Caves are large, natural holes beneath the surface of the earth. Underground passages and caves are found in rocky landscapes across the world. They are found in areas with a lot of limestone, a common type of rock. They can be created in various ways, but most caves are hollowed out of rock by water. Now we will discuss about living in the cave!

Entrance zone: This zone can be inhabited by a variety of life. Accessible with little sunlight, with a constant temperature but still subject to fluctuation with the weather above ground level. Additionally, certain animals may take shelter in entry zones to sleep, eat, and nest.

Middle zone (Twilight Zone): The twilight zone is the part of a cave that receives a small amount of sunlight since it is not too far from the entrance. This zone is cool and damp, and its temperature is usually constant. Animals that live in the twilight zone are trogloxenes.

Dark zone: The dark zone is the deepest and darkest part of the cave. It is located at the back of the cave and receives no sunlight. As a result, the dark zone is always cool, dark, and its temperature is constant. The dark zone is inhabited by troglobites.

Troglophiles are animals that spend part or all of their live in caves. This animals are able to survive outside the cave in a suitable environment. These include beetles, worms, frogs, salamanders, crickets, and even some crustaceans such as crayfish.


Trogloxenes are the type of cave animal most people are familiar with. They are temporary cave dwellers who are free to go in and out of the cave. Bats, bears, skunks, moths and humans are examples of trogloxenes. Humans might not be consider as trogloxense today, but many thousands of years ago humans used caves as shelters.

There are so many lessons that we can take from various sides of nature. Not only animals, but also all living things have a very significant meaning in the world. Let’s learn about nature and animals with Bali Safari Park!
