There are many uses for coral, but is coral a creature or a plant?

Corals are living organisms, and corals belong to the phylum Coelenterates and are made up of polyps.

Plants, according to relevant understanding, coral is a plant, and it has a lot of uses, and it is common in people's lives.

It's a living thing. According to the research of some scientists, it is conclusively determined to be a living organism and can also perform some breathing.

It is a living organism, it has its own life, it lives in the ocean, it has a very strong ability to survive, and its own role is also very large.

Animals, of course.

Corals are animals. Coral belongs to the class of polyps of the phylum Coelenterate, which is the largest class in the phylum Coelenterate, with more than 7,000 species, all of which are seafood.

Coral is a living thing, a type of animal. Corals are groups of polyps or fossils formed by their skeletons, which belong to the category of animals. Although they are animals, they can play some similar roles to plants, such as absorbing some of the carbon dioxide and mitigating the greenhouse effect, similar to plants on land.

Although corals grow into trees, they are not plants but animals, because they are actually formed gradually by polyps, and when the coral coral dies, the coral will not grow, so corals belong to animals.

Animal, this is an invertebrate, it is a sea creature, so it is not a plant, it is a type of animal.

I think coral should be living things, because coral is alive, not a plant.

This is a creature that usually lives in the ocean, and then it is also a relatively low-level coelenterate type of animal.

It belongs to living things. And it's also alive, and the place where it lives in general is in the ocean. It doesn't look like an animal.

It is a living thing, a shell secreted by a polyp.

Corals are coelenterates called polyps, which are only 1 centimeter in size, and tens of thousands of polyps gather together to call corals.

It's a living thing, it's moving, it's growing, it's going to live for decades, it's an animal.

Beautiful corals are made up of countless tiny, tiny polyps, and the dead coral coral leaves behind their skeletons, where new coral coral continues to grow and reproduce, and over the years, twig-like corals are formed. So corals are animals.

In fact, corals are living coelenterates, corals belong to the class of coelenterates and are the largest class in the phylum Coelenterates, with more than 7,000 species, all of which are seafood.

The class of polyps is further divided into the subclass Octoctocoral and the Subclass Hexacoral. According to the bone texture and polyp size, corals are generally divided into several types, such as large polyp stony corals, small polyp stony corals, soft corals and sea anemones. It can be fixed to the seafloor or on the surface of rocks, and its tubular outer wall secretes limestone, which is used to form an exoskeleton that surrounds a soft body.

These bones grow branches like trees, creating coral colonies. The corals that you can usually see are the bones left behind by the coral polyps after they die.

Social corals live mainly in shallow sea waters with a depth of 0 30m. The most typical example is the Great Barrier Reef in Australia. Their skeletons are joined together, and the intestinal lumen is also joined together by the small intestinal system.

They have many mouths, but they share a common stomach. They are suitable for temperatures of 22-30 degrees Celsius, and it is more difficult to survive below 18 degrees Celsius.

Polyps are further divided into two categories: "reef-building" and "non-reef-building".

Reef-building corals. The polyps that build reef-building corals absorb calcium and carbonate ions from seawater to synthesize calcium carbonate, which is the "skeleton" that supports its shape, except that its "bones" grow outside the body - the corals picked up by the sea are full of small holes. The polyp spends its entire life in the hole, and after its death, the body decomposes into a reef and becomes the foundation of a new polyp, and the cycle repeats, after tens of thousands of years of accumulation, it can grow into a coral reef on the bottom of the sea.

Coral reef islands are formed when the earth's geology changes and the submarine reef rises above the sea.

Non-reef-building corals.

Non-reef-building corals also have calcium carbonate skeletons, but they are so small that when the polyps die, the bones separate and dissipate, leaving nothing behind.

Some of the coral resembles a mill, some resemble a fan, and some resemble a human brain.

Some of the corals resemble flowers, and some resemble branched antlers, but they are beautiful.

Some of the corals resemble ice prisms in cold caves, and some resemble the slender horns of the bifurcated deer.

Some of the coral resembles antlers, some resemble fans, some resemble chrysanthemums, and some resemble branches.

Some of the coral resemble antlers, some resemble monsters, and some resemble small animals.

Some of the coral resembles the antlers of a deer, and some resemble spears.

Some of the corals resemble blooming flowers, some resemble branching antlers, and some resemble icicles in a cold cave.

There are many kinds of coral, some like trees, some like flowers, some like stones, and so on.

Some of the beautiful coral bushes are like a beautiful landscape painting, some are like small hills, endless, and some are like a strange stone.

Some of the coral bushes are like stars in the sky, some are cute little hands, and some are like hesitant green grass.

Some of the beautiful coral bushes resemble the horns of a sika deer, some resemble clear blue gemstones, and some resemble small saplings without budding.

1. Coral is an animal. Corals are groups of polyps or fossilized bones. The polyp is a marine cylindrical coelenterate, food enters through the mouth, food residue is excreted from the mouth, it feeds on the small plankton in the ocean, can absorb calcium and carbon dioxide in the seawater during the growth process, and then secrete limestone, which becomes its own survival shell.

2. A general term for many types of organisms in the corals. The body is cylindrical, with eight or more tentacles, and the tentacles have mouths. Mostly gregarious, combined into a group, it is a marine cylindrical coelenterate that feeds on the small plankton of the ocean, with food entering through the mouth and food residues excreted from the mouth.

As they grow, polyps absorb calcium and carbon dioxide from seawater, and then secrete limestone, which becomes their own shell. Polyps living in colonies, their skeletons are connected together, and the intestinal lumen is also connected through the small intestinal system, so these colonies of polyps have many mouths, but they share a common stomach. There are about 500 species of polyps capable of building coral reefs.
