1. Blue stripe upside down.

Adult blue-striped upside hangers often swim happily in the waters off Mexico. The blue-striped upside-down belongs to the Spiny Tail, Caribbean.

There are a lot of blue veins hanging upside down in the domain, especially in the coral reef area. As they age, their color changes from bright yellow to dark blue.

Gray or purple.

2. Clownfish.

The alternating stripes on the body and fins of the imperial angelfish attract the eye of many nature lovers. They prefer to live alone, or in pairs, and prefer sponges and sea squirts.

The lilac head of this rare flower-capped jellyfish is seductive, but also dangerous, and it can be very painful to sting when stung by it. People in Brazil, Argentina.

And found in southern Japan, this species has antennae that can unhook coils and be used to catch small fish and other food.

Fish, crustaceans (shrimp, crabs, etc.), molluscs (mussels, etc.), amphibians (frogs, toads, etc.), reptiles (water snakes, turtles, etc.), plankton (paramecium, etc.).

There are turtles, dolphins, starfish, walruses, seahorses, squid, squid, blue whales, killer whales, blue-ringed octopuses, humpback whales, sperm whales, and other animals in the sea.

1.Sea turtles: belong to the order of turtles, turtles, and turtles.

It is widely distributed in the Atlantic, Pacific and Indian oceans. Chinese sea turtles are found in the coastal waters of the Beibu Gulf from Shandong in the north to the south of the Beibu Gulf. It can be more than 1 meter long and has a lifespan of about 150 years.

There is a pair of forehead scales on the top of the head.

2.Starfish: It is the most representative group of echinoderms with structural physiology.

The body is flattened, mostly symmetrical with five radiations, and the demarcation between the body disc and the wrist is not obvious. When living, the mouth faces down, and the mouth faces up. The ventral side of the belly has a step groove, and the groove protrudes from the tube foot.

The plates of the endoskeleton are connected by connective tissue and are flexible and flexible.

3.Dolphins: with morphological traits typical of toothed cetaceans:

spindle-shaped body; a single crescent-shaped breathing hole; skull intussusception, postmaxillary extension overlapping the frontal bone; left-sided asymmetry of the cranial parietal; conical or nail-shaped teeth, etc. The most obvious variations are related to feeding organs such as beaks, upper and lower jaws, and teeth.

4.Walrus: An animal of the genus Walrus in the family Walrusidae. As the name suggests, the elephant in the sea has a large body, wrinkled skin, sparse bristles, small eyes, and poor eyesight. It has two long teeth.

5.Seahorse: It is a general term for several small fish species of the family Hydrosauridae of the order Thornfish, and is a small marine animal with a length of 5-30 cm.

It is named because the head is bent and the body is close to a right angle, the head is in the shape of a horse's head and forms an angle with the body, the snout is long and tube-shaped, the mouth is small, and the dorsal fin is one, all of which are composed of fin bars. The eyes can move independently.

6.Squid: also known as soft fish, spear squid, is an animal of the mollusc phylum Cephalopoda Sheath subclass Decabrae Cyclophyta Squid Eye-opening suborder.

The body is conical, pale, with light brown spots, a large head, 10 tentacles in front, and a triangular fleshy fin at the end of the tail, often swimming in groups in the ocean at a depth of about 20 meters.

7.Blue whale: is a marine mammal that belongs to the suborder Baleen Whales.

There are four subspecies. The blue whale is believed to be the largest animal known to have ever survived on Earth, reaching up to 33 meters long and weighing up to 181 tons. The blue whale has a slender body and a blue-gray back, although it can sometimes be lighter in the water.

The animals in the sea include seahorses, sharks, jellyfish, tuna, crabs, squid, octopus, turtles, oysters, whales, abalone, hairtail, white minnows, pressed minnows, redfin fish, tench hookfish, dolphins, sea lions, sunfish, sea snakes, etc.;

There are plants in the sea such as cyanobacteria, red algae, brown algae, green algae, coral, kelp, sponge, spirulina, rotula, etc.

