The research submarine Nautilus records a strange jellyfish
(6) | 16/11/2017 | Translate: The research vessel "Nautilus" recorded in very great depth a rare jellyfish Deepstaria, near the Revillagigedo Islands in the Pacific Ocean.
The jellyfish impressed researchers with the transforming abilities, as her body uncomfortably and create various shapes with the water stream.
A giant jellyfish During a mission in November 2021, the Doc Ricketts submarine of the Monterey Bay Aquarium Research Institute (GOOD) managed to film a giant jellyfish ghost (Stygiomedusa gigantea) at great depths in the Gulf of California. The jellyfish has a bell more than one meter wide and ribs like ribs that can extend over ten meters. In more than a century, only a hundred of these jellyfish have been observed, especially because of the inaccessible depth at which they live.- Ride a speedboat dolphin The Seabreacher is a speed boat / submarine car boat, shape-based shape of a dolphin. The movement of water also mimics the movements of a dolphin, and can dive and a few meters below the surface.
- A quadruple waterspout Tourists on one of the islands in the Gulf of Thailand recorded on video a rare quadruple water siphon. A ydatoloutho is an intense vortex column (usually appears as a funnel shaped cloud) that occurs over a body of water. Marine tornadoes or ydrosifones, are tornadoes that occur over a water body. The ydrosifones is much weaker than tornadoes, last few minutes, while the speed of their movement from one point to another is much slower.
- The jellyfish-like firework Scientists at the research submarine Nautilus, They recorded a strange jellyfish in the Revillagigedo Archipelago, near Baja California Mexico. At a depth of 1225 meters, this jellyfish looked like a big firework when the submarine lights fell on it. According to the group, this is a jellyfish Halitrephes Maasi.
- The transparent octopus This is a rare video of him "glass octopus" (Vitreledonella richardi), an almost transparent octopus whose only visible features are the optic nerve, the eyes and the digestive system. The existence of this transparent octopus has been known for more than 100 years, but this is the first time it has been recorded on video. Scientists filmed it in depth near the Phoenix Islands, Northeast of Sydney in Australia.
- Demonstration of the pressure difference during a dive A nice example of how the water pressure increases as the depth increases. The weight of the water above the diver puts pressure on his body. The deeper the diver sinks, the more water he has on him and the more pressure he has on his body. The pressure that a diver experiences at a certain depth is the sum of all the pressures on him, both water and air.
- How a hydrofoil moves The Hydrofoil or commercially called flying dolphin, or hydrophilic, is a type of ship that uses fins under its hull called water slides. Above a certain speed the main part of the boat exits the surface of the water, resulting in zero friction to develop greater speed. The boat in the video is a Boeing 929, which moves to the island of Tanegashima in Japan.
- Boat against an enormous wave In Nias Island, Indonesia, a marine vessel is ungovernable in the water after the storm previously cut the anchor of. Then, a huge wave devouring.
- A sophisticated rescue boat The new rescue boat "Shannon" the Royal National Institute for survival craft (RNLI) in England, It has water turbines instead of propellers, something that makes it extremely agile. You can start and stop very shallow depth, while it is impossible to tip over the water. It is also equipped with special shock absorber seats.
- White shark tries to bite a researcher A large white shark pops out of the water and trying to bite a researcher who stands on the edge of a platform on a boat. The incident occurred off the coast of Cape Cod. Massachusetts.
- Dolphin swims with the tide on the bow of a boat Tomislav Petric filmed a dolphin swimming under the bow of a boat traveling from Croatia in the clear Adriatic Sea waters. As the boat moves forward, causing a wave of water in front of the. Placing his body in this wave, the dolphin moves like surfer without spends his energy.
- Volcano under water Near the Solomon Islands in the Pacific Ocean, submarine volcano Kavachi detonates under water. The volcano has created three times volcanic islands lava (2003,2004,2007), but the islands could not stand the sea currents and dissolved.
- The two mating anglerfish first recorded on video The deep-sea monkfish are strange creatures very rarely observed in their natural environment. Less than 6 have been recorded on video by diving deep. For the first time, The Kirsten and researchers Joachim Jakobsen recorded at a depth of 800 meters to two Monkfish mate.
- 100 birds dive simultaneously in the water Galapagos Islands, a large flock of blue Sula simultaneously dive into the water to catch fish. To catch their prey, blue Sula can dive up to 20 meters deep and stay 30 seconds under water. Blue Sula is puffin mainly feeds on small fish (sardines, anchovies, etc.).
- underwater hiking On February 2, 2018 in the park Rio da Prata, Brazil, the rains caused the Olho D'Água River to overflow, who sank a hiking trail. The clear water has created a spectacular underwater landscape. A rare phenomenon lasted only one day.
