Answers
Answer:
Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (If they get too dry, they cannot breathe and will die). ... Tadpoles and some aquatic amphibians have gills like fish that they use to breathe.
Arboreal animals frequently have elongated limbs that help them cross gaps, reach fruit or other resources, test the firmness of support ahead, and in some cases, to brachiate. However, some species of lizard have reduced limb size that helps them avoid limb movement being obstructed by impinging branches.
Fully prehensile tails can be used like a hand to hold onto objects and to help arboreal creatures find and eat food while in the trees, like the African tree pangolin pictured. Partially prehensile tails are often used to anchor an animal's body while it dangles from a branch or as an aid for climbing.
Aquatic animals lives only in water and dies if it comes in contact with land but amphibians are animals which can live both in water and land. example of aquatic animal is fish. example of amphibian is frog.
