Madagascar has more than its fair share of endemics, but some are easier to spot than others. This image shows a mossy leaftailed gecko on a tree, but the point at which one stops and the other starts is far from obvious. It’s not just the lizard’s uncanny, bark-like colours and textures – a lacy flange around its body, legs and chin provides the finishing touch to a seamless transition. Geckos are thought to be able change colour to blend into their background, like chameleons. But perhaps the tree is mimicking the lizard.
