Interested in more about geckos?

My research investigates why animals are shaped the way that they are shaped. I focus on gecko lizards, and their sticky toe pads. There is much variation in toe pad shape and size across species, suggesting that geckos are likely adapted to particular environments, yet no one has investigated how species use different habitats. I plan to measure the texture of surfaces used by geckos in Madagascar to see which kinds of toe pads are adapted to which environments.
