Lowlands Plain-backed Ctenotus (Ctenotus essingtonii essingtonii)
These little striped skinks often showed up in the same areas as the littler still Carlia amax, but were much less numerous, and even twitchier, so I got a lot fewer and lower-quality photos.

I’ve written up an account of this three-week trip to Australia here.

The only place I saw more than one of these skinks was near the parking lot of Litchfield National Park’s Wangi Falls. One of them even paused in the open for more than five seconds.

Lowlands Plain-backed Ctenotus (Ctenotus essingtonii essingtonii)
There are so many species of skinks in Australia that I assumed I had probably photographed several different small striped species. But when I reviewed my photos back in the U.S.A., I decided that they were all C. essingtonii.
