Geckos are common worldwide in warm climates, and have large heads and short, stout bodies.
Many have no eyelids. Their sticky toe pads enable them to climb vertically and walk upside down on smooth surfaces in their search for flies, spiders, and other prey. There are about 850 known species of gecko. A new species of gecko Tarentola mindiae was identified in Egypt's Western Desert in 1997. The name comes from the clicking sound made by the lizard.
