Question

which animal have a long arm?

Answer 1

Here is your answer

Octopus have a long arm.

Answer 2

Gibbons. Their arms are incredibly long compared to their legs. They use them to swing with ease through the tree branches. Because gibbons are afraid of the water they will use one of their long arms to hold onto a branch and the other to carefully scoop up water while staying as far away as possible. These large arms are useless when the gibbon is on the ground. They simply raise their arms above their heads and keep them there because they don’t know what to do with them.
