Anole Annals

All of us that observe and study Anolis (and Sitana) know that dewlaps make our favourite lizards special. Dewlaps can be key for species identification, and we pay a lot of attention to variation in their size and colour. But what exactly constitutes a dewlap?

I’m currently compiling a list of all lizard species with dewlaps, and have run into the problem of how to define a dewlap. Our trusted friend Wikipedia defines a dewlap thus:  a longitudinal flap of skin that hangs beneath the lower jaw or neck of many vertebrates. Helpful, perhaps, but only slightly, as the difference between a small dewlap and a puffed-out throat is not always obvious.

So we’re turning to you, dear reader, to help us figure out what a dewlap is. I think the easiest way to do so is by showing you a number of pictures of lizards and asking you to deliver a verdict on whether these lizards are in fact dewlapped (photos from various internet sources). Feel free to offer an alternative definition also, if you’d like.

I’m currently preparing a grant proposal featuring Anolis sagrei for a philanthropic foundation with broad goals that extend well beyond biology. The people reading this proposal will thus have diverse backgrounds, probably mostly non-biological and certainly non-herpetological. In reading a draft of the proposal, a friend remarked “This lizard needs a new name for this grant!” And, indeed, on reflection perhaps “brown anole” is not the most exciting name for the general public.

So, who wants to help re-brand A. sagrei? Of course, an obvious possibility is Sagra’s Anole, since the species was, after all, named after Mssr. Ramon de la Sagra*. But…that’s not really that exciting either. My friend (a biologist) suggested “the tramp anole,” using “tramp” in the ecological sense of a weedy species that is able to colonize and establish in a wide variety of habitats. A possibility, for sure, but maybe some of the other connotations aren’t so good. His second suggestion, though,  merit’s consideration. Turns out that “sagre” in Italian means “a festival.” And what lizard could be more of a partier than the ever-flashing, always rollicking, A. sagrei? So, I put it to you, anole world, what if we start referring to this species as “the festive anole”?

*It’s an interesting story how the species ended up A. sagrei, and not A. sagrai, but that’s a tale for another time.
