Describe tha comparative anatomy of skin of amphibia and mammal
Amphibians have thin, moist skin that helps them breathe. No other group of animals has this special skin. Most amphibians undergo a unique change from larvae to adults, called metamorphosis.
The skin of mammals is constructed of two layers, a superficial nonvascular epidermis and an inner layer, the dermis, or corium. The two layers interlock via fingerlike projections (dermal papillae), consisting of sensitive vascular dermis projecting into the epidermis. The outermost layers of the epidermis are cornified (impregnated with various tough proteins), and their cells are enucleate (lacking cell nuclei).
