Snails are poikilotherms - cold blooded. That is they do not generate appreciable amounts of heat internally, having a low metabolic rate, and their body temperature passively follows their environment. When extended out of their shell they loose some heat as water evaporates from them (as long as their surroundings are less than 100% humid) so they can have a body temperature a bit less than ambient. On the other hand, in desert conditions and full sun, they can be tens of degrees hotter than the air (and definitely not extended for long if they're going to survive).

The purpose of a snail carrying its body inside its shell is for protection and to regulate its body's moisture and temperature.
Snail are cold blooded, as their body temperature is controlled via external means.
A reptile maintains an internal temperature by using exothermic methods of controlling its body temperature.
a snail has a bilteral body system.

It is secreted by a portion of the snail body called the mantle.
a snail has abreathing hole on the side of its body, the slugs also have the same thing
when a snail is born it has a shell, and its actual body is still growing in the shell.
The mouth.

To safely introduce a snail to a tank with betta fish, acclimate the snail to the tank water temperature, ensure the tank has enough hiding spots for the snail, and monitor the betta's behavior towards the snail to prevent any aggression.
