Ecosystems: Coral Reefs

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,

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. Nearly half or I’d rather say all of the worlds coral reefs, are in the tropics. How beautiful does that sound? Coral reefs are also important to us (humans). The value of coral reefs has been estimated at 30 billion U.S. dollars and as much as 172 billion dollars each year, providing food, protection of shorelines, and jobs based on tourism and …show more content…
This reef is made up of over 2,900 individual reef and 900 islands. Now that’s huge! Its stretches over 2600 kilometers off the northeast coast of Australia. There are 10 main coral reefs that are very large in size besides the reef I already mentioned. I already spoke of the biggest one which is the Great Barrier Reef (Australia). There’s the Red Sea Coral Reef (Red Sea near Israel, Egypt and Djibouti), New Caledonia Barrier Reef (Pacific ocean near New Caledonia, The Mesoamerican Barrier Reef (Atlantic Ocean near Mexico, Belize, Guatemala and Honduras), Florida Reef (Atlantic Ocean and Gulf of Mexico near Florida), Andros Coral Reef (Bahamas), Saya Del Maha (Indian Ocean), Great Changos bank (The Maldives), and the Reed Bank (South China Sea, claimed by the

    However, about 40 percent of the 16 percent of the reefs in the world that were seriously damaged in 1998, due to coral bleaching from El Niño, are either recovering well or have fully recovered. Despite that, since 1998 coral bleaching has become even more severe. Every region has now experienced severe coral bleaching, causing much bleach-induced mortality (see figure 3) (Shah). Zooanthellae, which are what give coral their beautiful colors, live on corals and provide them with 95 percent of their energy for growth, reproduction, and feeding, making them key in coral’s survival. With climate change, this causes the water to warm up, making corals go into stress, which causes the zooxanthellae to desert the coral, which in turn causes the bleached appearance (Cesar, et al.).…

    The GBR’s coral rarely grow lower than 40 meters below sea level since sunlight passes through shallow and clear waters. It has no real soil, being a marine coral ecosystem, but loose carbonate mud covers 135,000 square miles of land. Its biotic factors are animals & plants. It is highly diverse, with 1,500 fish species, hundreds of types of corals, 500 algae species, and many sharks, rays, marine mammals, crustaceans, and echinoderms. Animals like the dugong, butterfly fish, jellyfish, green sea turtle, tiger shark, blue-ringed octopus, krill, cuttlefish, and Crown of Thorns starfish, although of different species, sizes, and niches, all adapt for one of two common goals: to eat or to keep from being eaten.…

    “We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity” (Edward Owen Wilson, 2006). The Great Barrier Reef (GBR) was inscribed on the World Heritage List in 1981 and stretches for more than 2300 kilometres along the northeast coast of Australia, including an area of about 347 800 square kilometres of seabed. It is the largest coral reef ecosystem in the world with 2500 coral reefs and is home to more than 1500 species of fish and 5000 species of mollusc. Approximately 215 species of birds are found on its islands and cays. Despite the GBR being given World Heritage status the health of the GBR has declined to date.…

    “Runoff carries nutrients sediments, and pollution from land-based sources and deposits them directly onto our reefs.(http://wwf.panda.org/).” Too many nutrients create algal growth creating a decrease in oxygen levels leading to the condition, Eutrophication. Erosion by construction, inland or along coasts, mining, logging and farming increases sediment in rivers. This then ends up in the ocean where it smothers corals by trapping them from the light which is needed to survive. Sedimentation limits the light ability to the corals inhibiting their ability to feed and reproduce.…

    A) What is a coral reef? Coral reefs are underwater ecosystems that are formed by many small animals called polyps, which through their ability to excrete calcium form the limestone skeleton that they live on. As coral reefs grow they can take on three structures fringing, barrier or atoll. The Reef located along the Queensland coastline is called the Great Barrier Reef as it is separated from the shoreline by a section of deep open water.…

    Along the coast of Queensland, Australia, corals spread over 1000 miles to form the iconic Great Barrier Reef that is visible from space. However, the greatest marine species diversity can be found in Indonesia because it lies at the cross between the Indian and Pacific Ocean. There, corals thrive by building a mutualistic relationship with algae, which grow in the tissue of the polyps. Seahorses find refuge in corals by blending in to protect themselves from predators. The venomous banded sea snakes display an interesting behavior.…

    I have noticed some changes the past couple of vacations I have spent there, including changes in these beautiful coral reefs. It seems like every year I go, the coral reefs seem less and less bright and seem to lack the one thing I thought they were known for-life. Signing up for this course made me hope that I could learn why these amazing creatures were diminishing before my own eyes, and hopefully I could learn what to do to help. Throughout my oceanography class, I have learned an abundance of information about the ocean, but the one lecture that stood out was the one that taught me that coral reefs are amazing, mesmerizing creatures, and is so essential to the environment around us. I have also learned that coral reefs are in a huge amount of danger, while bringing the fish that feed off of them into danger also.…

    Biodiversity of Coral Reefs By: Ganesh Balaji Ecology is a macro-scale science that encompasses all biological life. However, in order to fully understand the depth of ecology, and its significance in relation to life on earth, one must study the biodiversity of the species living in this planet. Although the history of modern human civilizations has largely ignored the importance and complexity of biodiversity, understanding the many layers of biodiversity will provide us with richer knowledge on how we can improve our own lives. Biodiversity acts as the principle foundation of ecology, as it serves as the link between the many ecological systems presently constructed on Earth.…
