Question

1. How do amphibians breathe under water?
2. What is the advantage of muscular limbs in arboreal animals?​

Answer 1

1. Most Amphibians breathe through lungs and their skin. Tadpoles and some aquatic amphibians have gills like fish that they use to breathe. There are a few amphibians that do not have lungs and only breathe through their skin.
2. Arboreal animals frequently have elongated limbs that help them cross gaps, reach fruit or other resources, test the firmness of support ahead, and him some cases, to brachiate. However, some species of lizard have reduced limb size that helps them avoid limb movement being ostructed by imphing branches.
