Pacific Ocean

Most is the huge Pacific Ocean. We have already mentioned that in his area, he surpasses all the land. By its very nature it has much in common with the Indian Ocean. And the boundary between them in their southern latitudes is purely a formality. The one who first meets the ocean can not help but marvel at the sight of the vastness of the water, which before it opens. Just imagine, the Pacific Ocean stretches from East to West by 19,000 kilometers. And from north to south it is located in the space of 16 thousand kilometers! It runs parallel to almost all natural zones of the earth. The originality of the Pacific is composed of the structure and topography of its bottom, climate and water, as well as the life that has evolved and exists in it. As many mentioned above, the ocean floor uneven. It represents the land surface, with its rugged terrain. As well as on land there are some plains, valleys and mountains. They constitute different levels, like different floors of a multistory building. And for every such story has its conditions for living organisms. For example, organisms that live on the top floor, near the ocean surface, can not fall to the ground floor. There will be live very different organisms, and grow other plants. Life of the Pacific are very diverse. It accounts for more than 50 percent of all living things from the number of the oceans. From plants distributed mainly single-celled organisms, which are the Pacific Ocean has more than 1300 different species. And about half of these species relates to the microscopic zhgutikonosnym armored algae. Somewhat less - to the microscopic algae yellowish, the outer envelope which consists of two halves of flint. And anyway, most of the vegetation is in relatively shallow waters of the Pacific Ocean. Although benthic vegetation too numerous. It has about 4 thousand species of algae and species of flowering until '29 ("seaweed"). In cold and temperate zones of the Pacific Ocean is the development of kelp, especially from the group of Laminaria. These large algae are eaten by man and used as livestock feed. It is also used as a drug-dietary means, better known under the name "sea kale". Widespread in the Pacific Ocean have algae (especially calcareous red algae), which influence the formation of reefs. Fauna of the Pacific Ocean are also much richer and more varied than in other oceans. Particularly rich in tropical zone. In the seas of the Indonesian archipelago known for more than two thousand species of fish, whereas in the northern seas - the Sea of ??Okhotsk and the Bering Sea - there are only about 300. But even in these seas, the number of species of fish twice in the seas with the same climatic conditions, but related to other oceans. An interesting fact, which belongs to the fauna of the Pacific Ocean, is the presence of a very ancient species of marine animals. This is primarily a large number of ancient species of sea urchins, horseshoe crabs primitive genera, some very ancient fish, which has not survived in other oceans, such as Jordan. In addition, in the Pacific inhabited by 95 per cent of salmon. Only in the Pacific live representatives of the class pofonogor. For many wildlife species peculiar to the Pacific gigantism. In the northern part of the ocean known giant mussels and oysters. And in the equatorial zone inhabited by the largest bivalve-tridakna. His weight is 300 pounds. Among mammals, living only in the Pacific Ocean, called the dugong, seals, sea lions, sea otter. In the other oceans, they are missing.
