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.

Bioluminescent Algae

Obraz
Glowing algae is a beautiful occurrence.  They are made of groups of tiny algae. When their surroundings move, e.g. when waves or when they touch the shore, they activate their defense mechanism.  Many chemical processes occur in their bodies, resulting in beautiful blue light. Lucefyrin molecules are responsible for them. Bioillumination is a Phenomenon experienced by over 80% of deep-sea animals.  Fireflies are an example of Bioillumination on the surface.  In California, the water turns rusty, but at night it shows its beautiful face, this happens every few years - red tide. Some of them are dangerous in high concentrations and marine organisms stay away from them. However, they attract people who are unaware of the danger. Swimming in water with algae results in skin infection. (323) Plankton Light The Sea In Wales: 'It Really Is Something Magical' - YouTube What Is Bioluminescent Algae? (treehugger.com)

Yeti Crab

Obraz
Yeti crab is another deep sea creature that I will write about today.  What catches my eye is the unusual hair covering the animal.  Like every deep-sea animal, their unusual appearance conceals some really useful adaptations.  In this case, crabs grow bacteria on silk hairs, which they can eat.  These crabs are completely blind, so hunting prey would be completely impossible.   Yeti crabs are small (up to 15 cm). They settle near hydrothermal vents (they release warm water). Bacteria grown by crabs neutralize poisonous substances found in water from hydrothermal vents.  Some bacteria feed on such compounds.  Crabs form large clusters, which increases their body temperature. “It was almost like a sight from another planet.  The yeti crabs were literally in heaps around the hydrothermal vents — in densities in up to 600 per square meter — and all jostling and writhing around to get the best position in the hydro...
