What is the largest sea in the world?

The largest sea in the world is the Coral Sea.

Coral Sea: With a total area of ??4.791 million square kilometers, it is the largest sea in the world, equivalent to half of China's land area. The Coral Sea is located in the southwestern Pacific Ocean, east of Australia and New Guinea, west of New Caledonia and the New Hebrides, and south of the Solomon Islands. It is approximately 2,250 kilometers long from north to south and 2,414 kilometers wide from east to west. It is connected to the Tasman Sea to the south, the Solomon Sea to the north, the Pacific Ocean to the east, and the Arafura Sea to the west via the Torres Strait.

The Coral Sea is named after the large number of coral reefs, the most famous of which is the Great Barrier Reef. The world-famous Great Barrier Reef is located in this sea area. Like a fortress, it stretches from the Torres Strait to just south of the Tropic of Capricorn for 2,400 kilometers from north to south, and is about 2 to 150 kilometers wide from east to west, with a total area of ??80,000 square kilometers. It is the largest coral body in the world. Most of them are submerged underwater and become reefs. Only a few tops are exposed out of the water and become coral islands, which is an obstacle to transportation.
