What are 3 animals in the son doong?

While Son Doong cave is a fascinating and beautiful place, it's not known to be home to a large variety of animal life. This is due to the cave's darkness and limited food sources. However, some animals have been found inside:

1. Bats: Bats are common cave inhabitants and likely thrive in Son Doong's darkness.

2. Insects: Various insects, such as spiders and beetles, can be found in the cave's damp and humid environment.

3. Snakes: Some species of snakes are also known to inhabit caves, possibly attracted by the presence of bats or other small creatures.

It's important to remember that exploration of Son Doong is limited, and more research is needed to understand the full range of species that live there.
