not exactly a geoduck, but...

The gastropod life in Washington State is awesome. I think I have seen about 5 different type of slugs while I've been here. After some research, I found out that there are Spotted leopard slugs on my backyard. I want to see them mating just out of curiosity:

After this, the slugs will climb into a tree or other high area and then, entwined together, lower themselves on a thick string of mucus and exchange sperm.

Even more interesting, are the Red Slugs. I suppose that their defense mechanism is camouflage. They look just like duck shit. Now that's something I don't want to step on!
