Miscellaneous Interesting Facts

 Interesting facts about Chameleons?



1.     Almost half of the world’s chameleon species live on the island of Madagascar, with 59 different species existing nowhere outside of the island. There are approximately 160 species of chameleon. They range from Africa to southern Europe, and across south Asia to Sri Lanka. They have also been introduced into the United States in places such as Hawaii, California and Florida. 




2.      Chameleon eyes have a 360-degree arc of vision and can see two directions at once
Chameleons have the most distinctive eyes of any reptile. Their upper and lower eyelids are joined, with only a pinhole large enough for the pupil to see through. They can rotate and focus separately to observe two different objects simultaneously, which lets their eyes move independently from each other. This gives them a full 360-degree arc of vision around their body. When prey is located, both eyes can be focused in the same direction, giving sharp stereoscopic vision and depth perception. Chameleons have very good eyesight for reptiles, letting them see small insects from a long (5–10 m) distance. 




3.     Ballistic tongues that are 1.5-2 times the length of their body.

 Chameleons feed by ballistically projecting their long tongue from their mouth to capture prey located some distance away. While the chameleon’s tongue is typically thought to be 1.5 to 2 times the length of their body (their length excluding the tail), it has been recently discovered that smaller chameleons have proportionately larger tongue apparatuses than their larger counterparts. Tongue projection occurs at extremely high performance, reaching the prey in as little as 0.07 seconds, having been launched at accelerations exceeding 41 g. The chameleon tongue’s tip is a bulbous ball of muscle, and as it hits its prey it rapidly forms a small suction cup.
