The Deep Sea Midwater | Worlds of the Deep, a collaboration with Schmidt Ocean Institute. Thank you to Brilliant for sponsoring Natural World Facts 🧠💡 - for a 30-day free trial and 20% off an annual premium subscription visit https://brilliant.org/NaturalWorldFacts/ In the deep ocean, life is divided between very different worlds inhabited by weird and wonderful deep sea creatures. In the midwater, 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 Midnight Zone and the Twilight Zone, where anglerfish, giant sharks, and bioluminescent wonders are found traversing the void. Join as we uncover fascinating deep ocean facts and mysteries. This film features only real footage of deep sea creatures. It is the combination of my Twilight Zone and Midnight Zone films, featuring re-recorded narration and updated visuals. You can find the episodes on my channel individually as well.

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!

The glass octopus is a deep-sea dweller that hides in plain sight. It is almost entirely see-through, feeding on marine snow. Footage provided by Schmidt Ocean Institute.

The dumbo octopus is the deepest living octopus in the ocean. It flaps a pair of enlarged ear-like mantle fins to move gracefully, steering with webbed arms as it traverses the deep sea void.

The chimaera, or ghost shark, is one of the oldest fish in the ocean. It's an ancient relative of true sharks that diverged from a common ancestor 200 million years ago. Sensitive electroreceptors on the snout and along the body allow it to detect prey in nearby water and the soft sediments at the bottom of the deep ocean.
