1. Presence of a soft and unsegmented body: Mollusks have a soft body that is typically encased in a hard shell (although some species, like slugs and nudibranchs, may lack a shell).
2. Bilaterally symmetrical body plan: Mollusks have a body plan that can be divided equally into two mirror-image halves along a central axis.
3. Mantle: Mollusks have a fleshy fold of tissue called the mantle, which surrounds their internal organs and secretes the shell (if present).
4. Radula: Most mollusks possess a specialized feeding organ called a radula, which is a rasping tongue-like structure used for scraping and obtaining food.
5. Presence of a foot: Mollusks typically have a muscular foot, which is used for locomotion, attachment, and burrowing.
6. Open circulatory system: Mollusks have an open circulatory system, meaning that their blood (hemolymph) bathes the organs directly rather than being confined to a network of blood vessels.
7. Coelom: Mollusks have a well-developed coelom, which is a fluid-filled body cavity located between the body wall and the internal organs.
8. Variety of external structures: Mollusks display a wide range of external structures, including different types of shells, tentacles, siphons, and appendages, depending on the specific class or species.
9. Variety of feeding habits: Mollusks exhibit diverse feeding habits, including filter feeding (e.g. clams), grazing on algae (e.g. snails), predation (e.g. octopuses), and parasitism (e.g. parasitic snails).
10. Variety of habitats: Mollusks can be found in various habitats, including marine, freshwater, and terrestrial environments, occupying habitats as diverse as oceans, lakes, rivers, and even land.
