I deliberately drove more than 500 kilometers to see the glowing worms. The cave itself is not big, it is well protected. The small group is brought in by the guide, walked for a while, and opened a section of the light, introduced the meticulous, the cause, recent events such as the flooded water level, the newly washed out marine life fossils, It is close to the ancient past in southern China, so the geological is similar. The estimated fineness of the growing rock column is only 3-5mm, but the length is more than 1m to 2m. He also explained that Tasmania is geologically stable, with few and small earthquakes. Seeing the cave spider, the glowing worm is not allowed to photograph, although I can use the SLR long exposure without turning on the flash, but he is still not allowed, which is estimated to have commercial protection in the meaning of inside.
