Brazilian pygmy gecko (Coleodactylus amazonicus)

The Brazilian Pygmy Gecko, or sometimes 'unsinkable lizard', only grow to around 2 centimeters ​in length, which makes them one of the smallest reptiles in the world. Their smallness reaches to an extent that they are often eaten by insects, centipedes, and spiders! They live in areas where heavy rainfall is imminent, so to adapt, they have developed hydrophobic skin and are light enough to walk on water without sinking or developing the need to swim. 

They are only able to eat tiny invertebrates like fleas and mites.
