(1) The secret to the tape is that it emulates the hairs on the feet of a gecko .(2) In another example of blurry physical boundaries, consider the gecko , a lizard remarkable for its ability to walk upside down on ceilings.(3) Unlike these animals, geckos lack glands on the surface of their feet.(4) And how do geckos keep their feet clean, despite their adhesive traits?(5) If geckos were to rely solely on capillary adhesion for attachment, setal function could be constrained by relative humidity of the habitat.(6) While living here I have spotted many, including small shiny skinned skinks, geckos (jing-jocks and tokays), and large monitor lizards.(7) Police say burglars had broken in earlier that day, taking exotic animals and equipment worth Ôö¼├║640, including two bull snakes, a pair of hypo geckos , two skinks and a corn snake.(8) There are many other snakes of all different sizes, as well as chameleons, geckos , lizards, skinks, iguanas, spiders and huge tortoises.(9) It's quite a sight to see geckos , small tropical lizards, running up and down walls and across ceilings, without any trouble.(10) They're the tiny little ridges and hairs that geckos have on their feet.(11) Climbing geckos use all four feet similarly to produce positive fore-aft forces parallel to the surface that propel the gecko upwards.(12) In his suitcases were more than 200 live skinks, geckos , and frogs.(13) 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.(14) Since geckos have millions of these hairs on each foot, their combined adhesive force is hundreds of times greater than what is required for the gecko to hang from a ceiling by one foot.(15) 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.(16) The extraordinary adhesive capabilities of geckos have challenged explanation for millennia, since Aristotle first recorded his observations.
