Nano-chameleons are believed to be the world’s smallest reptiles.
Known as Brookesia nana, these tiny reptiles measure only 22-29 millimetres from tip to tail. They are so small they could fit on your nail.
That’s about the same size as a sunflower seed!
German scientists discovered two of the animals in Madagascar and published their findings in a journal called Scientific Reports in January.
They say it’s the smallest of 11,500 reptile species discovered on the planet so far.
Prior to this, the smallest known reptile in the world was Brookesia micra, a very similar species discovered in 2012.
