Orangutan
Orangutans are the species of great apes that are mostly found in rainforests. Orangutans prove themselves as intelligent animals by using various tools found in their surroundings. They can use a single tool in many tasks, for example, they use leaves to make an umbrella for protection from rain, to make gloves for protection of their hands in spiky plants, and for making a primitive phone to enhance their listening ability.
Orangutans also make good use of sticks for drilling in tree barks to catch the tasty insects, and to measure the depth of water in streams. Furthermore, they have also been spotted to make utensils from branches and leaves of the various trees.
