Slug, Snail


This snail has gradually been given many names. It goes by names such as Iberian Slug, Spanish Slug, Snail Killer and Latin names Arion lusitanicus and Arion vulgaris. Nicknamed killer slug has probably been partly due to its large appetite for garden plants, and partly because it can act cannibalistic. The snails will usually only eat conspecifics if they are debilitated or dead.


Killer Auger, like other species of slugs no house, and is therefore in many contexts referred to as a slug. This is taxonomically incorrect, since the order of nudibranchs (Nudibranchia) only marine snails.

Killer Auger show great variation in color from orange to dark brown - almost black, most typically is brown red shades. It also found white and partly white copies (albino and partial albino). The large color variation makes the killer snails can easily be confused with either red slug (Arion rufus) or brown forms of the native black slug (Arion ater). Red slug described often as more bright red confusion opportunities).

Very young individuals of the slug are often bright with dark bands down the side and a small orange box on top of these. These dark bands are also in very young individuals of both red and black slug, but in these species disappear early, as they are covered by other pigment.

The fully grown, mature killer snails are about 7-15 cm long. Once again there is a large overlap with the closely related red and black slugs, as they respectively when the sizes of 10-20 cm and 8-18 cm. When the eggs hatched snails are kids around 1 cm in size. Looking at an area will often find snails in different ages, and thus snails of all sizes.

Other features that can be highlighted is that bottom typically orange brown with distinct dark transverse striping, so it looks as if the sole is sewn to the body by throwing things. Both the black and red slug does have this cross-striping, but less obvious, and in red slugs is less regular.

Eggs of killer snails are usually round or oval (approximately 4 mm in diameter). The eggs hatch milky white or with an orange surface - older eggs are often yellowish.

Protection and control:

Status of control:

The species is widespread and a major problem for many.
