Drain the Oceans season 4 episode 10, Sea of Secrets, takes viewers on a deep dive into the mysteries that lie beneath the surface of the Indian Ocean. As one of the least explored bodies of water in the world, the Indian Ocean is home to some of the most fascinating and enigmatic creatures on the planet, from the elusive giant squid to the beautiful but deadly box jellyfish.

Throughout the episode, viewers will travel to some of the most remote and inhospitable regions of the Indian Ocean, where cutting-edge technology and innovative research techniques are being used to unlock the secrets of the deep. From the frigid depths of the Southern Ocean to the warm tropical waters of the Maldives and beyond, this episode is a fascinating journey through one of the world's most mysterious and little-understood bodies of water.
