Even though anoles aren’t the only lizards to have evolved dewlaps, their spectacular diversity of dewlap shapes and sizes certainly makes them leaders in the global arms race for dewlap dominance. Nevertheless, I recently came across some photos of the spectacularly dewlapped-agamid Sitana ponticeriana doing something I don’t think anoles are capable of – displaying while standing on two hind limbs. I’ve seen Australian agamids stand up for extended periods of time to display, dissipate heat, or scan the horizon, but I’ve never seen an anole do this for more than a few seconds while reaching for a new perch. Sure, anoles can do lots of other stuff to get the message across – push-ups, full-ups, elaborate tail-wags, tongue protrusions, nuchal crest extensions, gapping, etc. – but I’m just not sure they’re built to stand. My question to all the anoles lovers out there: has anybody ever seen one of our beloved creatures displaying while standing on its hind-limbs?
PS – Lots of other amazing photos of the dewlapped agamids are on Flickr
