This little guy is called a Brookesia Chameleon and it measures (fully grown) at about an inch in length! They are one of the smallest reptiles on the planet. Not all chameleons can change color, but these little dudes can, making them insane to spot unless trained. When disturbed, they try to look as uninteresting as possible. There are 26 different types of these guys, and they are currently listed as threatened.
