The cave is the residence of many night creatures. Typically, there are 18 types of bats with the amount of thousands, which covers the vast number of national park of Ba Be. They often run in the twilight and dawn time.
There are three types of bat, which are important in pollination, and distribution of the seed. The bats, which eat insects, also help with protecting the local crops from many harmful insects. However, the noise for visitors and bothering for local people to gather its dung are affecting the down number of bats.
