How many species of marine life are there in the world, and how many species of marine life are ther

There are a total of 210 species of creatures under the sea. It is currently knownMarine lifeThere are 210,000 species, and the actual number is expected to be more than 10 times that number, or 2.1 million.

A total of 20,278 species of marine organisms have been recorded in the waters under the jurisdiction of China, and the marine organisms belong to 5 biological kingdoms and 44 biological phyla, of which the animal kingdom has the most species, with 12,794 species, and the prokaryotic kingdom has the least, with 229 species.

Scientists around the world are currently engaged in an unprecedented collaborative programme to identify and compile inventories of all marine life. How many species of life are there in the ocean?

A survey that synthesizes global ocean data has been released. There are currently 15,304 registered species of marine fish, and it is estimated that there will be about 20,000 species of marine fish in the end. There are currently 210,000 known species of marine life, and the actual number is expected to be more than 10 times that number, or 2.1 million species.

It is estimated that there are between 240,000 and 360,000 known species of marine life. However, this is only a rough estimate, and in fact the diversity of marine life may be much higher than this number. Due to the vastness and complexity of the marine environment, there are many marine organisms that have yet to be discovered, described, and classified.

Marine life is diverse, ranging from tiny plankton to large cetaceans. The diversity of marine life is very important and plays a key role in maintaining the stability and balance of marine ecosystems.

Scientists are constantly conducting marine surveys and studies to discover new species of marine life and to learn about their ecology, physiology and friendship. With advances in technology and science, we can hopefully better understand and protect marine biodiversity.

What kind of sea life is there in the world, there are thousands of species of sea life in this world, there are some sharks that I am more common, and sea cucumbers also have a lot of shots, which are rarely paid attention to. Let me share what marine life is in the world, come and take a look!

1. Sharks

There are tens of thousands of species of marine life, the most common of which are sharks. Sharks are long spindle-shaped, with gill slits on both sides of the head, sharp teeth, no swim bladder, fierce by nature, often in groups, sharks belong to the body fertilized animals, juveniles will hatch and grow in the abdomen of female sharks.

2. Lobster

Lobsters are marine creatures with a thick cephalothorax and a hard shell with a body length of about 30 centimeters. In the first year of life, lobsters will undergo ten shell changes, while mature lobsters will only change their shells once every three years, and the teeth of lobsters grow in the stomach, and there are no teeth in the mouth.

3. Sea cucumber

Sea cucumbers are marine creatures. In the world, there are more than 900 varieties of sea cucumbers, and in China, there are only more than 140 varieties, among which the more common varieties are spiny cucumber and plum ginseng. Moreover, it is distributed in the Yellow Sea and Bohai Sea, and plum ginseng is distributed in the coastal areas of Hainan.

4. Sea snakes

Sea snakes are marine creatures, belonging to the cobra family, according to their diving time can be divided into three types, namely shallow sea snakes, deep water sea snakes and aquatic sea snakes, of which shallow sea snakes can only dive for 30 minutes each time, deep water sea snakes can dive for two hours, and aquatic sea snakes can move freely in the water.

1. Jiawan porpoise

Details: Due to the narrow habitat range and the habit of warm water areas, fishermen can easily trap them in nets when fishing, coupled with environmental pollution and malicious killing, which has become the main reason for the extinction of the Gulf porpoise.

2. Dugong

Details: Dugongs have the title of "mermaids", which are very similar to manatees, and are mainly distributed in tropical sea areas. Dugongs are very slow to move, and have high requirements for water quality, and are prone to problems such as pneumonia and ** disease, coupled with human hunting, resulting in dugongs gradually becoming endangered creatures.

3. Bluefin tuna

Details: Bluefin tuna is mainly distributed in the Pacific Ocean and the Atlantic Ocean, and they inhabit different depths and prefer to move in groups. Bluefin tuna was listed for conservation in 2009 due to overfishing, and if left unchecked, it will soon become extinct.

4. Blue whale

Details: The blue whale is currently the largest creature in the world, with a daily diet of more than 4 tons, and its heaviest weight can reach more than 200 tons. Due to the frequent hunting in the last century, blue whales are an endangered species, and as of now, there are fewer than 50 blue whales in the world.

5. Tortoiseshell

Details: The hawksbill turtle is a sea turtle, its body size is relatively large, generally more than a meter, and the forehead is also distributed with scales, due to overfishing makes the hawksbill turtle an endangered marine animal, in China's waters are almost impossible to see this turtle.

210,000 species.

There are currently 210,000 known species of marine life, and the actual number is expected to be more than double that number, or 210,000 species.

A total of 2,278 species of marine organisms have been recorded in the waters under the jurisdiction of China, and the marine organisms belong to 5 biological kingdoms and 44 biological phyla, of which the animal kingdom has the largest number of species, with 12,794 species, and the prokaryotic kingdom has the least, with 229 species.
