Feeding: Most land snails herbivores and some are a detivores. A garden snail has thousands of tiny teeth. These thousands of tiny teeth are located on a ribbon like tongue and work like a file and rip the food to bits. They eat the little bits of chalk in the rock which they need for their shells.

Respiration:Snails have got a thin skin permeable for water.That means that water snails also can breathe through their skin. Snails originally breathe by gills. The snails' gills look like a double comb, with a stem and feathery protrusions.The absorption of oxygen from the water and the diffusion of carbon dioxide into the water

Internal Transport: Snails have an open circulatory system. Blood flows into internal body cavity called sinuses.
Response :Have a nervous system that coordinates movement and behavior.They have a nerve cord going through their body which lets it to respond to stimuli. They also have muscle which helps with movement.
Reproduction: They mate and lay eggs. Some snails are hermaphrodites, though (have both male and female sexual organs in the same individual), which means that two snails can fertilize each-other.

Excretion:. In terrestrial snails, excretion takes place in a kidney, whose interior surface has been increased by many interior walls called septae. Through their walls filtration of blood flowing through takes place. Terrestrial snails usually excrete urea, containing almost no water.
Movement:To move, snails make a complex series of wave-like movements along their entire body, which propels them forward. Most of a snail's body actually consists of a large foot, and so the part of the body touching the floor is known as the sole.
