Animals in the rainforest have adapted to live in and around the lush vegetation of the region. Some of them have developed camouflage techniques while others have developed bright colors to ward off predators.
Arboreal Adaptations Many rainforest animals have adapted to live in the tall trees of the regions. Sloths have adapted to the rainforest by moving into the trees. Living high in the canopy, these slow-moving mammals mainly eat tree leaves. They use their strong toes to climb and hold on to branches. Spider monkeys have also adapted to live at the top of the canopy, and they use their long arms to swing from branch to branch. Living high in the trees helps these animals avoid predators, and they face lower competition over food and other resources because not all animals can get to the tops of the trees.
Animal Camouflage Many rainforest animals use camouflage as an adaptation to keep them safe from predators. They have developed colors and patterns that blend in well with the leaf litter on the ground or the green color of the leaves and moss on the trees. Many species of snakes and lizards use camouflage. Sloths also use camouflage because they move so slowly that moss grows on their fur, allowing them to blend in with the trees. Some species of grasshoppers have developed near transparent coloring so they can blend into almost any surroundings.
Animals with Bright Warning Colors On the opposite end of the spectrum, many animals develop very bright coloring and distinct markings to scare away predators. This is common in many types of reptiles including tree frogs, and many types of insects including various species of butterflies and beetles. These animals typically have bright colors including red, green, blue and yellow. These bright colors scare away predators by making them think that they are poisonous. Some brightly colored rainforest animals, such as certain species of dart frogs, are actually poisonous. However, others simply imitate the coloration of poisonous animals in order to deter predators.
Size as an adaptation Some rainforest animals have adapted to be fairly small in comparison to animals in other regions. The largest cat in the rainforest is the jaguar, which weighs slightly more than 200 pounds and reaches up to 6 feet long. This smaller stature allows the jaguar to quickly and move between the dense foliage and large trees easily, whereas larger cats may find this difficult. Many types of snakes, however, have adapted to be very large because they have the ability to slither along the ground between trees. Some can even reach lengths of up to 30 feet and weigh as much as 500 pounds.
Some rainforest animals have adapted to hunt during the night instead of the day. Animals like the flying fox bat and Wallace's flying frog face less competition from animals, such as birds and diurnal reptiles, when they hunt at night. Many species of insects are also nocturnal, so this gives insectivorous predators an opportunity to hunt. These nocturnal animals have developed better eyesight in the dark than many other types of animals.
