Scientists can tell a lot of interesting things about distant planets, but what is at the depths of the oceans remains a big mystery even for them. The oceans have been studied by only 2% and the researchers even joke that they are more familiar with the far side of the Moon than with the watery expanses of our planet. At a depth of several kilometers, many animals unknown to science live. Since there is strong pressure on research equipment at great depths, it is very difficult for scientists to study them. Usually, they learn about deep-sea creatures by extracting them from the inside of predators - at the moment this is the most affordable way. But recently, for the first time in history, scientists have managed to film a glass octopus (Vitreledonella richardi), almost the entire body of which is transparent. According to the authors of the study, this animal has no analogues in the world. Let's find out more about it and watch an amazing video?
Interesting fact: information about unusual octopuses and the filmed video was published on the Schmidt Ocean Institute website. It is a non-profit foundation that was founded in 2019 by former Google CEO Eric Schmidt and his wife. The organization is engaged in the development of oceanographic research - as mentioned above, this is a very difficult business.
The most mysterious octopuses
It is reported that the amazing video was filmed in the Phoenix Islands, which are located near the Pacific state of Kiribati. For the survey, an underwater robot SuBastian was used, which was developed by scientists from the Schmidt Ocean Institute and is capable of diving to a depth of 4,500 meters. If not for him, scientists would hardly have been able to observe the octopus, which usually lives at a depth of 1 kilometer. Such creatures never rise to the surface and the only chance to study them is to find the remains of their bodies inside predators.
SuBastian underwater robot
The octopus that was captured on video is called "glass". His body is almost completely transparent - only rectangular eyes are visible, as well as parts of the nervous and digestive systems. It is because of this that scientists say that this animal has no analogues. The body length of these creatures almost does not exceed 1.5 meters. Scientists know little about their lifestyle. Researchers only know that males use one of the tentacles for fertilization. And females, most likely, spend a lot of time next to eggs - because of the cold water of the ocean depths, they develop very slowly. Sometimes this process can take several years.
Transparent octopus video
As for octopuses, they most likely need transparency to protect them from underwater predators. As mentioned above, creatures living at great depths are often found inside predators on the surface. And this means that in the depths of the oceans it is very dangerous and all means are good as protection. However, maybe octopuses use their invisibility as a disguise to catch their food without any problems. Be that as it may, in all this, scientists have yet to figure out. It remains to be hoped that the SuBastian robot and other devices will help them with this.
Ocean deep dwellers
In addition to the transparent octopus, scientists managed to photograph several more amazing animals. In the video below, you can see whale sharks, whose body length reaches 12 meters. And it's just great that the video was shot in high definition.Indeed, sometimes such videos are of such disgusting quality that little can be seen on them. Here's an example - can you understand how killer whales hunt sharks?

Finally, I would like to note that octopuses are considered one of the smartest animals in the world. Some researchers even suggest that they came to our planet from distant planets. O
