Knowra Gecko Gecko Geckos are a diverse group of lizards found on every continent except Antarctica. Many species climb smooth surfaces using microscopic structures on their toe pads.
Setae : Microscopic hairlike structures that cover the toe pads of many geckos and generate dry adhesion. Setae create the contact with surfaces that lets many geckos climb.
Squamata : The reptile order containing lizards, snakes, and amphisbaenians. Geckos are one lineage within this large group of reptiles.
Gecko-inspired adhesive : An engineered adhesive that imitates the dry, reversible attachment of gecko toe pads. Gecko toe structures have inspired reusable adhesives that leave little residue.
Tokay gecko : A large Southeast Asian gecko known for its blue-gray body, orange spots, and loud calls. Its size and vocal behavior contrast with the small, quiet geckos familiar in homes.
Anole : A diverse lizard group, especially abundant in the Americas, whose species often have adhesive toe pads. Anoles also climb with adhesive pads, but their evolutionary history differs from geckos'.
Van der Waals force : A weak attraction between atoms or molecules arising from fluctuating or permanent electric dipoles. The combined attraction between setae and a surface helps explain gecko toe adhesion.
Lizard : A reptile belonging to one of the many lineages traditionally grouped as lizards. Geckos are lizards, but their distinctive traits set them apart from many other lineages.
Biomimetics : The design of materials, devices, or processes inspired by biological systems. Geckos are a prominent model for translating biological attachment into engineering.
Satanic leaf-tailed gecko : A Madagascan gecko whose flattened body and tail resemble dead leaves. Its camouflage shows how some geckos evade predators without relying on speed.
Skink : A large lizard family often recognized by smooth scales and elongated bodies. Skinks illustrate a successful lizard lineage that generally lacks gecko-style adhesive toe pads.
