As the snail grows, the shell increases in size by growing around the first whorl – and around, and around, until the snail has reached its adult size. Different species of snails have different numbers of whorls. The snail moves about by means of a large, muscular structure called a foot. Waves of muscular contractions and expansions enable ...

When touched on its soft body, the snail can sense whether there is danger and will retract into its shell, if necessary. Statocysts: Land snail statocysts are hollow balloons surrounded by cells with a ciliated (hairy) interior that are filled with a lymphatic fluid.
Where does oxygen come from in snails?
Inside the lung, which is a region of tissue where gas exchange occurs, the oxygen is picked up by the blood, and carbon dioxide is emitted – again, just like human respiration. The mantle is a fold of skin that surrounds the snail’s internal organs.

Do snails have a spinal cord?
Snails like other invertebrates do not have a spinal cord nor one single brain. Instead they have a set of ganglia (groupings of neurons) that distribute the control of the various parts of the snail. In Pulmonates, the ganglia are arranged in a circle around the digestive system.
How many bones are there in the skeletal system?
The skeletal system in the body is made up of 206 bones that are arranged in the axial skeletal system and the appendicular skeletal system.

How many bones are in the appendicular skeleton?
The appendicular skeleton is made up of 126 bones that include the upper limbs, lower limbs, pelvic girdle and pectoral (shoulder) girdle. There are three types of muscle tissue (more than 600 muscles) in the body including skeletal muscle, cardiac muscle and smooth muscle.
