3. Glowworms: These caves got their names because of their residents, glowworms. The illuminating strings that are so attractive are actually larvas of the fungus gnats, an insect that resembles a mosquito, so technically these are not really worms. A chemical known as luciferase is responsible for their light, as these glowworms are bioluminescent and they produce light as this chemical reacts with oxygen and the reason behind this is to attract a mate. These insects are actually carnivores, meaning they eat other smaller insects by setting up mucus traps, however, it is observed that they can go for several weeks without eating. Still, not a worm.

According to experts, the wax-like limestone stalactites are actually the bones and shells of marine life that died and fossilized on the seabed, slowly tuning into rock over the course of millions of years. Then Earth’s tectonic activity pushed New Zealand to the surface and after many years of rain, the area got exposed creating these mesmerizing caves.
