What are corals?

Bangladeshi coral is the wealth of our country. “Coral” is a foreign word whose meaning is [Probal]. Coral [Probal] is a type of animal. The island of Saint Martin in Bangladesh called the coral [Probal] island. When coral [Probal] is mention, most people first think about clean, Tropical Ocean and fish land. Indeed, rocky, shallow-water corals-such as coral reefs-have only one type of coral. There is also soft coral in dark cold water and coral in deep water.

Almost all corals are colonial organisms. This means that they are composed of hundreds to hundreds of thousands of individual animals, called polyps (Barnes, R.D., 1987; Lalli and Parsons, 1995). Each polyp has a stomach that opens at only one end. This opening, called the mouth, is surrounded by a circle of tentacles. The polyp uses these tentacles for defense, to capture small animals for food, and to clear away debris. Food enters the stomach through the mouth. After the food is consumed, waste products are expelled through the same opening.

Corals are related to sea anemones. Although some corals can catch small fish and plankton using stinging cells on their tentacles, most corals obtain the majority of their energy and nutrients from photosynthetic unicellular din flagellates in the genus Symbiodinium that live within their tissues. These are commonly known as zooxanthellae. Such corals require sunlight and grow in clear, shallow water, typically at depths less than 60 meters (200 ft). Corals are major contributors to the physical structure of the coral reefs that develop in tropical and subtropical waters.

Is Coral an animal or a plant?

Yes, coral is an animal. And unlike plants, corals do not make their own food. Corals are in fact animals. The branch or mound that we often call “a coral” is actually made up of thousands of tiny animals called polyps. A coral polyp is an invertebrate that can be no bigger than a pinhead to up to a foot in diameter.


What is coral in color?

Coral (color) Coral is a reddish or pinkish shade of orange. The color is named after the sea animal also called corals. The first written use of coral as a color name in English was in 1513.

What are coral reefs?

Coral reefs are large underwater structures composed of the skeletons of coral, which are marine invertebrate animals. Each individual coral is referred to as a polyp. New coral polyps live on the calcium carbonate exoskeletons of their ancestors, adding their own exoskeleton to the existing coral structure. The coral species that build coral reefs are known as hermatypic or “hard” corals because they extract calcium carbonate from seawater to create a hard, durable exoskeleton that protects their soft, sac-like bodies.

Functions of Coral Reefs:

Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet. They: protect coastlines from the damaging effects of wave action and tropical storms. Provide habitats and shelter for many marine organisms. Coral reefs are part of a larger ecosystem that also includes mangroves and sea grass beds. Mangroves are salt tolerant trees with submerged roots that provide nursery and breeding grounds for marine life, that then migrate to the reef. Mangroves also trap and produce nutrients for food, stabilize the shoreline, protect the coastal zone from storms, and help filter land based pollutants from runoff. Sea grasses are flowering marine plants that are a key primary producer in the food web. They provide food and habitat for turtles, seahorses, manatees, fish and foraging sea life such as urchins and sea cucumbers, and are also a nursery for many juvenile species of sea animals. Sea grass beds are like fields that sit in shallow waters off the beach, filtering sediments out of the water, releasing oxygen and stabilizing the bottom.

What is a coral reef used for?

Coral ecosystems are a source of food for millions; protect coastlines from storms and erosion; provide habitat, spawning and nursery grounds for economically important fish species; provide jobs and income to local economies from fishing, recreation, and tourism; are a source of new medicines, and are hotspots of. [HOTSPOTS: Such were the extremes of temperature that hot spots in the building were still smoking more than 24 hours after the fire broke out.]

How do corals eat?

While most of a corals diet is obtained from zooxanthellae, they can also ‘fish’ for food too. During feeding a coral polyp will extend its tentacles out from its body and wave them in the water current where they encounter small fish, plankton or other food particles. The surface of each tentacle has thousands of stinging cells called endoblasts, and when small prey floats or swims past, the tentacles fire these stinging cells, stunning or killing the prey before passing it to the mouth.


What coral reefs do for us?

