Top 15 amazing secrets and mysteries of the world’s oceans (15 photos)
If you think that humanity has already studied everything on this planet, then you are deeply mistaken. The ocean is one of those natural phenomena that seem familiar at first glance, but in fact conceal many unsolved mysteries. Everyone has probably heard about the sunken Atlantis and the Bermuda Triangle. However, this is not all the mysteries and wonders of the ocean, which still amaze scientists. Here are 15 of the most incredible facts about the ocean and its inhabitants.
1) Luminescent plankton From the outside it seems that you got to another planet – the blue glow coming from the water, no association with the planet Earth. In fact, this amazing glow is caused by luminescent plankton. And although it looks fabulous, luminescent plankton is not the only creature on earth that has this ability – fireflies do the same thing, only on land.
2) Red tides Sounds both beautiful and creepy at the same time. And such tides do pose a danger. A special kind of algae bloom makes the water red. The degree of danger depends on the concentration of these algae: during blooming, they release a special toxin, which can destroy fish, plants and other living organisms, thus upsetting the balance of the ecosystem. For humans, this toxin can also be dangerous because, depending on the amount of it in the water, it can cause itching and more serious allergies. There have been known cases where there have been so many of these algae that the toxin has even permeated the air.
3) Cannibalistic sharks No, we are not talking about the fact that a shark can eat a human – we have known that for a long time. What is much more surprising is that a shark can attack its own kind – small sharks, sometimes even of the same species. Scientists have only recently come across this behavior of sharks. It is believed that they are only capable of this if they are hungry and hungry for a long time.
4) Artist Fish On the bottom of the ocean, patterns similar to the ones we draw with a stick in the sand have been discovered. It turns out that these circles are “drawn” by male Fuga fish to attract females.
5) Pyrosomes Pyrosomes are fascinating underwater creatures. They look like huge, hollow, tubes closed at one end with fluorescent elements. They can reach several meters in length. In addition to their alien appearance, they are also amazing because this tube, thought to be a single creature, actually consists of many small organisms which copy themselves to form a huge colony, from the outside appearing to be a single organism.
6) Glass squid
This type of squid has a special organ that makes its body completely transparent. And not all glass squids live in great depths. There are subspecies that live in well-lit shallow water, so the transparency perfectly helps them to hide from predators.
7) Underwater Waterfalls You may recall the one on the island of Mauritius, but the largest underwater waterfall is in the Danish Straits. These amazing natural “tautologies” are formed where two currents, warm and cold, meet. Since the cold water is heavier than the warm water, it literally falls down. So much for the waterfall. The only pity is that the vast majority of these phenomena are hidden from the human eye.
Mysterious disappearances There are a lot of stories about disappearing ships and planes: some just disappeared from the radar, others had time to inform the dispatchers about the malfunctions. What these cases have in common is that the ships and planes were never found.
This time we are talking about the American submarine. In 1968 it disappeared without a trace in the Atlantic Ocean. There were many rumors surrounding her disappearance, including a torpedo that exploded and Soviet secret service machinations.
9) A mysterious structure at the bottom of the Baltic Sea Although we talk about the oceans in this article, it is impossible to avoid this mystery. In 2012, a structure was found at the bottom of the Baltic Sea, generating a new round of rumors about regular UFO visits. Not without reason, we must say. The structure is reminiscent of the famous ship from the “Star Wars” universe, the Millennium Falcon. Scientists are still unable to say exactly what this phenomenon is. The natural origin is extremely doubtful, because the construction includes metal elements, which could not have formed naturally. One version is also the assumption that the structure was built during the ice age.
10) Black holes Everyone knows what black holes are in space – invisible to the human eye, they create a vacuum into which all objects in the vicinity are drawn. Some time ago, scientists discovered about the same thing, only under water. This powerful vortex pulls in everything in its path.
11) Ice Flowers Fragile, crystal-like flowers can be found all over the Arctic, as well as on ice drifting in the ocean. In addition to being fabulously beautiful, they are also a source of sea salts and other elements that eventually, evaporate and remain in the atmosphere.
12) Underwater icicles They are found in cold seas and oceans, especially near glaciers. When seawater freezes, some of the salts are displaced, forming a saturated and heavy salt solution that runs down the ice into the normal, less cold and salty seawater. This solution then sinks down by its own gravity, freezing the water with which it is in contact.
