The epidermis usually consists of 30 layers of cells that function as a waterproof layer. The outermost cells of the epidermal layer are often peeled off; the innermost epidermis often divides and the sapling cells are pushed upward (outwards). The middle part, the dermis, has a thickness of 15-40 times that of the epidermis. The dermis consists of various components such as blood vessels and glands. The hypodermis is composed of adipose tissue and functions to store fat, resist impact, and insulation. The thickness of this layer varies from species to species.
