Despite the fact that I went to a great public school, I guess we just didn't have the funding to do balloon animal dissections in our bio classes. If only I'd known about the delicate and beautiful bone structure and vein patterns of balloon animals, I might have been less inclined to pop so many of them over the years. In any case, I've changed my ways since seeing Jason Freeny's diagram, and I'm assuming you can too. Don't let it scare you. Let it free you. Link via Ohgizmo.
