Sea creatures, such as mollusks, live in their shells for protection and support. The shell serves as a hard outer covering that defends against predators and environmental hazards. Inside, the creature's soft body is protected while it can still access food and oxygen from the surrounding water through specialized structures. Additionally, many mollusks can produce and repair their shells as needed, allowing them to adapt to their environment.

Sea creatures with shells have evolved various adaptations to protect themselves from predators in their marine environment. These adaptations include hard shells that provide physical protection, camouflage to blend in with their surroundings, and the ability to retreat into their shells when threatened. Some species also have spines or other deterrents to ward off potential predators. Overall, these adaptations help sea creatures with shells survive and thrive in their underwater habitats.
