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

At the southernmost tip of South Africa, where fresh and salt water collide, a tiny seahorse appears to levitate. Seahorses are the ocean’s slowest swimmers, but they have one of the world’s fastest muscle contractions, using it to suction up their prey. In this episode, we meander through eelgrass with a male Knysna seahorse as he twines tails with his partner, changes color to match the sand, and even gives birth to a brood of tiny seahorses.

This is the world in its natural state, defined by seasons, routines, and cycles. By the time this seahorse is ready to drift off, swaying gently with the current, you’ll be ready to drift off too.
