I got barraged with links to several giant isopod articles. That means two things: 1) you folks think of me (or my blog) when you see something ugly, and that's heart-warming (I think), and 2) there's consensus that the giant isopod has a permanent home here.
The giant isopod is the deep-sea cousin to the wood louse, or roly poly or pillbug, that you'll find in your backyard. This particular specimen is a good two and a half feet long, which is large or its kind, but not out of the ordinary.

But I didn't just get sent links. Sherry also sent me this post on how to make a plush giant isopod, from Deep Sea News.
