What plants and animals are in the sea?

Corals, various marine plants (seaweed, kelp, etc.), marine plankton, molluscs.

starfish, jellyfish, sea cucumbers), various shellfish, fish, mammals.

dolphins, whales) and more.

The animals in the sea are seahorses, sharks, jellyfish, tuna, crabs, squid.

Octopuses, turtles, oysters, whales.

Abalone, hairtail, white minnow, pressed minnow, redfin fish, tench, dolphin, sea lions.

Wait a minute; There are mainly algae plants in the sea, such as cyanobacteria, red algae, brown algae, green algae, coral, kelp, sponge, spirulina, rotaphylla, etc.

Most of the animals that live in the sea are aquatic animals that have not lived out of the water during the evolution of the species, or aquatic animals that have been transformed from terrestrial animals to aquatic animals, and they can perform aerobic respiration in the water, such as whales, which breathe with their lungs.

The plants in the sea are mainly algae, and sometimes there are others, such as algae plants reproduction rate is very fast, so in some sea areas, the wild growth of algae will cause eutrophication of seawater, affecting the life of animals in the sea, and also affecting the growth of nearby plants.

These animals and plants are interdependent, for example, after the death of an animal, the carcass decomposes and becomes an aquatic plant.

Many plants are animal food, so no one lacks them.

There are a lot of creatures in the sea, but this thing makes me wonder if it's a plant or an animal.

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, pressed minnows, redfin fish, tench hookfish, 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". With the exception of about 20 species of the genus Spongilla, which are freshwater, they are all distributed in the intertidal zone of the ocean to a depth of 8,500 meters (more than 28,000 feet), and live sedentically.

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 in 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".

The animals in the sea include seahorses, sharks, jellyfish, tuna, crabs, squid, octopus, turtles, oysters, whales, abalone, hairtail, whitefish, minnows, redfin fish, tenchfish, dolphins, sea lions, etc.

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

The animals and plants in the sea are also interdependent. After the death of an animal, the carcass decomposes to become the nutrition of plants, and many plants are the food of animals. It is the harmony of animals and plants in the sea that makes up the perfect ocean.

Marine life: Marine life refers to the living species in the ocean, including marine animals, marine plants, microorganisms and viruses. According to the distribution of marine organisms in China's waters, they can be roughly divided into two categories: marine organisms in waters and marine organisms in tidal flats.

Among the marine life in the water, fish, cephalopods (such as the cuttlefish, also called cuttlefish) and shrimp and crabs are the most important marine organisms. Among them, fish have the largest variety and quantity, and constitute the main body of marine life in the waters.

Animals in the sea include seahorses, sharks, jellyfish, tuna, crabs, squid, octopuses, turtles, oysters, whales, abalones, hairtails, whitefish, minnows, redfin fish, tenchfish, dolphins, and sea lions.

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 sea creatures belong to 5 kingdoms 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%.

Marine animals are a general term for heterotrophic organisms in the ocean. The ocean is an important life support system, and marine animals are an important part of the biological world.

In the sea, the number of animals concerned. There should be thousands of kinds, and there should be no way to list them all here, you can search for them on the Internet.
