Ocean

 The ocean is a wonderful space. We think we know it well, but the oceans hide a lot from us. Today I will tell you some interesting facts about them.

1. We all know that the oceans are salty, but did you know that if salt were separated from them, there would be enough salt to cover the entire surface of the earth with a 166-meter layer?


2. We think that Oceans make up about 70% of the earth's surface. But if the depth of the oceans was included in these calculations (it was not included before), the ocean surface would increase to 99% of the earth's surface.


3. It's surprising how little we know about the ocean. About 90% of marine species are still undiscovered. There are so many of them that scientists discover a new species on average every week.


 

4. We have more detailed maps and studies of the surface of Mars than of the deep sea. Researching and observing the depths of the oceans, contrary to appearances, is much more expensive than sending satellites into space.

    Are oceans becoming more or less salty with time? The Baltic Sea, for example, is getting less salty.

Barreleye- fish with transparent head

Obraz
Barreleye is a fish that lives at great depths. Her transparent forehead makes her stand out. You can easily see her eyeballs through it. Until 2009, scientists thought that fish could only see above themselves, but Bruce Robison and Kim Reisenbichler proved that their eyes are movable.  Like most deep-water fish, changes in their appearance serve to adapt to life at depth. In their case, to notice food floating above them e.g. siphonophores, and to capture more light.  The eyes are light green, probably to attract the attention of victims. They are surrounded by a space filled with a transparent liquid. The fish's head is very delicate and only one of many attempts to catch the fish without damage was successful. One of their most common foods is jelly. They reach up to 10 m in length. They have many stinging tentacles. The space above the eyes protects the fish from burns. I believe life in the ocean is as exciting as life beyond Earth. Humans have only discovered 5% of the geog

Strawberry Squid

Obraz
Strawberry squids are one of the most beautiful ocean creatures I know. It is for sure because of its shining pink skin  which they owe to photophores. We already know ( from the last blog about Barreleye- a fish with a transparent head) that nothing in the ocean is accidental. The ability to bioluminescence is mainly used for communication with other ocean creatures. Another fantastic thing about them is their eyes in two different sizes. The larger yellow eye helps the squid see the shadows of prey swimming above them. The smaller blue eye helps the squid look for light reflecting off other glowing creatures below. Another adaptation is that they swim at an angle, so they can use both eyes. They appear at a maximum depth of 1000 meters and it's during the day when they hide from predators but at night they can be found closer to the surface. Thank you for reading !!!

Blobfish

Obraz
 Blobfish is a very unfavorable looking fish. When I saw her for the first time, I had many questions. Fish lives at great depths, from 600 to 1,200 m. The pressure underwater at such depth is so great that it would instantly crush human organs. The conditions in which it lives make it difficult to study its species. The fish is small but weighs a lot. It measures 30 cm and weighs as much as 9 kg. It feeds on small organisms found in its environment. It has no teeth. The fish's body is a gelatinous mass.   And now the most important thing, why does the Fish look this way? The answer is not complicated. Fish are adapted to life under enormous pressure. It is what gives her body its shape. A fish pulled out of the depths loses its properties. The nets dragged for more than a kilometer to the surface destroy their bodies. We have very few photos that show us what they look like in their natural environment. However, it is enough to say that they look like completely norma
