Great Gray Garden Slug, Tiger slug, spotted leopard slug

Limax maximus is found commonly in West Coast gardens. It has spots on the mantle and spots or tiger stripes on the upper surface of its foot. It has a smooth, furrowless body with the pneumostome placement located near the rear edge of the mantle. It's length is about 4 inches (10 cm). It is four times faster than banana slug which is useful as it is predatory on other slugs. It originated from Asia Minor and Europe. (Gordon, 1994).

This slug is also reknown for it's ardent courtship. Great gray garden slugs mate while suspended from a slime cord (copulate midair). The courtship was captured photographically recently on my siding.
