Why do different species of corals choose different time periods to release ?

Mainly because of the temperature, the temperature is different when released.

Because each type of coral has its own suitable time to release.

Different species have different times of release. It is related to the temperature of the seawater.

This is related to the temperature of the seawater, and the "release time" of different species is also different.

Because the temperature of the sea water is different at the time of day, it will cause different species.

The main reason is that the temperature of the seawater is different, and the release time of different species is also different.

The temperature of the sea is different, so choose a different time.

Coral reefs are one of the most biodiverse marine areas on the planet, with hundreds, if not thousands, of interdependent species in between. This biodiversity is due to the fact that coral reefs provide food, shelter, mates and reproduction for these marine creatures. Coral reefs can also serve as breeding grounds for large fish and allow them to grow safely, and when they are large enough, they can swim into the depths of the ocean.

Because at what time is the most suitable for corals.

The temperature of the seawater is different, and the time of release is also different.

Corals are lower animals. It belongs to the coelenterate group and has only two germ layers, the inner and outer layers. It has only one mouth, food enters through the mouth, and indigestible residues are expelled through the mouth.

There are many tentacles around the mouth, which can catch food and also make water flow into the mouth and body cavity through vibration, digesting small creatures in the water.

Because coral is a calcareous and skeleton, it is composed of a combination of polyps and zooxanthellae, and its body structure is very simple, and it is an invertebrate lower animal.

The shape of the coral is very much like a tree branch, much like a plant, but it actually has only one mouth, and the debris will be discharged from the food when it enters from the inside, and there are many tentacles around it, which can be used to catch food.

Corals, which have tentacles, use their tentacles to hunt and walk, and their other methods are to float freely or sessile to the bottom habitat

Because coral itself is an animal [do not spray].

Of course not! Coral coral coral clusters are divided into two major groups: hexacorals and octacorals, and only the stony corals (also known as hexacorals) in the hexacorals subclass have the potential to form coral reefs (hence their also called reef-building corals).

other corals, some inhabit the deep sea; Although some are in shallow seas, they grow slowly, and the rate of bone accumulation after death is not as fast as the speed at which the tide washes away; Some mavericks coexist with certain active organisms, and are not fixed on hard rocks; ......

The only species of the stony coral order are fast-growing (mainly symbiotic with algae), and at the same time, they live in large groups, and the calcareous shell can accumulate smoothly after the death of the orange, which forms the necessary conditions for the formation of coral reefs.

To be clear, not all stony corals can successfully create coral reefs, and in order to form coral reefs, they must be located in shallow tropical seas, have a suitable pH value, and have no natural predators that deliberately prey on corals.

The majority of polyps are hermaphroditic, and whether they are hermaphroditic or not, polyps can expand their populations through both sexual and asexual reproduction.

Sexual reproduction can open up new territories, and fertilized eggs can travel far away by sea, but the fertilization rate is less than 1 in a million. Asexual reproduction is the main way coral colonies grow, and the polyps form interconnected colonies to ensure that the coral colonies continue to expand.

Coral is protected by law in our country, and it is illegal to poach, buy and sell without permission, and damage it, so let's protect corals, care for the environment, and build a better marine world together.

When subjected to some environmental stress, the chromoproteins and fluorescent proteins in the coral will be expressed into red, blue, purple, pink and even a variety of colors with fluorescent effects to protect the coral, and the most precious red coral is a first-class protected animal at the same level as the giant panda.

The importance of corals:

Corals are important not only for the ocean, but also for our own human health and the global economy. Corals look like rocks, but they are actually made up of tiny organisms called polyps.

They hunt by filtration at night and then secrete minerals to form their shells. There is a seaweed that lives in the ocean and they provide food for polyps through photosynthesis, and polyps and this seaweed are symbiotic organisms, one provides shelter and the other provides food.

Coral reefs are the source of life in the oceans, the basis of the vast food chain and the basis of the human food web. Coral reef-dwelling fish provide high-quality protein for millions of people around the world.

You may not realize that coral reefs not only provide humans with seafood, but there are many more important things – the creatures in coral reefs secrete chemicals that are not found on land. These chemical ingredients can be used as pharmaceuticals or to make some other supplements.

Coral reefs are important barriers to the coastline, preventing the erosion of near-shore areas by marine storms. It is also a good place for tourism and diving sports, and they bring tourism benefits to the local people. However, our current approach to harvesting seafood is destroying coral reefs and destroying the possibility of future coral exploitation. Our annual catch is something that the ocean can't recover naturally.

Sometimes, we also use destructive methods of fishing, such as using poisons or explosives to blow up the fish, which disrupts the ecological balance and is difficult to recover over a long period of time, which leads to the replacement of one species by another, and the decline of fish leads to algae overblooms, which eventually suffocates the entire coral.

In addition, there are many human actions that harm coral reefs. Industrial and agricultural wastewater and construction work near the coastline can completely bury coral reefs, causing algal blooms in the spring.

Warming oceans are also causing coral bleaching, with colorful corals and seaweeds turning pale in color, which further damages coral reefs. Since the ocean absorbs a lot of carbon dioxide, the sea water becomes acidic, which makes it difficult for polyps to grow.

Corals move, corals themselves are animals, some socks will use their tentacles to hunt, some will move slowly, and the polyps will automatically fix on the calcareous bones of the ancestors of the coral at the stage of preparing the white larvae, and the coral is the shell secreted by the polyp. The body of a coral is composed of two germ layers, the outer cell layer is called ectoderm, the cell layer is called endoderm, and between the inner and outer germ layers there is a mesocolloid layer of cell structure. <
