Leaf-tailed Gecko — Softening the Outline

Mottled skin and a fringe around the body help a gecko merge with its resting surface.

TRY THIS

Look along the lower jaw and belly for the fringed edge. Notice how different that edge is from the clear outlines of the toes and eyes.

The story behind it

Giant leaf-tailed geckos are nocturnal forest lizards from Madagascar. They rest by day on branches, trunks and other forest surfaces, where their appearance can conceal them.

What’s happening?

Colour matching alone would leave a recognisable silhouette. Fringed skin along the jaw and body can flatten against a surface and soften the boundary between animal and background. The broad tail adds a leaf-like shape. Several features work together to hide the outline.

ABOUT THIS PHOTOGRAPH

This photograph’s dark background reveals the body fringe clearly; it does not show the gecko concealed against a matching trunk.
