Every animal is able to live and survive in a particular environment- that just is how they are made and that is why you would come across different types of animals in, say, the Arctic, and different types of animals in a tropical rain forest. A tropical rainforest generally tends to be very humid and these places attract a variety of animals and insects. You would probably come across the most variable types of animals in a tropical rainforest as opposed to other places because the climate and temperature here is very moist and humid in these regions.
You will see quite a few chameleons in these forests. These types of animals in a tropical rainforest tend to be very good at camouflaging themselves. They have long tongue which allows them to shoot out the tongue, reach a fly or an insect, and they then eat it. These types of animals in a tropical rain forest are usually able to change their colors according to the type of surface they are sitting on. That is why you may never be able to see them on the trees’ trunks or on leaves- they are excellent at camouflage.
Tigers are also types of animals in a rainforest but these animals are generally very silent and you won’t be able to see them unless they attack you because they tend to hide from anything that seems like a threat to them or their territory and they then, attack the threat. These types of animals in a tropical rainforest tend to be excellent at killing prey and they are also good at hunting for other sorts of food. It is best to stay away from these types of animals in a tropical rainforest unless you have a tranquilizer with you!
Another of the various types of animals in a tropical rainforest is the crocodile. You would generally find these in rainforests where ponds can be found and they tend to stay in water for short periods of time and they then, wander off until they come back to the waters later on. These types of animals in a tropical rainforest are very unpredictable. You never know how they would react and they do not take too kindly to threats either. Crocodiles are known to swallow people whole! These types of animals in a tropical rainforest are best dealt with if you have a harpoon or equipment that would allow you to protect yourself.
The most dangerous types of animals in a tropical rainforest are snakes. These guys do not hide or wait for you- they just slither and come straight at you. You know those movies that they make about snakes? That is usually how snakes do tend to act (without the special effects) and one of the most common types of snakes you would find in a tropical rainforest is the anaconda. These snakes are thick and would literally squeeze their prey to death and are known to kill many big animals and humans too.
