What are the adaptations of shells?

Shells serve various adaptations primarily for protection, camouflage, and buoyancy. The hard exterior provides a barrier against predators and environmental hazards, while intricate patterns and colors can help blend the organism into its surroundings. Additionally, some shells are designed to aid in floating or sinking in water, allowing the organism to maintain optimal positioning within their habitat. These adaptations enhance survival and reproductive success in diverse environments.
