DENDROLOGY

Detailed explanation-1: -All members of Amphibia are cold-blooded. Frogs, toads, salamanders, and caecilians all need to utilize the sun and shade balance to regulate their internal temperature. Due to the habitat of most amphibians, this typically isn’t a difficult task.

Detailed explanation-2: -While many amphibians, including frogs, salamanders and caecilians, have smooth skin, most toads have bumpy bodies covered with raised glands, some of which produce toxic secretions. But no amphibians have scales.

Detailed explanation-3: -How do amphibians breathe? 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).
