What feature protects the bodies of animals like lobsters?

The exoskeleton is a vital feature that protects the bodies of animals such as lobsters. This hard outer shell serves as a protective barrier against environmental hazards, predators, and physical damage. Unlike an internal skeleton, the exoskeleton is external and composed primarily of chitin, making it both strong and lightweight, which allows lobsters to move effectively in their aquatic environments.

Additionally, the exoskeleton plays an important role in locomotion, as it provides attachment points for muscles that facilitate movement. As lobsters grow, they molt their exoskeleton to accommodate their increasing size, showcasing the dynamic nature of this protective structure. Overall, the exoskeleton is essential not only for protection but also for supporting the lifestyle and movement of lobsters in their natural habitat.
