Limax Maximus

Limax maximus (literally, "great slug"), also known by common names such as the great grey slug, or the leopard slug, is one of the largest kinds of keeled air-breathing land slug in the world, (Limax cinereoniger being the largest). It is in the family Limacidae, the keeled slugs.

Limax maximus is the type species of the genus Limax. The adult slug measures 10-20 cm (4-8 in) in length and is generally a light greyish or grey-brown with darker spots and blotches, although the coloration and exact patterning of the body of this slug species is quite variable.

This species has a very unusual and distinctive mating method, where the pair of slugs use a thick thread of mucus to hang suspended in the air from a tree branch or other structure.

Although native to Europe, this species has been accidentally introduced to many other parts of the world.
