The Odd Things On The Smithsonian Site
The Smithsonian National Museum of Natural History has a great website displaying a large variety of the weird critters they've gathered over the years. Look at this and this strange creature.
If you click on "Detailed View" below any of the thumbnail pics here it will take you to another page the bottom of which is usually several other pictures of that particular specimen. There's a lot of other pictures that can be found by searching the rest of the site.
