Now, one funny fact about koalas is the fact that they eat mainly during the night, since the temperatures are cooler. Another fun fact is the part where they eat about three hours per day – you can imagine the general idea of it. There are many other reasons based on which koalas only eat the eucalyptus leaves and one of the reasons is that the koalas live high among the tree for protection against the other animals that might mean harm to the koalas. The oil that is on the eucalyptus leaves is poisonous to other animals.
Generally, they are found in the dense forests only. They do not eat anything else except the eucalyptus plants. Somehow, they are also eaten by owls or eagles because they are not having a fighting nature. While they are known for eating the eucalyptus plants, they generally do not eat anything else but if they found anything of their like say, tea leaves, paper bark tree, they eat that also. As per the estimation, one Koala bear can eat up to 200-500 grams of eaves on daily basis.
Thus, Koalas can get these plants easily for their food and also it is possible that they can sleep on bamboo trees by balancing them on it. However, they are rarely found and they are not available in many parts of the world. Because of globalization and ending of plants and forests, their existence is in danger.
