3. Dolphins: Dolphins are aquatic mammals closely related to whales and porpoises, which evolved in the Miocene about 10 million years ago, and lived widely in shallow seas near the continental shelf, and occasionally found in freshwater. Feeds mainly on fish and mollusks.

A variety of dolphins constitute the dolphin family, which is the most diverse family of marine mammals, with a total of 37 species in 17 genera in the world, and 18 species in 13 genera in China. Dolphins have a friendly-looking appearance and a playful personality, and have always been very popular in human culture.

4. Whales: Whales are divided into two categories, one is baleen whales and the other is toothed whales. Whales belong to the phylum Chordates, subphylum vertebrates, mammals, and eumatria, which contain about 98 species of viviparous mammals living in oceans and rivers.

There are more than 30 species in China's waters. All but a few species of whales live in freshwater, and all but a few inhabit the ocean.

5. Starfish: Starfish are echinoderms of the phylum Echinoderma. 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 wrist 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.

Crabs, jellyfish, squid, octopus, dolphins, squid, etc.

1. Crab: It belongs to molluscs, decapods, and is a crustacean whose body is protected by a hard shell and breathes by gills.

2. Jellyfish: Jellyfish are plankton in the aquatic environment and belong to the class of spiny filamentos.

3. Squid: It is an animal of the order Cephalopoda Squid of the mollusc phylum Cephalopoda. There are small sacs of pigment in it, which change color and size with changes in mood.

4. Octopus: Octopus is the general name of 252 species of marine mollusks in 26 genera of the octopus family. The body is ovate or oval, muscular, the mantle cavity has a narrow opening, and the body surface is generally without water holes.

5. Dolphins: Dolphins are aquatic mammals that live widely in shallow seas near the continental shelf, and are occasionally found in freshwater.

6. Squid: It is an animal of the mollusc phylum Cephalopoda Sheath subclass Ten Wristed Tube Squid Eye-opening Suborder. The body is conical, pale, with light brown spots, the head is large, there are 10 tentacles in front, and the fleshy fin at the end of the tail is triangular.

The small animals on the bottom of the sea are: sand silkworms, Hawaii.

Seahorses, squid.

Sea butterflies, sea snails, airbag jellyfish, flying squid, lobsters, sea butterflies, starfish, conchs, sea urchins, basket snake tails, crabs, nudibranchs, seahorses, deep-sea sandworms, etc.

Other animals on the ocean floor.

Sharks are fish in the ocean that have lived for more than 500 million years. They have barely changed in nearly 100 million years.

The seahorse is a small marine animal with a length of about 5 to 30 cm. Seahorses are slow, but they can catch copepods that are agile and good at stealth.

Dolphin. It is widely found in the world's oceans, inland seas and near river estuaries, and some species also appear in inland rivers. Dolphins usually prefer to live in groups and prey on fish and squid.

The underwater animals include turtles, dolphins, sharks, etc. The ocean occupies a very large area on the surface of the earth, the ocean occupies 70% of the earth's area, and the ocean is also the place we want to explore the most, from the surface of the sea to the bottom of the sea, there are animals, and there may be animals that have not been discovered.

Distribution of benthic fauna

Light Zone: From the surface of the sea to 200 meters underwater, light can penetrate this range, and animals such as seabirds, shells, jellyfish, etc.

Low light area: 200 meters to 1000 meters underwater, the sea water in this location is relatively cold, and the animals include zooplankton, shrimp, fish, etc.

Deep sea area: 1000 meters below the water, the sun basically does not shine on this position, it is pitch black, and few animals survive.
