Tiny primate rediscovered 80 years after it was thought to be extinct

On a misty mountaintop on the Indonesian island of Sulawesi, scientists have observed one of the planet's smallest and rarest primates - 80 years after it was thought to have become extinct.

The pygmy tarsier is a mouse-sized big-eyed animal that weighs almost 60 grams. The last one spotted alive was in 1921 before the species went into hiding.

Their descendants certainly didn't seem thrilled to be found.
