Organisms (like mollusks and corals)

Organisms such as mollusks and corals are diverse animals living in aquatic environments. Mollusks have soft bodies often protected by shells, including snails, clams, and octopuses. They typically have flexible bodies and can move or stay stationary. Corals are marine invertebrates that form large colonies, creating complex reef structures essential for marine life. Both groups have specialized body parts suited to their lifestyles and environments, playing vital roles in ecosystems. They share some common features like soft tissues but differ significantly in form and function, contributing to the richness and biodiversity of ocean habitats.
