According to the Seoul National University College of Veterinary Medicine, the integumentary system of the frog includes the skin, hair follicles, sweat and sebaceous glands, digital organs and glands. The integumentary system’s main purpose is to provide protection from disease, viruses and from physical damage.
This system also protects a frog from dehydration, overheating and even freezing. The epidermis has four distinct layers and the thickness can vary depending on the area of the body, which can protect the organs inside. The integumentary system helps provide the frog with camouflage from predators and helps him to stay moist while he is on land. It can also help a frog breathe while he is under water.
