Geckos are small lizards famous for their ability to walk up walls and other sheer vertical surfaces, and to hang from ceilings. However, they come a cropper if they attempt to climb on non-stick surfaces! They're welcome creatures to have around in the house as they feast on the insects you don't generally want inside.
Scientific name: Gekkonidae
