We have long known that chameleons can quickly change their appearance in response to temperature or environment. Yet recently, scientists have identified an important factor in their ability to do this: chameleons “tune” the distances between nanoscale crystals in their skin that reflect light. As the distance between the crystals increases, the reflected colors shift from blue to green to yellow to orange to red as they progress from relaxed to agitated (or amorous). All chameleons have the ability to change colors, but some species (like the Panther Chameleon) can change color faster than most - in less than 20 seconds!
The panther chameleon is one of the most colorful of all chameleons. Madagascar is home to half of the world's 150 species of chameleons. A local proverb says: 'Manaova toy ny dian-tana jerena ny aloha, todihina ny afara,' which translates to: "Like the chameleon, one eye on the future, one eye on the past”. The future for chameleons in Madagascar is perilous. Deforestation and the pet trade have contributed to their declining population and many are threatened with extinction. Protection of Madagascar's chameleons and their habitat are critical.
