Amphibian is a group of cold-blooded vertebrates that are capable of exploiting both aquatic and terrestrial habitats. The skin has different cryptic colors which allow them the mechanism of camouflage. Most of the amphibians have moist skin and thus rely heavily on cutaneous respiration. As compared to reptiles, amphibians have smooth skin. Shortly after the first reptiles, two branches split off, one leading to the Anapsids, which did not develop holes in their skulls.
