Waitomo Glowworm Caves, Waitomo, North Island, New Zealand

Biology
The most renowned animal in the cave is the glowworm Arachnocampa luminosa. There are several small underwater lakes that were created by freshwater creeks or brooks.
The walls of the caves are covered with a variety of fungi including the cave flower (a distant relation to the genus Pleurotus) that is actually a mushroom-like fungus. The most common animals in the caves are insects. This includes albino cave ants, giant crickets, and of course the glowworms.
