Answer: They live in similar environments and have analogous structures adapted to them.
Explanation: This is because they have similar habitats, in this case tree tops. Animals develop similar structures or features that enable them to adapt to and interact effectively with their environment. This is called structural adaptations. They show these adaptations in forms and functions in their environments. These structural adaptations are used by the organisms for functions such as getting food, protection and defence, reproduction, regulation of body temperature and conservation of water.
