Why the Ocean Has a Twilight Zone | Unveiled

What is the Twilight Zone of the Ocean? Is it possible that the Earth has a hidden place, just hidden from sight, filled with wonderful and inconspicuous views? Filled with strange, luminous animals that even our wildest fantasies could not come up with, creating an ecosystem so elusive and unique that it could be alien? Yes, that is right. This is revealed, and today we answer an extraordinary question; What is the twilight zone of the Ocean? Are you a monster for facts? Are you constantly curious? Then why not subscribe to Unveiled for more clips like this? And ring the bell for more exciting content! Discovered between 650 and 3,000 feet below the surface of the water, the twilight zone of the ocean — also called the “mesopelagic” or “middle pelagic zone” – extends from the point where sunlight begins to fade, to a depth where all light ceases. You can dive deep enough to enter it, but people almost do not explore it – mainly because it is unattainable for non-specialist diving expeditions, but not deep enough to be the main target for expensive Submarines, which we send to the sea bottom. So, the twilight zone is an abandoned middle space, but now there is a big impetus for further research. From the point of view of the animals that live there, this is an area of ​​the sea, filled with mysterious, often luminous creatures. Small fish, such as a hatchet and lantern fish, use luminous internal organs – or photophores – as a form of camouflage, called “counter-lighting”. This disguises them to look like scattered photons of sunlight still making their way through the water, reducing their silhouette and protecting them from predators. However, other creatures use their glow for a variety of reasons — including a nightmarish fishing fish (luminous bait is used as bait) or an ominous sounding vampire squid (which injects luminous liquid as a protective mechanism). And there are still many deep-sea dwellers who use their glow to attract comrades — like birds and their feathers. And, importantly, the twilight zone is also home to tiny bristles – fish, which is actually the most numerous vertebrae on the planet, with a population reaching thousands of trillions. This may be largely unexplored, but it is clearly a massive environment and an integral part of marine ecology. Only recently have we discovered that large marine predators, such as whales and sharks, regularly dive down into the twilight zone when they feed. There is a huge krill population where krill sits right at the bottom of the food chain. Thus, the twilight zone is an important base for all marine life and, therefore, all life on Earth. Similarly, this untapped ocean world can have a significant impact on our climate. Given the huge number of animals that inhabit it, the twilight zone also undergoes a huge daily mass migration — thousands of creatures “visit” the surface and essentially remove carbon from the atmosphere. Take, for example, salpies, which are strange, sticky-bubble-like creatures you may have already seen on the beaches. They are called “ocean vacuum cleaners” because they feed on algae (which feed on carbon) before they digest and process them deeper into the sea. Although we do not really know what happens to this carbon in the future, the turd is considered one of the many ways that the mother can cleanse the environment. But the problem with analyzing the twilight zone of the ocean is that much of what we know is still based on assumptions. This zone was only opened in the 1930s by the US Navy, which reportedly took it for the ocean floor because it is so densely populated by billions of tiny fish. Standard sonar technologies are not capable of mapping individual species, but some estimates state that there may be more fish biomass in the twilight zone than in the rest of the ocean combined. It is a mysterious world waiting to be explored, but it is also under increasing threat. As trawlers and fishing vessels hunt deeper and deeper in search of what they need (including krill for krill production), we could see that the twilight zone had diminished before we began to properly study it. According to biologist Heidi Sosik, we are on the verge of a “gold rush in the twilight zone,” which has dramatic and disastrous consequences for the ocean as a whole. The combination of over-fishing with increased pollution of the sea, which induces the migration of whole species, and whole ecosystems are under the pressure of adaptation or death. An unexplored sphere, almost completely alien to science, but one that could well contain the secrets of understanding the wider world of nature and all life on Earth – if
