Reefs
Coral reefs are one of the purple structures that consist mainly of living organisms found in shallow water in which sources of nutrition are not available. As for marine reefs, they are one of the rocky and sandy barriers found under the surface of the sea. They take different shapes and types, and belong to the anemone class. In this The article will talk about its whereabouts and some information about it.
Reef place
Reefs are mainly found in shallow waters, especially in tropical tropical areas in the Dead Sea region. Perhaps the most important thing that distinguishes them is their different shapes, including: coral reefs, which are characterized by their rectangular shape, and coral reefs, which are characterized by their horizontal shape.
Coral proliferation
Corals reproduce according to their species. For example, hermaphrodite species reproduce asexually, while monoecious species reproduce sexually. In most species, sperm and eggs are produced. The fertilization process occurs on the same night every year, producing a larvae that swims until it reaches the top of the sea. It remains there for several weeks, then returns to the bottom of the sea to attach itself to a solid surface, where it later turns into a polyp.
The polyp begins to reproduce asexually, then forms polyps that are similar to it and stick together, eventually forming a large group of corals. When the polyp dies, it leaves behind its exoskeleton, the basis of which is another polyp that builds its own skeleton. Thus, the reefs begin to form new layers of polyp structures. Dead and damaged.

The importance of reefs
- Fish nutrition: Fish eat coral.
- It can be used to treat various bone diseases, due to the hardness and durability of its tissues.
- It preserves the land, thus protecting it from waves that are eroded by storms.
- It is distinguished by its striking and attractive beauty, so millions of people visit it annually to see it, and therefore it has been classified as one of the components of tourism.
Threats threatening reefs
- Building coastal cities in irresponsible ways, as some individuals pour cement on them, thus eliminating them and their death.
- Pollution of sea water, leading to the death of coral reefs.
- Global warming: Global warming is one of the harmful environmental factors for reefs, as it kills and eliminates them.
- Using wrong methods in fishing.
