Sanctuaries in the Dark, a relaxing Deep Sea documentary. Thank you to Opera for sponsoring Natural World Facts - download Opera for free at https://opr.as/Opera-browser-NaturalWorldFacts Sink into this relaxing deep sea documentary, a calm descent (structured for deep sleep or relaxation) through some of the most iconic species and features of the twilight zone (mesopelagic), midnight zone (bathypelagic), abyssal plain, and hadal trenches. Designed for sleep, study, focus, meditation, and ASMR, this film blends ocean ambience, gentle narration, and fascinating scientific knowledge to give a “space documentary” feeling (but underwater and therefore far superior, wink wink). Meet real deep sea creatures: sixgill sharks, ghost sharks (chimaeras), bigfin squid (Magnapinna), telescope octopus, siphonophores (Bathyphysa), drifting jellyfish, and the quiet clean-up crew of the abyss... sea cucumbers and giant isopods. Visit hydrothermal vents, where chemosynthetic microbes power oases of life with giant tubeworms (Riftia pachyptila) and Pompeii worms; glide over seamount coral gardens and ancient sponge grounds; witness wood falls and whale falls turning darkness into cities of life; and pause at octopus nurseries warmed by gentle seepage. If you love interesting science videos, relaxing nature films, ocean sounds, or space vibes for sleep, this is for you; a calm, immersive journey where light is a language and the sea feels as vast as the cosmos. This film features only real footage of deep sea creatures, filmed by the incredible ocean exploration institutes of NOAA and Schmidt Ocean Institute.

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.

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.
