What is the differences between snail and turtle?

A snail belongs to the molluscan class and has no bones or limbs.

Turtles are reptile and have much harder, larger and flatter shells. Turtles also have limbs in the form of flippers to help move easily through water in the oceans where they live. Snail's are herbavoires and eat a variety of vegetation and fruit on land, but turtles have a diet of either sea grass and algae or sponge's, shrimps and squid, purely depending on the species and location.
