangles, attracting flying insects. Once the insect is trapped in the sticky slime, the worm withdraws the mucous and consumes its prey.