Coral reefs provide a buffer, protecting our coasts from waves, storms, and floods. Corals form barriers to protect the shoreline from waves and storms. The coral reef structure buffers shorelines against waves, storms, and floods, helping to prevent loss of life, property damage, and erosion.

Why is the coral reef so bright and colorful?

The colors found in colorful corals are mostly due to three things – photosynthetic pigments, fluorescent proteins and non-fluorescent chromo proteins. Colorful corals contain symbiotic algae, or zooxanthellae, which are brownish or green because of the photosynthetic pigment called “chlorophyll”.


Scientists say they have found a way to recover the coral which have been damaged. After a successful test of coral production, Australian scientists are claiming this. The researchers say that they are first raising eggs of these corals, they are able to keep them growing in the lover. Then they are replacing them with a part of Great Barrier Rift. After a few months there, they saw the coral being growing very well. A group of scientists from South Cross Crossing of Australia conducted the study. They said that it is possible to repair the damaged coral reefs in other parts of the ocean using this process. Due to the increase in the activities of these people and sea temperatures, these corals are dying or their lives are in danger. Earlier, environmentalists were talking about protecting these corals in a different way. And that is to break some parts of the healthy corals and plant it somewhere else. It has come that the coral will survive even in Stefan. I was talking with Bangladesh Natural Science Professor Saidur Rahman Chowdhury of Chittagong University.

To begin with, I want to know that these corals are scattered everywhere in the sea?

  • No, it is actually very small in the ocean and in very few environments, the coral is born. The stream is actually a very small animal. It is an animal in the remittance period of the Jellyfish tribe and these animals are very small, we all know as polytypic. They attract many alike, attracting algae among them, as a large number of poly-collective call informants and them or with them as syndicate again. This combination of these algae and minerals and animals and plants is made up of a coral and requires very specific conditions for these corals to grow. First of all, the temperature is an environment. Cold water is not coral. Coral is our equation and Gravity is not more than 40 [40] meters in our region. 40 [40] is less than meters, because the coral is a part of the Gower [LG] or the algae has its need for sunlight again.

When we go to Cox’s Bazar, we see that these white colors, like small stones, like limestone, are seen in different shops in Dhaka, it is also a kind of coral.

– Yes, that is the dead coral and some were collected from the St. Martin Island region. You can hear some of the things some people have imported from other countries.

Why are these coral reefs being destroyed under the sea?

  • There are several important reasons. There is a climate change between them. But there are other reasons. This is usually due to hydroelectricity. This is what we know as coral bleaching. So if we increase the temperature of the sea water and increase acidity, we call it Ocean Acidification. When ocean acidification occurs and the temperature increases, the seaweed that was with him as an emigrant, abandoned the algae. As a result, the color of the coral is turned white. He dies – we call it bleaching. There are also some important reasons:

  • In some countries of the world, BESTSTUSTING is phishing. Fenning as a coral corpuscular poison or dynamics. The coral is destroyed by physical or poisonous action. Coral is destroyed by water pollution. As well as the oil pollution, if several endoscopy polices are found in the coral region, and then coral is damaged. Another reason is the tourism. Destroy trustworthy tourism.

Mr.Chowdhury – We are at the place but the coral is under the sea. So, what is the relation between the earth, the future, the environment, and the coral reefs necessary for this coral destruction?

  • One number is Kotla coastline. Protecting the solar line of Bangladesh protects the rocky coastline from the rocky structure, stream and waves of waves. Coral is the Marine Fish and Marine Animals that are ours. They have a very important nursery ground and heavyintens here, lots of species of fish and other marine creatures come in the coral reefs, and hatch eggs and grow. Most of the ocean from coral reefs is in neutrino supply. The whole world is covered by less than one percent of the entire sea coral reef. But it has been said that 1 in 4 animals of the sea, about 25 percent of the Organisms dwelling coral reefs. So, we realize that on the coral rehabilitation of the coral wall and the reclamation of the coral reefs, the food cycle in our oceans, and the supply of our fish all this – Coral Reef.
