About the gecko

Geckos are small lizards found in warm climates worldwide, and with more than 1,800 species they are one of the largest lizard groups. Most climb sheer walls and even glass on toe pads covered in millions of microscopic hairs that grip by molecular attraction, many have no eyelids and lick their eyes clean with their tongues, and unlike almost all other lizards, geckos call to each other with chirps and clicks. Most species are Least Concern, but island species are vulnerable to introduced predators.

Five things to know

  1. Geckos have specialized toe pads that let them walk on walls and ceilings, even glass.
  2. They are unique among lizards because many geckos vocalize with chirps, clicks, and sometimes loud calls.
  3. The leopard gecko has eyelids, which is very rare among geckos.
  4. Geckos can rapidly drop their tails to escape predators, regrowing them in weeks to months.
  5. Some geckos have no eyelids and clean their eyes with their tongues.
