Teeny tiny, itsy bitsy, teeney weeney chameleons!
The four new species belong to the genus Brookesia, also known as the leaf chameleons, which live in remote rainforests in northern Madagascar. The genus is already known to contain some very small species, with members typically resembling juvenile versions of larger species.
As small as these guys are, a super-tiny dwarf gecko found in the British Virgin Islands might be just a tad more wee.
