From a story in The Times of London, on Adam’s Bridge, or Ram Sethu, shoals between India and Sri Lanka, and religious and environmental objections against dredging there, a Hindu explanation on how palm squirrels got their stripes while said to be helping to build the bridge:
Tiny palm squirrels help by carrying pebbles to the waters edge and Rama, touched by their efforts, stroked one, marking it with the stripes — hence giving the five-striped palm squirrels their name
According to Kumaran Sathavisam, and to Wikipedia, however, the five-striped palm squirrel is a northern India species, not naturally occurring further south than central India.
