    • Perhaps 100 million years ago, the ancestors of today's geckos became nocturnal predators.
    • Experiments using X-ray bombardment eliminated electrostatic attraction as a necessary mechanism for setal adhesion since the geckos were still able to adhere in ionized air.
    • A wide variety of birds, lizards and marsupials are depicted, including kangaroos, wallabies, goannas, leaf-tail geckoes and many other animals from the region.
    • Unlike these animals, geckos lack glands on the surface of their feet.
    • On the poorly appreciated role of reptiles and amphibians, he said that geckos, garden lizards, frogs and toads have a vital role to play in the ecosystem.

    • They're the tiny little ridges and hairs that geckos have on their feet.
    • If geckos were to rely solely on capillary adhesion for attachment, setal function could be constrained by relative humidity of the habitat.
    • There are many other snakes of all different sizes, as well as chameleons, geckos, lizards, skinks, iguanas, spiders and huge tortoises.
    • But the design of geckos ' feet, with their huge number of spatulate tips on every sera of every toe, allows many atoms to become intimate with a wall and act as a sort of glue.
