Over the last 100 years of observing researchersoceans sometimes managed to detect at great depths not only fish, but also octopuses. It was believed that cephalopods can sink to a depth of 3,000 meters, but in 1971 an octopus was photographed in the vicinity of the island of Barbados, which lived at a depth of 5145 meters! Then it seemed like something incredible, and since then, scientists have not been able to capture these invertebrates even lower. They concluded that octopuses cannot climb to a depth below 6,000 meters on their own. However, the new discovery of the Five Depths expedition called into question this statement: the researchers were able to photograph the octopus at a depth of almost 7000 meters!
The deepest octopus
The find was made during the expedition, whichwas held in 2019. It was dedicated to exploring the deepest places of the five oceans. During a dive in the Sunda Trench of the Indian Ocean, the maximum depth of which exceeds 7,000 meters, unusual cephalopods were discovered. Yes, the octopus would not be alone - these were two individuals that hit the camera lens twice. Discovered invertebrates belong to the genus Grimpoteuthis; they are also called "Dumbo octopuses", the fins on the sides of their mantle resemble the ears of an elephant from the same cartoon. Moreover, if the first octopus fell into the lens at a depth of almost 5,800 meters, which is also a lot, the second climbed much deeper - at 6,957 meters.
Despite the fact that octopuses of this speciesreferred to as deep-sea, before scientists could not even think that these creatures could swim so deeply. The length of the first octopus found was 43 centimeters, and the second - 35 centimeters, that is, a smaller one swam to a greater depth. Shellfish almost did not pay attention to either the camera or the bait, which the researchers placed.
This discovery greatly puzzled scientists, becausenew observations expand the range of octopuses by as much as 2,000 meters in depth. Researchers may have encountered an unusual population of these invertebrates, and this is a “one-time action,” but there is every reason to believe that octopuses are found at such depths around the world. And maybe even deeper. In this case, octopuses can have access to almost 99% of the entire seabed.
The deepest creatures
In the future, scientists intend to continue the studythe deepest places of the oceans of the world to find other amazing organisms. The greatest interest, of course, is the Mariana Trench - this is the deepest part of the world's oceans for many years excites the minds of researchers. There was a time when strange sounds began to be heard from the bottom of the basin, which were recorded from the surface of the ocean. Scientists and readers in our Telegram chat have suggested that this may be a monster and a species unknown to science. Ufologists, however, suggested that this was an alien submarine ship. As a result, it turned out that baleen whales can make such sounds. At the same time, there is one inconsistency in theory: usually, whales reproduce such sounds only in winter during the mating period, and signals are recorded throughout the year. So, perhaps, the Mariana Trench will nevertheless present a couple more surprises in the future.
Many researchers in recent years have tried“Domesticate” octopuses and start growing them on farms, like fish, crabs and other inhabitants of the seas and oceans. In many countries of the world, experiments are being carried out on genetic modifications of cephalopods, but this can lead to certain environmental consequences.
Creature full octopus farm entail environmental pollution with nitrogen and phosphorus, which can cause a massive spread of diseases not only among the inhabitants of marine flora and fauna, but also its terrestrial representatives.
The fact is that octopuses are different from othersliving creatures of our planet with their unique intelligence and skills to solve complex problems. They are not only able to distinguish between people, but even fall into anxiety and depression, which can not be said about most aquatic inhabitants. Therefore, catching an octopus is not so simple. You can think about it the next time you order an octopus in a restaurant somewhere in a beach resort, because these mollusks are a delicacy in many countries of the world.
