It is difficult to imagine a more ancient formation on planet Earth than the ocean. From the once huge, global ocean of Tethys over time, four different reservoirs stood out, the largest of which is called the Pacific Ocean.
Loud about the Pacific
The Pacific Ocean is a record holder in many respects. It is huge (occupies a third of the earth's surface) and is not at all quiet. And they called him so with the light hand of Fernand Magellan, who was the first to have the courage to completely cross this reservoir, and at the same time he was lucky not to get into the storm. But do not flatter yourself: these waters can be very dangerous due to air currents that walk over their surface.
In addition, the Pacific Ocean is the
Earth’s greatest
ocean, twice the size of the Atlantic counterpart. One fact can give an idea of its size: approximately half of the total population of the earth (50 states) lives on the shores of this amazing reservoir.
The Pacific Ocean is the deepest in the world. It is in its thickness that the famous Mariana Trench is located, the depth of which reaches 11 km. This depression is the most significant on our planet. Besides him, there is another 10-kilometer Philippine trench.
The bottom of the Pacific Ocean has one of the most difficult reliefs, and the number of islands in its territory reaches 10 thousand.
Despite the depth, the Pacific Ocean is called the warmest among others. The fact is that it has the shape of an oval, which expands at the equator, which explains the warmth of its waters.
The ocean lies on a huge Pacific plate, between both Americas, Antarctica and Australia. It crosses almost all the climatic zones of the Earth, so the Pacific Ocean, the organic world of a huge reservoir, is worthy of attention. Indeed, half of the total mass of organisms living in the oceans lives in it.
Organics of the largest ocean
The organic world of the Pacific is rather difficult to describe briefly. It is especially rich in a variety of life forms in tropical and equatorial latitudes. In the north of the oldest of the oceans, schools of salmon fish are moving en masse. Waters off the coast of South America abound in phyto- and zooplankton, as well as anchovies, horse mackerel and mackerel. Coral reefs are teeming with diverse animals: sea urchins, various mollusks. Huge whales, octopuses, sharks, crabs and squids splash in the deep water. A huge clam called tridacna, which weighs about 250 kilograms, is also hiding in the dark bulk of the Pacific Ocean.
Legendary kelp and giant microcystis stand out from the plant world of the oceanic depths. The whole organic world of the Pacific
diverse, and sometimes unique. For example, the only reef on the planet created by living organisms is located off the Australian coast, in the tropics of the Pacific Ocean. This ridge can be compared in size to the Ural Mountains.
Fauna: characteristic representatives
Given that the Pacific Ocean and its inhabitants appeared long before the development of human civilization, the depths of this reservoir are fraught with unprecedented species diversity. And some representatives of the organic world of the Pacific Ocean long ago became extinct in other places of the World Water Area. In its thickness are found almost all species of commercial fish, huge mammals, such as whales, for example, sperm whales. Endemic species also exist: sea urchins, beavers and seals. The abundance of zooplankton, shellfish, oysters, crabs, jellyfish, squid and mussels allows us to hope that the rest of the inhabitants are fully provided with food. At the equator, sharks and sailboats live. Often found tuna.
The scuba diver’s nightmare lives in comfort here: a huge clam is a tridacna.
In principle, the Pacific Ocean, the organic world of a reservoir in particular, depends on the amount of phytoplankton. Where it is enough, the rest of life develops there: zooplankton, mollusks, squids, whales and other representatives of the organic world.
Seals
The features of the organic world of the Pacific Ocean are that no matter how many climatic zones affect its thickness, but one mammal invariably is the inhabitant of only this reservoir. It is called a fur seal. This animal is a cross between a seal and a sea lion. A fur seal is covered with stiff bristles; it has ears that close when immersed in water. Fins or flippers help him swim, which even on land help the cat to move. Females dive to a depth of 60 meters, catching fish and squid. They hunt mainly at night. The thick fat layer saves the life of fur seals, in those difficult times when mammals can not find food. He warms and nourishes these unique animals.
Flocks of fur seals migrate several times a year: in the spring, on the islands of the Bering Sea, mammals have offspring, and they prefer to winter in the open sea. Manages mammals and guards a flock of experienced leader.
Tridacna: Pacific Horror
Is a creature living at a depth of about 100 meters under water, a natural filter and a pearl producer - is it a myth or a reality? This is absolutely true. Huge mollusks, whose weight reaches half a ton, do live in the thickness of the Pacific Ocean, near the Philippines. This creature is capable of passing masses of water through itself, thus being saturated with plankton and oxygen. Mollusks can be a danger to the diver: after holding the human limb, they deprive him of a chance to float to the surface. Like any other type of mollusk, tridacna give birth to pearls. The story enthusiastically speaks of a pearl weighing about 7 kilograms, having the appearance of a man dressed in a turban.
Unfortunately, this unique mollusk gradually disappears from the face of the earth. They simply eat it. Sometimes the meat of an ocean inhabitant is cut right under the water. Souvenirs, which are in demand among tourists, are also cut from shells. Tridacna looks great in aquariums and artificial ponds. In addition to aesthetic appeal, it qualitatively purifies water.
Diverse flora
The Pacific Ocean, whose organic world is incredibly diverse, is unthinkable without vegetation. The density and fullness of it is again regulated by the climatic zone. For example, coral reefs and mangroves are common in the tropics. As for phytoplankton, it is mainly represented by algae species such as diatoms and peridinea. About what the organic world in the Pacific Ocean is at the bottom, a figure characterizing the amount of bottom algae can tell: 4 thousand species. In cold waters there is an accumulation of kelp and kelp.
Laminaria: More Than Seaweed
Beautiful and powerful Pacific Ocean. Its organic world is filled with many creatures and plants, among which there is the famous kelp. This algae is colloquially called sea kale. It reaches a length of 20 meters. The particular value of this ocean product is that kelp is abundant in iodine. This allows the human body to be fed with this microelement, which will avoid problems with the thyroid gland in the future.
In addition, iodine is an excellent disinfectant. From kelp make popular salads and canned goods. Also, kelp is actively used in the medical industry: medicines are made from it, it is used for pathologies of pregnant women and for obstetric care. Cosmetics based on this ocean resident promote skin regeneration and weight loss.
We have described the organic world of the Pacific as briefly as possible. Although, of course, this is the tip of the iceberg, since the depths of the "not quiet" pond store a lot of unsolved mysteries.
