Squamates are distinguished by their unique overlapping scales made of keratin, which provide protection, reduce water loss, and aid in locomotion. These scales can vary in shape and size among different species, contributing to their remarkable diversity. Another hallmark of squamates is their ability to undergo ecdysis, or skin shedding. This process allows them to remove old, worn-out skin, facilitating growth and helping to rid the animal of parasites.
- Squamates have keratin-based, overlapping scales that protect and aid movement.
- Scale morphology varies widely, contributing to species diversity.
- Ecdysis is the periodic shedding of skin that promotes growth and parasite removal.
Squamates have scales made of keratin, not chitin or calcium carbonate.
Overlapping scales protect the body, minimize water loss, and assist in movement.
Skin shedding helps with growth, removes parasites, and renews the skin.
Ecdysis is the scientific term for skin shedding in squamates.

Conclusion
Squamates are uniquely adapted reptiles whose keratinous scales provide protection and functionality, while their ability to shed skin ensures growth and health.
- Overlapping, keratin-based scales are a hallmark of Squamata.
- Ecdysis (skin shedding) supports growth and parasite removal.
- These adaptations contribute to the remarkable diversity and success of squamates.
