African pygmy mouse

Mice are easily recognized by their small size, but the African pygmy mouse takes that trait to the extreme. Measuring at under 7 centimeters in length and often weighing less than 10 grams, it is the world's smallest mouse.

In fact, it is so small that it typically hydrates itself solely by licking dew off tiny pebbles that it cleverly stacks in front of its burrow.
