The existence of coral reefs are a symbol of the unique beauty and richness of the sea. They make up a great deal of the Indo-Pacific islands. Coral reefs have been under severe pressure from human activities for many years. Now, they are being forced to recede from the sea front due to global warming, and this phenomenon is posing dire threats to the lives of marine animals.
Ancient Use Of Corals
In the past, corals were used to provide food by preventing other animals from eating other food. They provided a food source for fish and other sea creatures, because animals would build their nests on top of them. However, human activities have led to the gradual erosion of the coral reefs. Coral reefs provide shelter for sea animals, but now, the animals must seek other places to live.
Coral reefs have animals living within them, but not all the animals are coral reef animals. Most birds, including species of parrots and chickens, are not part of the coral reef ecosystem. Fish also do not belong in coral reefs, but they provide an important part of the food chain. The main animals that are part of coral reef ecosystems are sponges, crabs, lobsters, snails, and small fish such as catfish. Most coral reefs are also home to tropical fish.
Located In Shallow Water
Most coral reefs are located in shallow water. In the case of the Great Barrier Reef, which is considered one of the largest coral reefs in the world, corals can only survive in extremely shallow water. They cannot endure high temperatures and are susceptible to harmful predators.
Some corals and animals are directly dependent on the marine phytoplankton for the production of their food supplies. Marine phytoplankton produces a lot of oxygen and it is the source of food for animals such as lobsters, crabs, snails and small fish. Animals living in coral reefs are protected from direct sunlight, so they rarely see the sun, which is a good thing when it comes to plant life. But they still need to receive enough food to grow. Animals, plants and sometimes even bacteria make use of the sunlight to help them grow.
One of the most important parts of the marine environment found in coral reefs is the coral itself. Most corals are sponges, which are covered with a thin layer of a transparent substance called ichtyonium. This ichtyonium is the part that absorbs the light and uses it as food. Many animals live in the corals, but some animals depend on corals for food like sponges and snails.
Coral reefs also provide a habitat and a home to many animals and plants, which can sometimes make them look a lot like real forests or grassland. There are several animals that live in coral reefs, but they are different from those found in real habitats. These animals come from very different places all over the world, including Australia, Hawaii and some parts of South America. Most animals that live in coral reefs belong to the class of cephalopods, including sponges, snails and clams.
Some corals are home to animals that look more like creatures that are alive in their natural habitat. There are a few animals in the corals that are considered to be true parasites. These animals do not directly benefit from the existence of other organisms, but they help corals by controlling the population of other animals. They catch food, hide away in the corals and wait for their mates to come back to feed. When other animals are interested in eating the corals, they knock over the parasites and stop the corals from getting a new supply of food.
