The chameleon changes its coloration depending on the situation
Popular culture often uses the nickname “chameleon” pejoratively to label people who have the ability to camouflage themselves, to blend in with the environment to go unnoticed at critical moments. This cultural trait has its roots in the phenomenon that different species of chameleons change their skin color depending on the situation. For example, the panther chameleon, one of the two hundred known species of chameleons, when young, changes its skin color, blending in with the environment, which helps it escape from its predators. This color change is due to the presence of nanocrystals in your skin cells that cause this effect when light falls on them. When two male panther chameleons confront each other, they change their coloration to a defiant yellowish red, just as when they are in the presence of a predator. On the other hand, to court a female (in the case of males), the panther chameleon, whose color is normally green or brown, dresses in his best pink clothes to impress her. In reality, this peculiarity of chameleons is a physiological reaction used as a form of communication. In addition to changing their coloration, chameleons can also change their appearance to appear larger in competitive situations. In normal situations, males are larger than females. As predators, chameleons have interesting machinery: a very long tongue, incredibly fast and extremely sticky to catch their prey, as well as eyes that protrude from their sockets, rotate 360 degrees and move independently. Almost 40% of the known chameleon species live in Madagascar and their natural predators are birds and snakes.Check out this YouTube video to witness the incredible color-changing ability of a chameleon!
