Detailed explanation-1: -The whale shark isn’t only the largest fish in the oceans. It also has the thickest skin of any living creature – in the oceans or on land. Typically around 10 cm (4 in) in thickness, the skin offers vital protection and insulation for the animal.

Detailed explanation-2: -Skin is thickest on the palms and soles of the feet (1.5 mm thick), while the thinnest skin is found on the eyelids and in the postauricular region (0.05 mm thick).

Detailed explanation-3: -A pachyderm is a really big animal with really thick skin, like an elephant or a hippo. If you break this word down to its parts, you see pachy which means thick and derm which means skin. It comes from the Greek, but was first used to describe a class of animals by a French naturalist in 1797.

Detailed explanation-4: -Other fish use collagen like Arapaima does, but the collagen layers in Arapaima scales are thicker than in any other fish species. The scales alone are each as thick as a grain of rice.

Detailed explanation-5: -Frogs have some of the thinnest skin of all vertebrates and with very good reason…. they breathe through it. Their skin has evolved to let oxygen pass through the cells of the epidermis and dermis and into the blood stream and frogs can get up to 20% of the oxygen they need in this way.
