Chameleon, master of disguise

Chameleon, master of disguise (Picture 1)

1/24

The chameleon possesses unique skills, changing colors, moving eyes and sticking out tongues are the 3 unique skills it often performs. The chameleon has two barnacle-shaped eyes, and the left and right eyeballs rotate 360° respectively. When its left eye is aiming forward, its right eye is looking behind it, looking left and right, looking around, moving its eyes freely. The tongue of the chameleon is extremely long, and it is usually coiled in its mouth like a clockwork. When it finds its prey, it suddenly straightens its long tongue, shoots it out from the mouth, and preys with its tongue, such as digging into the sac. Chameleon’s best skill is to change color. The basic color of its skin is green, but it can change into dark green, light green, purple, blue, brown, etc. at any time, and it can even change into various "garish" pattern colors.

Chameleons are mainly distributed in Africa, and a few are distributed in Asia and southern Europe. The island of Madagascar in Africa is their paradise. There are about 160 species of chameleons, mainly distributed on the African continent and Madagascar. Among them, about half of them live in Madagascar. In Madagascar, the largest and most unique chameleon community in the world, 59 species are unique to Madagascar. . People are still discovering new species, or based on genetic analysis, the chameleon that has been mistakenly divided into subspecies is defined as an independent category.

The chameleon is very slow, and people use sloths to compare its careless appearance. Chameleons are reptiles that mainly inhabit trees and rarely visit the land except for laying eggs and courtship. Occasionally when they crawl on land, their claw tips touch the ground, and their front and rear feet are flattened and withdrawn outward. Obviously, the chameleon can effectively adapt to the gait crawling in trees and grass, and not only cannot hide itself on land, On the contrary, it attracts attention. Even when the chameleon flees in a panic, its speed does not exceed 6 meters per minute.

The chameleon is because it is good at changing the color of its body at any time with the changes of the environment. Discoloration is not only good for hiding oneself, but also good for catching prey. Discoloration is a physiological change that is accomplished by the expansion or contraction of pigment cells in the skin under the control of the autonomic nervous system. Another theory is that it has been discovered in recent studies that chameleons do not rely on pigment cells. Discoloration, but by adjusting the surface of the skin's nanocrystals, changing the color of light by changing the refraction of light. Discoloration can avoid natural enemies, express emotions, and resemble human language. Chameleon is a kind of "fickle" arboreal reptile. In nature, it deserves to be a "master of camouflage". In order to avoid the invasion of natural enemies and get close to its prey, this reptile often changes its body color inadvertently. Then he blended himself into the surrounding environment motionlessly.
