“Rainbow Squirrel’: The largest squirrel in the world lives in India. It grows up to a meter long and weighs up to two kilograms.

Scientists still don't agree on why the squirrels are so colorful. One theory is that their colorful fur coats could be used for camouflage in the forests. The bigleaf forests where the squirrel lives create a mosaic-like pattern of sunspots and shadows during the day that resembles the animals' fur markings. The rodents support their nests using forks of branches that they intertwine with climbing plants.
