Well, this is a new type of Captcha I hadn't seen before. Problem is, in their attempt to defeat the bots, they also defeated me. I see two fish, an elephant, a horse, and two...blobby things? I'd guess one of the blobby things is the correct answer to the "created by humans" question, but darned if I know which. So I guess there's a 50% chance I'm not human. No surprise there.
