CATDOLL : CATDOLL: The world's largest

1. The world's largest sea

The Sea of ​​Marmara is 270 kilometers long from east to west and about 70 kilometers wide from north to south, with an area of ​​11,000 square kilometers, which is only equivalent to 4.5 times the size of my country's Taihu Lake. It is the smallest sea in the world.

The largest and deepest sea - Coral Sea

70% of the earth's surface is covered by water, so the earth is also called the "water planet". Most of this 70% of water is oceans, and the sea is only a part of it. The size and depth of the seas around the world are different. The largest and deepest sea is the Coral Sea in the South Pacific. There are groups of sharks living in the Coral Sea, so the Coral Sea is also called the "Shark Sea".

The total area of ​​the Coral Sea is 479.1 square kilometers, which is equivalent to half of China's land area. It is surrounded by the Australian continent to the west, the Tasman Sea to the south, and the New Hebrides, the Solomon Islands, and New Guinea (also known as Irian Island) to the northeast. From a geographical point of view, it is the largest sea in the South Pacific. The seabed topography of the Coral Sea is roughly inclined from west to east. The water depth in most places is 3,000-4,000 meters, and the deepest is 9,174 meters. Therefore, it is also the deepest sea in the world. The Coral Sea is located near the equator, so its water temperature is also very high. The water temperature is above 20℃ throughout the year, and even exceeds 28℃ in the hottest month. There are almost no rivers flowing into the Coral Sea, which is one of the reasons why the water quality of the Coral Sea is less polluted. The sea water here is clear and transparent, and there is sufficient light underwater for various coral polyps to survive. At the same time, the salinity of the sea water is generally between 27-38%, which is also an ideal environment for the life of coral polyps. Therefore, whether on the continental shelf in the sea or on the shallows by the sea, there are a large number of coral polyps everywhere. Over time, it gradually developed into numerous coral reefs of various shapes. These coral reefs would emerge from the sea at low tide, forming a magnificent spectacle unique to tropical waters, hence the name "Coral Sea".

We already know that coral reefs are found almost everywhere in the Coral Sea. The largest of these coral reefs is the Great Barrier Reef, which floats in the sea like a huge colorful ring. At the same time, there are often many colorful, rich and active creatures floating around the reefs, which contrast with the colorful coral reefs and present a bizarre fairy tale world.

The world's largest and deepest ocean

Among the world's oceans, only three have an area of ​​more than 3 million square kilometers, and only the Coral Sea has an area of ​​more than 4 million square kilometers. Its total area reaches 4.791 million square kilometers, making it the largest sea in the world. The Coral Sea is a sea of ​​the South Pacific. It is surrounded by the Australian continent to the west, the Tasman Sea to the south, and the New Hebrides, Solomon Islands, and New Guinea (Irian Island) to the northeast. Most of the seabed of the Coral Sea is 3,000-4,000 meters deep, and the deepest point is 9,174 meters, making it the deepest sea in the world.

The deepest sea in the world is the Coral Sea in the South Pacific, with a maximum depth of 9,174 meters; the sea with the highest average depth is the Scotia Sea near Antarctica, with an average depth of 3,400 meters; the deepest sea in the world is the Mariana Trench

2. Which is the largest sea in the world?

The world's largest sea

The largest sea in the world is the Coral Sea, which is located in the southern hemisphere. It is close to the northeast coast of the Australian continent in the west, surrounded by Irian Island, New Britain Island, New Hebrides Islands, and Solomon Islands in the north and east, and connected to the Tasman Sea on the edge of the Pacific Ocean in the south. The sea area is very vast, with an area of ​​4.793 million square kilometers.

3. The largest sea in the world

The Coral Sea on the east side of Australia is also known as the Solomon Sea.

The largest sea in the world is a marginal sea of ​​the Pacific Ocean, the Coral Sea. Its southern part is adjacent to the Heisman Sea, another marginal sea of ​​the Pacific Ocean. Its northern and eastern edges are surrounded by New Britain Island, Irian Island, Solomon Islands, New Brides Islands, etc.; its western edge is close to the northeast coast of the Australian continent. It is one quarter larger than the Arabian Sea, the second largest sea in the world. The Coral Sea is also called the Solomon Sea.

The Coral Sea is not only famous for its size, but also for the well-developed coral reef structure in the sea; hence the name. Its seabed slopes roughly from west to east. It is interlaced with sea basins, shoals and submarine mountains, and there are many places where the sea depth is about 3,000-4,500 meters. The total volume of seawater is 11.47 million cubic kilometers, 9% more than the Arabian Sea and 43 times larger than the East China Sea in my country.

However, this animal is one of the most dangerous animals in the ocean. They are active in the Pacific and Indian Oceans. They are highly toxic and release tetrodotoxin when threatened. This toxin attacks the nervous system and causes death in just 4-6 hours. The lethal dose is only 8 microliters per kilogram, which means that half a milliliter of the toxin of the blue-ringed octopus is enough to kill a medium-sized person.
