Raising snails.Part I

Snail features

Snail is a gastropod mollusk that belongs to the family of Helicidae. It moves by means of a locomotive system called foot. It has an enclosing spiral shell.
The body is formed by foot and head. In the head there is a pair of major tentacles that take in charge of the touch sense, and a pair of minor tentacles that take in charge of smell.

Snails move slowly, around 3 inches per minute. It has an average life expectancy of 5 years.

There are species of snails like Helix Pomatia that suffer a process of operculization that protect them from low winter temperatures.
In summer, they present the phenomenon of stiving and in winter they suffer hibernation. They are both strategies of the snail to resists unfavorable atmospheric conditions.

To tell the difference between species we can consider color, the shape of peristome (region around the mouth), position, opening shape and the shape of the shell.
