What are the three differences between an animal that lives in the water and an animal that lives near the mountains?
The three differences between an animal that lives in the water and an animal that lives near the mountains are as follows:an animal that lives in the water may be asymmetrical, radially symmetrical or bilaterally symmetrical with streamlined body, whereas an animal that lives near the mountains will always show bilateral symmetry.an animal that lives in the water may be either cold-blooded or warm-blooded, but an animal that lives near the mountains will always be warm-blooded.an animal that lives in the water may be covered with spicules, scales or just tough skin, while an animal that lives near the mountains will always have a thick hide of hair or fur.
