There are many different types of monkeys and apes that are confusing to figure out which species it belongs to. The orangutan is known for doing acrobats and swinging effortlessly from tree to tree and upside down. Due to their long arms and legs and their flexibility, they can do these acrobats with ease. Orangutans do other unusual things like talking. These animals communicate using noises.
Some of the sounds are long and some are short. They mean different things depending on the length of the sound. A long sound usually mean attention whereas the short sounds are to produce fear. Orangutans also will blow kisses. A human may think that this means they love someone or something, but it actually means they are frustrated with something.
