Here's a green anole. He's not really doing anything particularly cute, but LOOK AT THAT FACE!!!!

I can tell he's a he because of the flap of skin under his throat. That's his dewlap, and he can extend it to a large, bright red semicircle. This is the sort of thing that impresses the ladies if you're an anole - that and showing off your pushup routine. Anoles are great at doing pushups; they will often do a demonstration.

Also, they're crazy smart, and they handily outperform rodents and songbirds on several animal cognition tests. They can learn new tricks by watching other animals do them, learn to manipulate objects using their snouts or mouths, and are *extremely* adaptable. It turns out that even if your brain is the size of a peppercorn, living in tree canopies and competing for your main food source with birds that can kill you, you'll end up with an extremely well-optimized peppercorn.
