1. ❓ What Is a Coral Reef?
When you write about coral reefs, you should have a clear understanding of what is a coral reef ecosystem, and what is a coral. We all saw corals on photos, videos or even live. But what exactly are corals? Are they plants or animals?
Let’s find out!
Corals neither are plants, nor a quaint stone, but living marine polyps that have a unique limestone skeleton structure growing about 15 mm every year. Corals are the lower coelenterate multicellular creatures in the world’s oceans.
Imagine a solid lime cylinder, surrounded from the inside and outside by a soft tissue of cells. In its center is the “mouth” of the coral and then it turns into the abdominal cavity. The coral feeds on plankton, capturing small marine organisms with its tentacles around the mouth, which have mucus that paralyzes the prey.
Corals in their structure are very different. Some corals have a solid skeleton (which is called madrepores), some don’t have it, and some have mixed type of skeleton, like tubular coral.
There are both solitary and colonial corals, which together form a complete barrier, shore reefs or atolls. Old corals die, and new living corals grow on top of them.
Corals, like plants, take energy from light, water and carbon dioxide. This happens because of the unicellular algae that live in their tissues. In the daytime the coral functions like a plant, and at night it lives the life of an animal. Another coral reef features are the abilities to glow when the coral gets under ultraviolet rays or illuminated by blue light.
