How are snail and octopuses are different?

Snails and octopuses differ significantly in their anatomy and habitat. Snails are mollusks with a hard, spiral shell and primarily move using a muscular foot, while octopuses are cephalopods known for their soft bodies, lack of a shell, and highly developed nervous systems. Additionally, octopuses are intelligent and exhibit complex behaviors, whereas snails have simpler nervous systems and behaviors. Their environments also differ, with snails often found on land or in freshwater, while octopuses inhabit marine environments.
