Slug

Description:

Slugs and snails are not insects but mollusks* related to oysters, clams, and other shellfish, and characteristically have soft, unsegmented bodies, usually protected with a hard calcareous shell. A slug is more or less a snail without a shell, or with a shell reduced and located internally.Most slugs live underground and the ones that can be seen feeding above ground are only approximately 5% of the total slug population.

Habitat:

Cool weather, rain and fog is the best weather for slugs because since they don’t have an outer shell to protect them, they may dry out in dry and warm weather. When the weather is warm and dry slugs will try and find a cool, dark and damp area to hide in. However if there is a long dry spell then slugs will encase themselves in a papery cocoon-like structure and attach themselves to a wall or a tree and wait it out. Moist climates.

Notes:

I guess they plant material.
