Great Grey Slug (Limax maximus)
This slug has many popular names, spotted leopard slug being one of them.
More information: http://en.wikipedia.org/wiki/Limax_maximus
It is the most commons slug in the toad’s garden, and it’s a blessing. It seems to be territorial, keeping other slugs, also invasive “killerslugs”, at a distance. Since the latter is spreading rapidly in Denmark, and have arrived to the neighborhood, next year the leopards must show value for my affection, please !
My friend Brian from Gourmethaven took a snapshot of the leopards attack on the “killerslug”, where you can see the fresh white wound. http://www.gourmethaven.dk/artikel/vis.php?id=204

That’s a really pretty slug! I used to live in northern California, and there we sometimes had ‘banana’ slugs. They were amazing — really big and, well, banana like.
I never knew there were good slugs and bad slug, and it’s too bad the leopard slug is losing it’s habitat to other invasive breeds.

I wonder if they are similar at all to the leopard slugs that are here in Aus’.
I only know of them here because of their mention in work done by Esther Deans about them and cannibal native snails.

I have a tent set up in the backyard for my kids. It rained a bit earlier, and I found one about 4″ long crawling across it. I’ve never seen a slug that big!!
