What is the scientific name for slugs?

I can鈥檛 find any information on slugs. What are they? They leave slime trails allover my porch, and at night, they climb-up the side of my house.

What is the scientific name for slugs?
Slugs are gastropods like snails, and belong to phylum Mollusca along with clams, mussels, squids, octopi and other less known invertebrates.


The gastropods are asymmetrical and have a single shell that usually coils in a spiral, but slugs have a very reduced shell or lack it altogether.


Slugs are among the few terrestrial mollusks; they have a lung instead of gills like their aquatic relatives (the lung opening is lateral and the lung is within the "saddle-like" part of its dorsum). This is Limax, a common slug genus:

Here's a key to slugs of Florida (including some South American species). It has good drawings with labeled body parts:

In addition, there are also "sea slugs". These Gastropods have gills posteriorly on their dorsum, and swim and crawl rather gracefully. They are brightly colored and look like spectacular pieces of candy:

Slugs are gastropod molluscs without shells or with very small internal shells, in contrast to snails, which have a prominent coiled shell. The loss or reduction of the shell is a derived character, and the same basic body design has independently evolved several times, making slugs a polyphyletic group. Although they undergo torsion (180 degree twisting of internal organs) during development, their bodies are streamlined and worm-like, and so show little external evidence of it. Slugs include both marine and terrestrial species. The main group of marine or sea slugs are the nudibranchs. However, the ecological information in the article below applies mainly to land slugs.





The soft, slimy bodies of slugs are prone to desiccation, so land-living slugs are confined to moist environments.





Slug genitalia are also some of the most prodigious in the world. Ariolimax dolichophallus, a species of banana slug (from Greek dolicho-, long and Latin phallus, penis) has the largest penis-to-body length ratio of any animal. The record-holding specimen had a body length of 6 inches, with a phallus length of 32.5 inches, well over five times the body length.

Reply:i dont they have a scientific name, because a slug is technically a snail without a shell. No wait i think their scientific name is Gastropoda.
Reply:Slugs are mollusks like snails and clams. They are a snail without a shell. To control, spread diatomacious earth (crushed diatoms) or set out stail beer in very low dishes.
