It's all greek(and latin)to me or what do those snail names mean?

Have you ever wondered why snails have the names that they have?Why is a Moss snail called like that and how did Helix apersa came by its name?Snail names can have different sources.Sometimes they are derived from their appearance or from the habitat they live in.In other examples they are named after their discoverers or in honor of a person. In most of the cases latin or greek names are used in naming snail species. I will give examples of all these possibilities.

Appearance Let's take one of the most common landsnails:Helix aspersa. Helix is greek for spiral;aspersus is latin for speckled. Another example:Strobilops labyrinthica Strobilos ops is greek for having the appearance of a pine cone;labyrinthus is a latin word for a labyrinth.(In this case refering to the lamellae in the aperture)

Habitat The most common garden snail is probably Cepaea nemoralis and got its name like this: Cepaea is derived from the greek word for garden:kepaios;nemoralis comes from the latin meaning inhabiting woods The Florida Apple snail,Pomacea paludosa,is named very aptly: Pomum the latin word for apple;palus also latin for swamp. An apple living in a swamp,to put it simply. Here is another one:Lymnaea stagnalis: limnaios is greek for pertaining to marshes;stagnum is latin for pool or swamp.

People Quite a few snail species are named after malacologists or other people. For example: Mesodon sayanus after Thomas Say,Stenotrema leai after Isaac Lea,Lioplax pilsbryi after H.A Pilsbry,and Cochlodinella poeyana after Felipe Poey.
