Chameleons are certainly among the most photogenic reptiles — and not just because they've mastered the "bored model" look. With somewhere around 160 species, these eccentric lizards come in a range of shapes, sizes and, of course, colors. Chameleons can thrive anywhere from the desert to the rain forest, and many of them are endemic to Madagascar. Browse through of some of the weirdest-looking species across the globe.

One of the strangest of all is Jackson's three-horned chameleon, pictured above, which ranges throughout East Africa.

Contrary to popular belief, chameleons don't change their colors to blend into their surroundings. They've adapted to their environments so that their natural coloration helps to camouflage them. They change color according to their mood, like the defensive Namaqua chameleon putting on his threat display — it is normally a light beige color to match the sand, but it turns darker to show off its bright mouth when attempting to scare off intruders.

The brown leaf chameleon lives on the forest floor of Madagascar — which explains its technique of playing dead: it folds up its limbs and rolls over to its side, looking just like a dead leaf.
