Hard-shelled

Describing an animal, object, or entity that possesses a rigid, protective outer covering or shell. This outer layer is typically composed of a mineralized substance (like calcium carbonate in crustaceans), a hardened protein, or a similar material, providing defense against predators, environmental hazards, and physical damage. It often serves as a primary barrier for internal organs and can play a role in support and structure. This characteristic can influence the animal's behavior, mobility, and habitat preference. The term can also be applied metaphorically to describe individuals with a tough or unyielding personality.
