What are the main types of marine animals?

There are dozens of phyla of marine animals, which can be divided into two categories: marine invertebrates and marine vertebrates, or three categories: marine invertebrates, marine protochordates and marine vertebrates.

1. Jiawan porpoise: Jiawan porpoise inhabits a narrow range and is accustomed to warm water areas.

2. Dugong: Dugong has the title of "mermaid", which is very similar to manatee, and is currently mainly distributed in tropical sea areas. Dugongs are very slow to move and have high water quality requirements.

3. Bluefin tuna: Bluefin tuna is mainly distributed in the Pacific Ocean and the Atlantic Ocean, and they inhabit different depths and like to move in groups.

4. Blue whale: 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.

5. Hawksbill turtles: Hawksbill turtles are relatively large in size, with an average of more than meters, and scales are also distributed on the forehead.

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.

1. Dolphin: an aquatic mammal with a spindle-shaped body. 2. Sperm whale:

The head is huge, with a body length of up to 18 meters. 3. Starfish: It is in the shape of a five-star and has a bright color.

4. Sea rabbits: There are a pair of antennae similar to rabbit ears, the shape is small and cute, and the color is mostly white. 5. Flounder:

The body is flat and has a pointed head.

1. Dolphins

Dolphins are the fastest moving mammals in the water, have a well-developed sonar system, and dolphins are good at jumping and diving, with nostrils on the head, which makes it easy for dolphins to jump out of the water to breathe, dolphins are small to medium size cetaceans, their body length is to meters, and their weight is 30-14,000 kg.

2. Sperm whale:

Sperm whale is a large marine animal, its head is huge, weighing more than 50 tons, and the head of the sperm whale accounts for one-third of the body, mainly feeding on squid, sperm whale is a social creature, widely distributed in the world's non-frozen seas, will carry out north-south migration every year, swimming speed can reach more than ten nautical miles per hour.

3. Starfish

Starfish is a representative species of echinoderms, its body is flattened, the shape is similar to a five-pointed star, and the starfish is active when the mouth is facing downward, the back is upward, its bones are connected by connective tissue, the body can be bent, widely distributed in the sandy seabed and coral reefs, and there are about 1,600 species of starfish.

4. Sea rabbits

The sea nudibranch, also known as the sea slug, is a shallow sea shellfish, with two pairs of antennae similar to rabbit ears on the head, its shell has degenerated into an inner shell, and there is a thin layer of shell skin on the back, the color is white, and the sea hair is a hermaphroditic creature, and there is an egg sperm groove between the two reproductive pores of the male and female.

5. Flounder:

Flounder, also known as flounder, is a fish that grows on the bottom of the sea, its body shape is flattened, asymmetrical, two eyes are distributed on the same side of the head, the eyeless side has no pigment, and adult flounder will permanently lie on one side of the seabed.

There are four main types of marine life: marine animals, marine plants, microorganisms and viruses.

Marine life, a biological term, 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 animals are a general term for heterotrophic organisms in the ocean, and there are many phyla, which can be divided into marine invertebrates, marine protochordates and marine vertebrates. The main phyla of marine invertebrates: protozoa, sponges, coelenterates, flattened animals, neomorphs, nematozoa, annelids, molluscs, arthropods.

Brachiopods, whiskers, etc.

What are the marine animals.

Marine protochordates are a group of animals that are intermediate between marine invertebrates and marine vertebrates, all of which are seafood, including caudal chordates such as sea squirts. Chordates, such as the Wenchang fish.

Marine vertebrates include marine fish and reptiles.

Birds, mammals.

Among them, marine fishes are roundmouthed, cartilaginous fishes and bony fishes. Marine reptiles include leatherback turtles, turtles, sea snakes, etc.

Marine birds such as albatrosses.

Shearwaters, petrels, boobies, ** birds and puffins, etc.

1. There are dozens of categories of marine animals, which can be divided into three categories: marine invertebrates, marine protochordates and marine vertebrates.

2. Marine invertebrates, accounting for the vast majority of marine animals, are the most diverse, mainly protozoa, sponges, coelenterates, flattened animals, neomorphs, nematoids, annelids, molluscs, arthropods, brachiopods, hairy jaws, whiskers, echinoderms and hemichordates.

3. Marine protochordates, animals between vertebrates and invertebrates, including caudal chordates and cephalic chordates.

4. Marine vertebrates, including fish, reptiles, birds and mammals that depend on the ocean.

That's all there is to know about the classification of marine animals.
