  • Geckos quite literally have sticky fingers that allow them to stick to any surface as long as it’s not Teflon.
  • Even though geckos’ sticky fingers look like the work of glue, the geckos stick due to microscopic hairs.
  • Geckos’ eyes are super sensitive to light. In fact, they are 350 times more sensitive than human eyes.
  • Geckos have the ability to distinguish between different colors even when there is so little light that humans are essentially colorblind.
  • Even though geckos have great eyesight, most do not have eyelids. Instead, they use their tongues to clean off their eyes.
  • Geckos have the ability to vocalize, such as by making clicks, barks, and chirps, although the creatures tend to be very quiet.
  • Not all geckos have legs. There are some species that have no legs and almost look like snakes. However, they are different from snakes in that they can vocalize, hear wonderfully, and can detect different tones that snakes cannot.
  • Certain species of geckos have flaps of skin around their feet and tails so that they can glide through the air.
  • The smallest gecko is not even two centimeters long. It is native to the Dominican Republic and Beata Island.
  • The two smallest types of geckos are the smallest types of lizards, too.
  • Scientists can easily determine if a gecko is diurnal or nocturnal by looking at the gecko’s pupils. Nocturnal geckos have vertical pupils, whereas diurnal geckos have round pupils.

  • Geckos shed their skin very frequently. Some species shed their skin as frequently as every two weeks.
  • Geckos can replace all 100 teeth in a period of three to four months.

  • Geckos are hardy reptiles because they can live to be 20 years old. Some geckos have even lived to be nearly 30.
  • Geckos often protect their territory from one another through their unique vocalizations.
  • Gecko species are able to drop their tails to distract predators, and many can even grow these tails back. However, some geckos will be able to drop their tail but not grow it again.
  • You can easily spot where the gecko will drop its tail by looking for a score of spotted lines. This spotted line is where the tail will break off from the body.
  • If a gecko survives after shedding its tail, it will often go back to see if it remains. If it is still there, it will eat its tail for nutrients because of the next fact.
  • Whenever times are robust in terms of food, geckos store extra fat and nutrients in their tails that they can use during the tough times.
  • Many geckos can change their colors to match their surroundings, much like a chameleon. They can even do this without seeing their surroundings.
  • The satanic leaf gecko has such a unique tail that it looks like a dead leaf.
  • Whenever a gecko is falling, it twists its tail into a right angle so that the animal lands on its feet. It only takes 100 milliseconds for geckos to direct their tail in such a way.
  • Geckos primarily only eat bugs, which classifies them as insectivores.
  • Even though geckos are considered insectivores, they are known to eat other creatures if they’re small enough to do so.