13) Killer Waves Killer waves are extremely rare. And thank goodness. Their height reaches 30 meters, and it is almost impossible to predict their appearance. Sailors say that such waves look like real walls of water.
14) Underwater structures Near one of the Bahamas islands, called Bimini, scientists discovered something that resembles an ancient road. That would be OK, but the road was underwater! Of course, the discovery was a sensation, and immediately generated a lot of rumors about the discovery of the lost Atlantis. However, in the course of further research, there is reason to believe that this road is the result of geological changes, rather than human activity.
It should be noted that the Bimini Road is not the only underwater attraction claiming to be Atlantis. Off the coast of Japan there is an amazing place called Yonaguni. The Japanese believe that these are the remains of an ancient civilization that most likely died as a result of the tsunami.
15) The Ocean Milky Way Blue flashes have recently been observed wandering in the ocean. They are amazing because they can be seen from satellites. Scientists are making different assumptions: some say that these are just large accumulations of luminescent organisms; others say that this is impossible, because the concentration of bacteria in the water must be simply unimaginable for the glow to be visible from a satellite. Either way, there is no exact answer to this question yet. The mystery remains unsolved.
Top 25: Deep-sea mysteries and oddities that will boggle your mind
More people have been to the moon than to the deepest parts of our planet. The oceans, which cover 70 percent of the Earth, are the largest habitats in the world, yet we have only been able to explore about 1 percent of the bottom of all the oceans. The deep blue waters of the oceans harbor mysteries, and in this list we will try to make sense of some of them. We present to you twenty-five deep-sea mysteries and oddities that will amaze your imagination.
25. Herring King (Giant Oarfish) The body length of the herring king, which is the source of many sea snake sightings, can reach 11 meters. Its body length exceeds the length of its container. These essentially unstudied creatures previously seemed to be very rare, but they have now been found to be more common than previously thought.
24. Deep-sea photosynthesis There may be no sunlight at the bottom of the ocean, but some bacteria near hydrothermal vents use the dark red glow of the vents to photosynthesize and produce food for themselves. Scientists are still trying to figure out how this is possible.
23. Upsweep Sweep
The National Oceanic and Atmospheric Administration (NOAA) listens for sounds in oceans around the world. Most of them have been identified, but scientists are still unable to decipher the sound known as the Upsweep signal. This signal is several seconds of narrow-band, upward sweeping sweep signals. This sound is most often heard in the spring and fall.
22. Vampire Squid The Vampire Squid is a strange creature that produces its own light through glowing tentacle tips and spots on its sides. If disturbed, it can squirt out ink that glows.
21. Baltic Sea Anomaly The Baltic Sea Anomaly is an object in the Baltic Sea that still remains a mystery. Some speculate that it may refer to a period before the Ice Age, or it may be a Nazi anti-submarine device. Oddly enough, the diver’s electrical equipment stops working within 200 meters of this object, and the strong radio signal almost completely disappears in its immediate vicinity.
20. The snailfish The snailfish is the creature that most of us picture when it comes to deep-sea fish. The whippersnapper has a spur on its forehead, the end of which glows. It uses this light to lure its prey before grabbing it with its overly large mouth.
19. Bloop The bloop is another sound recorded by the National Oceanic and Atmospheric Administration in the Pacific Ocean. This sound is unique in that it was recorded by monitoring stations located 5,000 kilometers apart. So far, the National Oceanic and Atmospheric Administration has concluded that it was the sound of ice breaking away from a glacier, however, some scientists still speculate that it could have been the sound made by a huge sea creature.
18. Lost Submarines In 1968 four countries lost submarines: the U.S., Russia, Israel and France, a loss which cannot be explained to this day. Some speculate that the loss may have been an attempt by governments to cover up (at least in the case of the U.S.) the misses of nuclear warhead torpedoes.
17. Sea Gooseberry This species of gooseberry, nicknamed the sea gooseberry, has long sticky tentacles with which it catches small particles and animals. Unlike most jellyfish, it does not sting.
