Green Slug

Green Slug
Seattle, King County, Washington, USA
August 28, 2006
Size: approx 11cm
I'm placing this here, because I have been trying to identify this creature for some time, now. I am pretty sure it's Limax maximus, perhaps part albino, or an uncommon color variation. The thing that's getting me stumped is the transluscent quality and the color of the head/tentacles. I look at the regular Leopard Slugs and they too have a somewhat transluscent appearance in strong light, but I don't see the blue colorations (mentally visualizing the removal of browns).
Anyway, if anyone else has seen this color of slug, I would like to know about it. We have many, many varieties of different species up here in the Northwest and I would like to know if perhaps this is a newly introduced species or just a differently-colored form of a regularly encountered species.

It might be Deroceras reticulatum or related species. Introduced species.

Yellow Garden Slug - Limax flavus
I thought that it was Deroceras reticulatum, but someone in Flickr pointed me in the direction of L. flavus, because of the blue tentacles. It appears to be the one. Still an introduced species...There's also one called L. pseudoflavus, but I haven't looked into that one, yet.

This was confirmed as Limax flavus by Casey Richart who runs the Gastropods of Western Washington online key that I usually use to ID these things. I even mailed him a specimen and he says that it's a first "official" record for Washington State.
I think it's cool...

I've heard of "snail-mail"...
but this is the first example I've heard of involving actual gastropods...

I've never sent a live animal before...
I even have a photo of the specimen I sent him crawling into the container I mailed it in:
Here's a link to the set I created just for that species:

That thought had occurred to me...
I found a web site that I will go over today, plus I have the known ranges of various gastropods from the Evergreen University web site.
The first web site is
(It's not local, of course).
