Forget changing color—the newest chameleons known to mankind are hard to find for a whole different reason. They're miniature!
Four new species, informally known as leaf chameleons, were discovered in a remote Madagascar rain forest. They're roughly the size of a fingernail—an inch long from snout to tail. The little creatures don't get the title of smallest reptile—the dwarf-gecko found in the British Virgin Islands is tinier—but they're pretty close.
Why so small? Scientists believe this island dwarfism may be due to limited resources and a need to procreate faster. Their survival is also currently threatened by deforestation.
