Snails are not flammable. They are primarily made up of water and soft tissues. While the shells of some snails are made of calcium carbonate, which can be a bit more flammable than the rest of the snail, the overall composition of a snail makes it highly resistant to burning.

However, it's important to note that:

* Dried snail shells can be flammable. This is because the water content has evaporated, leaving behind the calcium carbonate which can ignite under the right conditions.

* Snails living in flammable environments can be at risk of fire. For instance, a snail in a forest fire could be burned if it cannot escape the flames.

Overall, snails themselves are not flammable, but it's always important to be aware of potential hazards and to treat all living creatures with respect.
