Explore the Unknown: Top 8 Jaw-Dropping Fun Facts About the Twilight Zone Ocean

1. Party in the Twilight Zone

In the depths of the ocean, where the sun barely shines and the nightlife really glows, there exists a perpetual happy hour for fish and squids alike: The twilight zone ocean, or mesopelagic zone, is home to over 90% bioluminescent metazoan species, relying on their living light for communication, camouflage, and prey attraction. Adaptations like heightened visual acuity make it possible for these creatures to navigate and hunt, resulting in an underwater hotspot with an estimated biomass of at least 1000 million tonnes – talk about a lively ecosystem!

Hold onto your umbrellas, folks, because it's raining marine snow in the twilight zone of the ocean! But this isn't just any old precipitation: marine snow actually helps regulate Earth's climate by absorbing huge amounts of carbon dioxide, keeping it out of the atmosphere for centuries, and has even contributed to cooling down our planet over the last 50 million years. Talk about a flaky hero!
