Describe the integument of a frog. What is responsible for skin color in frogs?

The coloration of frogs is used for a defense. Skin color us produced by special pigment cells,(chromataphores), located mainly in the dermis. Three types of chromataphores: uppermost in the dermis are xanthaphores(yellow, orange, or red), iridophores (silvery-light reflecting pigment), and melanophores (black or brown). The inner layer of epidermis gives rise to two types of integumentary glands that grow into the lose dermal tissues below.
