The Helicidae, sometimes known as the typical snails, are a taxonomic family of medium sized to large, air-breathing, land snails. In other words, they are small to large terrestrial pulmonate gastropod mollusks.
Well-known species in this family include Helix aspersa the garden snail, and Helix pomatia the "escargot".
Distribution
The family is native to Europe.
However some of the species, such as for example Helix aspersa, have been introduced and become established in numerous different places worldwide.
Many accidental introductions happen because the eggs of most Helicidae are laid in the soil, and they may thus easily travel unnoticed along with landscaping plants.
Shell description
The shells of these snails are mostly rather globular in shape. In some genera, such as Cepaea, the shells are brightly colored and patterned.
