Frog skin is amazing! Find out why

1. The skin protects the animal against abrasion and infection from environmental pathogens.
2. Permits the exchange of respiratory gases (oxygen and carbon dioxide).
3. Permits absorption and secretion of electrolyte ions, thereby serving as an adjunct to the kidneys in maintaining correct electrolyte balance.
4. Permits absorption and release of water, thereby serving as an adjunct to the kidneys in maintaining correct water balance or hydrostasis.
5. Permits temperature regulation by lightening (reflecting heat) or darkening (absorbing heat) in some species.
6. Permits the animal to camouflage itself against its background in many species.
7. Brightly colored skins serve to warn potential predators of defensive noxious ore even fatal glandular skin secretions in a number of species.
8. Serves sensory functions: chemoreception, mechanoreception or tactile sensibility; and electrodetection in some fully aquatic species that retain lateral line organs in their skin.
9. Protects against cutaneous external and internal wound infection through the secretion of peptide antibiotics in some species
10. Liberates alarm substances in members of a population when one or more is attacked, thus alerting others to the presence of danger. Other odors associated with larval frogs are said to allow them to recognize their siblings as well as their birthplace.
11. Presence of coloration is designed to permit sexual recognition in some species.
12. Skin distensibility or elasticity permits prodigious feats of jumping, leaping, and even “flying” and landing without injury, often from substantial heights.
