( Deroceras praecox )

The slug family of slugs, also called Kleinschnegel, (lat. Agriolimacidae ) belongs to the order of snails ( Pulmonata ). They represent the largest family of slugs

Features

Most species of the family of slugs are small to medium in size. Specimens of the genera Mesolimax and Krynickillus provide up to 60 mm body length, the longest species dar. The coat is relatively large at the slugs and occupies about a third of the body length. The species of the genus Megalopelte the coat even covers almost the entire surface of the animal. The breathing hole is median or nearly median. The coat directly to the breathing hole is something sublime. The surface of the slugs being covered with a concentrically arranged movable folding. There is still a small bowl plate ( rest of the auger housing ) obtained in the jacket.

The majority of the species preferred eats fresh plant material. The distribution of the family was originally Palaearctic with a focus on diversity in the Mediterranean region and in the region around the Black Sea. Today, however, some species have been virtually kidnapped world.

Harmful effect

In counting to the slugs are many types synanthropic, ie adapted to the human species, which are often classified as pests .. De facto, however, there are only a few species that actually cause financially to determing damage ( can ), such as Reticulated the field slug ( Deroceras reticulatum ). Very problematic also abducted from their original habitat to other habitat types may be because there their natural enemies are often lacking.

System

The family is divided Agriolimacidae home village into two subfamilies, the subfamily Mesolimacinae is monotypic, containing only the genus Mesolimax with two types. The majority of genera with about 60 species currently set is placed in the subfamily Agriolimacinae.
