The non-chemosynthetic regions of the deep are divided into two very different worlds. First is the midwater, where pelagic wanderers tread migratory routes that span entire oceans, and planktonic drifters and their predators take part in bioluminescent light shows. It is separated into zones based on depth, including the sunlight zone (epipelagic), twilight zone (mesopelagic), midnight zone (bathypelagic), abyssal and hadal zones. And below, lies the deep sea floor. A kingdom of mud and ooze, where sessile creatures cling to any solid outcrop and corals craft kingdoms on the seamount crusts. The worlds of the deep sea could not be more different, and yet their stories are fundamentally intertwined. In this episode, we delve into the Twilight Zone.

This channel (Natural World Facts) is a solo passion project dedicated to exploring the wonders of the natural world and telling stories that inspire! I'm so excited to share this series with you at last. Schmidt Ocean Institute (SOI) is a non-profit oceanographic research foundation that has been pioneering deep-sea research and discovery since 2009, on board their old vessel RV Falkor and their new RV Falkor (too). Their remotely operated vehicle (ROV) SuBastian is equipped with a suite of sensors and a 4K camera that has illuminated the depths and live-streamed dives around the world. Most footage shown is filmed and provided by SOI. Huge thank you to them for contributing their footage, and working with me to create this series!
