Wind down by escaping into nature. Part soundscape and part bedtime story, The Sleeping World is an intimate journey through ecologies around the world.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

This is the world in its natural state, defined by seasons, routines, and cycles. By the time these platypuses are curled up in their burrows and ready to rest, you’ll be ready to rest too.
