Coral Reefs
A coral (disambiguation) reef is a community of living organisms. It is made up of plants, fish, and plenty other creatures. When I think of coral reefs I think of neon colors, and beautiful colorful dancing plants of the sea. Coral reefs are a submerged structure made up of many different corals, or small marine invertebrates. Coral reefs are some of the diverse ecosystems in the world. Twenty-five percent of all marine life is actually home to it. Coral reefs have said to be the foundation for many marine species. They are also a crucial support for human life. Coral reefs have been around for millions of years. About 0.1% of the ocean floor is covered by coral reefs. Coral reefs are the homes of many species including crabs,

Sponges, crabs, shrimps, sea worms, starfish, sea turtles, and many other species of sea are thought to be like the rainforest of the ocean. I see them as the magical beauty of the ocean. Believe it or not each coral reef stands for something, and is not just a “plant” or “animal” living in the ocean. Coral reefs are made up of tiny animals that called “polyps” that stay fixed in one place and are the main structure of a reef. Polyps have a hard outer skeleton made of calcium (similar to a snails shell). Polyp is connected by living tissue that forms a community. Coral reefs may vary in size, type, and location around the world but are very sensitive to water properties like temperature, and chemical composition. The top layer is of a coral reef contains living polyp. When new layers of the coral reef are built, the polyps then the leave the lower layers. Each polyp has a ring of tentacles shaped like a cup around a central opening. The tentacles have stinging cells, called nematocysts, which allow the coral polyp to capture small organisms that swim too close.

Food (fish and shellfish) for people living along the coastlines. Coral reefs has also been a source of medication as well. Some of our anti-cancer drugs, and pain killers come from reefs. Reefs help in the carbon cycle, and is also a good sign of ocean water quality. Healthy reefs equalizes healthy water. There are a few things that can also damage and destroy our precious reefs. Fertilizer since it creates condition that make algae increase, CO2 which makes the water acidic. Acid makes it much harder for coral to make their shells. Too much of greenhouse gas emissions make the water warmer. Corals cannot live in water that is warmer or colder than 26-27 degrees Celsius. Sunscreen, pollution from sewage, and herbicides used in home gardens can easily wash into oceans and poison our corals as well. Last but not least fishing methods, like cyanide or blast fishing can harm and kill corals. There are spots in the ocean where there is little to no oxygen called the dead zone. Plants and fish cannot live in water with no oxygen. There is about 400 dead zones in the world, and they seem to be growing in size. The largest dead zone happens to be the Baltic
