A large group of soft-bodied animals that often have shells, including snails, clams, oysters, and octopuses. They are found in marine, freshwater, and terrestrial environments worldwide.
From Latin 'molluscus' meaning 'soft', referring to their soft bodies. The term was adopted into scientific classification in the 18th century to group these diverse soft-bodied animals.
Mollusks are incredibly diverse - from tiny snails to giant squid with eyes the size of dinner plates! They've mastered every environment and include some of the most intelligent invertebrates, with octopuses demonstrating problem-solving skills that rival those of vertebrates.
