How do reptiles get their skin color?

In general, reptiles have two sets of cells that produce color, the melanocytes and the chromatophores: Melanocytes are present throughout the basal layers of the epidermis. During the skin-renewal phase of epidermal growth, the melanocytes send pseudopodia into the melanin-bearing keratocytes to transfer the melanin to the new cells.

When insects molt do they shed their exoskeleton?

When Insects Molt. After egg hatches, the immature insect feeds and grows. Its exoskeleton is like a shell. Eventually, the larva or nymph must shed its unyielding overcoat to continue its development. The exoskeleton which serves as its external backbone is used for protection and support.

What is the difference between moulting in insects and reptiles?

In the case of insects, no such substance is secreted. Also, in both groups moulting always involves the growth of the animal, which does not feed during the process. Insects and snakes shed the old layer completely, while the rest of reptiles (turtles, lizards, and crocodiles) do it in parts.

What is metamorphosis and molting in animals?

Metamorphosis: Metamorphosis occurs in cnidarians, insects, crustaceans, mollusks, and animals such as fish, amphibians, echinoderms and all chordates. Molting: Molting mainly refers to the shed of the exoskeleton in insects.

Many different kinds of reptiles change color to one degree or another. Many change color to communicate with other members of their species, others change color only during breeding season, some change color as they age, and a rare few change color for camouflage. Some specific examples:

What is the function of the epidermis in snakes?

This layer mainly stores fat. Molting is common, and results in the entire outer layer of epidermis being lost. The skin of a snake is a physically protective layer. It helps prevent injury, prevents drying out, and helps snakes to minimize friction.

Do turtles shed skin in pieces?
