Much like our own finger nails a snail’s shell forms part of its body. … If this shell becomes significantly broken then the snail will die.

Most species of land snail are annual, others are known to live 2 or 3 years, but some of the larger species may live over 10 years in the wild. For instance, 10-year old individuals of the Roman snail Helix pomatia are probably not uncommon in natural populations.

The snails’ blood not only serves to transport respiratory gases and nutrients. … Most snails’ blood pigment is haemocyanin. Contrary to haemoglobin, used by vertebrates, haemocyanin works on a complex with copper as oxygen binding atom. That is why snail blood in its oxidised state appears pale blue in colour.
