Coral polyps | The most famous coral reefs in the Red Sea | Diving in Egypt

A species of coral, especially individuals called polyps, can live alone in the waters of the Red Sea, but nevertheless they are closely related to, or even closely related to, large and amazingly diverse communities of limestone. With those coral reefs that are mainly involved in its construction and formation.

What are coral polyps?

In fact, coral reef death, or the threat of coral dying and extinction, is one of the biggest challenges and threats that coral reef systems can face in the Red Sea.
Also, due to the recent marked increase in the temperature of the water surrounding marine organisms in the Red Sea, none of those polyps found in reef structures can handle this temperature difference.
As changes in temperature eventually lead to a significant change in its color and eventually lead to its death as a result of exposure to those temperature differences for long periods.

But which coral polyps face this threat?

In fact, polyps are an organism that is close in shape and composition to jelly fish.
These polyps in the reef structure act as a large network that eventually forms the large, magnificent reef skeleton that you can see today in the Red Sea.
In general, these polyps are basically a relatively large group made up of small sea stomachs, and they always like to take their food from the oceans in all places and directions, and then use that food to build and store the building blocks of the main component of corals.
It is originally a small mouth and can sometimes be hidden. This mouth after tracing to the stomach, this substance in its visible form with the naked eye somewhat resembles a sac because it is often surrounded by tentacles that are believed to be stinging.
Also, this stomach is the only place where any kind of calcium and carbonate ions can occur, which the polyps get from the waters of the Red Sea and eventually turn into a large coral skeleton made of calcium carbonate.

This skeleton, which is ultimately made of the same material as limestone, is fully and fully responsible for building a successful home
These polyps should sit in it completely all day.

But these polyps can regress at night and move out of this house until you succeed in completing the night feedings.
Also, in order to successfully generate the energy that these polyps need to eventually form the skeleton, these polyps can be fed using multiple methods.
The area around the mouths of these polyps is often covered with a large group of stinging cells called marine world nematocysts.
In addition, when any type of zooplankton or small aquatic creatures pass near it, the tentacles around the mouth will sting them, eventually paralyzing the zooplankton and succeeding in pushing them into the mouth of this hungry tumor.
Polyps, colonies and corals

In fact, these polyps are originally small and compact, as well as soft in texture and body, and are closely related to both sea anemones and jellyfish.
There is also a skeleton at the base of these polyps, which is characterized by its hardness and protectiveness, which succeeds in protecting it from the limestone called calicle, and this skeleton, of course, is what constitutes the structure of the corals.
Polyps can also begin to exercise corals when they succeed in attaching a polyp of them to a rock permanently located on the sea floor, and then split or split by budding to eventually form as many as thousands of clones of it.
Also, these polyps or polyps can connect to each other, and this ultimately leads to the successful formation of that huge colony that acts on the sea floor as a single organism.
Also, as these colonies grow in age and size over hundreds and thousands of long years, they can manage to join other nearby colonies that transform into a massive structure of colorful corals.
Some of these corals began to survive on the planet and have continued to grow for nearly 50 million years.

color and bleaching

  • Did you know that polyps of coral, or what is known as polypeptides, are basically animals that are transparent in color?
  • Where those coral reefs that you see in the seas and oceans get all their wonderful wild colors from billions of species and sizes of algae known as zooxanthellae, which are characterized by being colorful, as these polyps are distinguished by hosting them.
  • Also, when these polyps are exposed to any form of stress that they are exposed to due to things and environmental factors such as a significant and noticeable change in temperature or the occurrence of pollution, those polyps and coral reefs will fly out of their borders.
  • This sudden exit and expulsion can eventually cause coral bleaching, which can eventually kill the entire colony if it is not treated and relieved of pressure.


  • This polyp lives in any of the tropical waters around the world, including the waters of the Red Sea in Egypt.
  • They like to live very close to the surface of the water.
  • The sun’s rays can also reach the places of these polyps and provide them with energy.
  • Therefore, those coral reefs in the Red Sea can get all kinds of nutrients they need to be able to survive from all the by-products that result from the successful completion of the process of photosynthesis in polyps and algae.
  • These polyps also possess a large number of venomous tentacles that are spiky that can come out of them, especially at night.
  • These polyps come out at night for the primary purpose of being able to grab those zooplankton and even any other kind of small fish.

threats to survival

  • In fact, as it is known, all types and shapes of coral reefs are teeming with life from different locations, and they can nevertheless cover less than one percent of the entire ocean floor.
  • But despite the tiny area it covers, it can support nearly 25 percent of any known species of marine life.
  • Despite all those tasks and the active role it plays, the threats it faces to ultimately maintain its existence and health in the ocean are many.
  • Where marine scientists and researchers estimate that any kind of human factors, such as water pollution, and both global warming and the resulting sedimentation on the ocean floor, can eventually threaten large and wide areas of coral reefs found in waters around the world.
