Snail, turtle and hedgehog coloring game. Snails belong to a group of animals called molluscs and they can be found in gardens, in ponds, in rivers and even in the ocean. Adult turtles can live on either land or water, but spend most of the time in water. Some sea turtles live to be well over 100 years! Hedgehogs are mammals. They have spines everywhere except on their face, bellies, and legs.
