Researchers have newly revealed four new chameleon species, which level between the world’s tiniest reptiles. Adults of the smallest species are just over an inch from snout to tail. A species of chameleon small sufficient to simply perch on a match head has been discovered on a tiny island off Madagascar, a group of scientists has announced. The four new species belong to the genus Brookesia, also known as the leaf chameleons, which are already known to contain some very small species, with members typically resembling younger versions of larger species. Mature males of the B. micra species grow to only now over a half-inch (16 millimeters) from nose to bottom, making them some of the smallest reptiles on Earth.