16. Disappearances Since its founding, the aviation industry has suffered many unexplained losses of aircraft at sea. The most recent of these losses was the Malaysian Airlines MH370. One of the industry’s most famous pioneers, Amelia Earhart, also disappeared mysteriously. She and her co-pilot, Fred Noonan, disappeared while flying over the Pacific Ocean in 1937. Millions of dollars were spent searching for her plane, but all attempts were unsuccessful. Popular theories include the suggestion that she ran out of fuel or that the plane was shot down by the Japanese military for alleged espionage.
15. Bacteria living in the depths of the seafloor One might assume that there could be nothing alive under the seafloor, but scientists have recently discovered bacteria living at a depth of about 300 meters. The bacteria, discovered while drilling through the Earth’s crust on the seafloor, fed on sediments many millions of years old.
14. Magnapinna (Bigfin Squid) Deep-sea squid of the genus Magnapinna, which resembles a dinghy rudder, was first discovered off the coast of Hawaii in the mid-2000s. It was almost impossible to photograph. Its body length, including tentacles, can reach 5 meters.
13. Fighting snail Snails Snails are not the first animals one would think of when talking about armor. However, a recently discovered and as yet unnamed species of snail in the Indian Ocean uses iron compounds in the form of scales to protect its fleshy legs. The U.S. Army is even studying this snail to see if it can improve its combat armor.
Worms near hydrothermal vents have no mouths or digestive systems. Moreover, they look like long pencil cases for lipstick. Thus, they rely on symbiosis with bacteria, which use chemical compounds to produce food that the worms can ingest.
11. The squid of the Gonatus Onyx species Using hooks under its tentacles, the squid of the Gonatus Onyx species holds its clutch of eggs for many months before its young hatch. Now that’s a truly caring parent!
10. Deep-sea Corals Many people think of coral reefs as tropical installations. However, scientists have recently discovered deep-sea corals that live in cold waters, but most have been destroyed by trawlers. At this point, scientists are in the primary stages of studying them, however, they have discovered a reef off the Norwegian coast that stretches for 100 square kilometers.
9. Giant Leptocephalus Giganteus Only two individuals of a species of eelgrass called the giant leptocephalus have ever been found, and they were both larvae. The first (found off the coast of South Africa) was 184 centimeters long, which means that an adult can be over 21 meters long.
8. The Platypus Shark The Platypus Shark is sometimes called a living fossil because of its primitive characteristics. However, it is a fairly rare animal that catches its prey by bending its body and making a forward dash like a snake.
7. The mysterious Mariana Trench shark While exploring the sea life at the bottom of the very deep Suruga Bay, Japanese scientists set up a bait to attract marine life. They didn’t expect to see a shark with a body length of at least 9 meters among them. Some scientists say that it was the largest recorded representative of the species of Pacific polar shark (the third largest), but others consider it proof that the largest and prehistoric megalodon still exists today.
6. Underwater Whirlpools An underwater whirlpool can be compared to an underwater tornado. Such whirlpools exist over some underwater vents. Under certain conditions, they can break off and swirl around like flying saucers, carrying heat, chemicals, and organisms all over the ocean. This is similar to the way the wind carries dandelion spores.
5. Giant Squid The giant squid, a huge sea creature, has made a lot of noise in the media, but in reality, very little is known about it. His body is 13 meters long and weighs up to 450 kilograms. The first living giant squid was caught on camera in July 2012.
4. the Antarctic giant squid (Colossal Squid) However, if you thought that squids could no longer be larger than a giant squid, you were wrong. Even less is known about the Antarctic giant squid, whose eyes are bigger than your hand. This squid predominantly lives in the waters surrounding Antarctica. At the end of each of its tentacles are 25 rotating hooks.
3. Sulfur Lake Within the Pacific Ring of Fire is a lake. This lake is special because it is underwater and consists of molten sulfur. The lake is located 400 meters below sea level and its area is teeming with marine life, including crabs and shrimp, specially adapted for life in such conditions.
2. the Idiacanth or Dragonfish The bioluminescent Idiacanth, which shoots a beam of light from under each eye, is the only animal that can see the red light of other Idiacanthuses. It is the most reliable secret code!
1. The Macropinna Microstoma is a fish with a very rare and practically unexplored body composition: its head is covered by a transparent dome filled with liquid. In addition, its barrel-like eyes look upwards (through the dome). If she is in a horizontal position in the water, her eyes may look forward as she changes position.
