While I was photographing some birds, I looked over and saw this lava lizard peeking at me from behind a rock. There are many different species of lava lizard on the Galápagos Islands, all however, are believed to have evolved from a single ancestral species. The different species are colored a bit differently depending upon the island that they inhabit — in other words, on islands with more black lava rock, the lizards are darker, whereas on light sandy islands, they are much lighter in color.
