What are the common marine creatures and what are the creatures in the ocean?

There are a total of 210 species of creatures under the sea. There are currently 210,000 known species of marine life, and the actual number is estimated to be more than 10 times that number, or 2.1 million species.

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.

Marine life refers to the species that are living in the ocean, including marine animals, marine plants, microorganisms and viruses, among which marine animals include invertebrates and vertebrates. Invertebrates include a variety of snails and shellfish. Vertebrates include a variety of fish and large marine animals such as red starfish, whales, sharks, etc.

Marine organisms refer to all kinds of organisms in the ocean, including marine animals, marine plants, microorganisms and viruses. Such as whales, sharks, shellfish, shrimp, crabs, etc.

The plants in the sea are: cyanobacteria, red algae, green algae, spirulina, brown algae, coral, kelp, etc. The animals of the sea are:

Sponges, sharks, jellyfish, seahorses, tuna, squid, octopus, turtles, oysters, whales, abalone, hairtail, white minnows, minnows, redfin fish, tenchfish, sunfish, dolphins, sea lions, crabs, sea snakes, etc.

Blue-green algae, also known as blue-green algae, is a class of large single-celled prokaryotes with a long evolutionary history, negative Gram stain, flagella, chlorophyll a, but no chloroplasts (algae different from eukaryotes), and oxygen-producing photosynthesis.

Sponges are the most primitive multicellular animals, which have lived in the ocean 600 million years ago and have developed to more than 10,000 species, accounting for 1 15 of the marine animal species, and are a huge "family". Except for about 20 species of spongilla, which are freshwater, they are all distributed in the intertidal zone of the sea and the ocean to a depth of 8,500 meters (more than 28,000 feet), and live a sedile life.

Sharks are fish in the ocean. Sharks have been on Earth since 300 million years before the appearance of dinosaurs, and they have been around for more than 500 million years, and they have barely changed their chain for nearly 100 million years. Sharks, known as sharks, sharks, and sand fish in ancient times, are behemoths in the ocean, so they are called "wolves in the sea".
