Allogona profunda (Broad-banded Forestsnail) The formal classification of the land snail, Allogona profunda (Say), is as follows: Domain: Eukarya. Kingdom: Animal. Phylum: Mollusca. Class: Gastropoda.
Snails are effectively slugs that have a strong, spherical shell attached to their back, which they use as a form of protection and compact accommodation. Snails and slugs share a common genetic bodily structure but are classed as two significant species; a slug is not a snail without a shell, as is often misidentified.