After decades of investigation and research by marine science and technology workers, 20,278 species of marine organisms have been recorded in the waters under the jurisdiction of China. These large marine organisms belong to 5 biota and 44 phyla. Among them, the animal kingdom has the largest number of species (12,794 species) and the prokaryotic kingdom has the least (229 species).

China's marine biological species account for about 10% of the total number of marine biological species in the world, and the number accounts for 50%.

The species of marine animals such as turtles, whales, starfish, jellyfish, seahorses, seals and so on are very complex, and almost all the phylum and class of terrestrial animals have representative species in the ocean, and marine animals can be divided into zooplankton, swimming animals and benthic animals from the living habits.

1. Marine invertebrates

The number of species and phyla is the most numerous, accounting for the vast majority of marine animals. The main phyla are: protozoa (protozoa), sponge (porifera), coelenterate (coelenterata), flattened (platyhelminthes), nemertinea, nemathelminthes, annelida, mollusca, arthropods (arthropoda) , brachiopods (brachio-poda), hairy-jawed animals (chaetognatha), whiskered brachiopods (pogonopho-ra), echinoderms (echinodermata) and hemichordates (hemichor-data), etc.

Among them, brachiopods, hairy-jawed animals, whiskered wrists, echinoderms, and hemichordates are endemic phylum in the ocean.

2. Marine protochords

Protochordates are a class of animals that fall somewhere between marine invertebrates and marine vertebrates. Protochordates are all seafood, including urochordata, such as sea squirts (ascidia); cephalochordata, such as branchiostoma. In the past, it belonged to the protochord group, but now most scholars advocate putting it in invertebrates.

3. Marine vertebrates

These include marine fish, reptiles, birds, and mammals. Among them, marine fish are cyclostomata, chondrichthyes and osteichthyes. Marine reptiles include leatherback turtles (dermochelidae), such as leatherback turtles (dermochelys); Sea turtles (cheloniidae), such as loggerhead sea turtles (Carettta) and hawksbill turtles (Eretmochelys) Marine animals.

The animals that are present in the sea are: marine mammals, marine reptiles, vertebrates, marine arthropods, marine molluscs, marine coelenterates.

1. Marine mammals.

There are 39 species of sea beasts in China. Such as: all kinds of cetaceans, dolphins, seals, sea lions, dugongs, etc.

1) Seals: The body is not large, only meters long, the largest weighs 150 kilograms, and the female is slightly smaller, weighing about 120 kilograms.

2) Sharks: Known as the "overlords of the sea", sharks are found in all oceans of the world, and most of the sharks are beneficial and harmless to humans, and only more than 30 species of sharks will attack humans and ships for no reason.

2. Marine reptiles.

Reptiles are ectotherms whose bodies are covered with scales and reproduce on land.

3. Marine fish.

Fishes are one of the lowest groups of vertebrates. In China's waters, 3023 species of marine fish have been recorded, including 237 species of cartilaginous fish and 2786 species of bony fish, accounting for about 1 7 of all marine species in China.

4. The ocean is arthropod.

At present, a total of 4362 species of arthropods have been recorded in the China Sea, accounting for about 1 5 of all marine biological species in the China Debate Lubi National SeaSuch as horseshoe crabs, shrimps, crabs, etc.

5. Marine mollusks.

A total of 2557 species of molluscs have been recorded in the China Sea, accounting for about 1 8 of all marine species in the China SeaSuch as stone turtles, mussels, pearl oysters, scallops with celery, oysters, clams, squid, octopus, etc.

6. Marine coelenterates.

Coelenteric sihu animals are also called cnidarians because of their unique cnidarians. At present, a total of 1010 species of marine coelenterates have been recorded in the China Sea, which belong to the three classes of the phylum Coelenterates.

Some of the animals in the sea are small fish. All kinds of rain. Due to the water machine wild ducks. Wait a minute.
