Coral Reef Types

Good Essays
The book, Coral Reefs, by Simon Rose, presents that categories of coral reefs, what coral reefs are home to, and the dangers that they may face. Coral reefs are made up of coral polyps that attach and multiply to a limestone skeleton called a calicle. Coral reefs are categorized in three ways, which is by their type. 1. Fringed reef, 2. Barrier reef, 3. Atolls. The fringed reef either borderers the shore near a lagoon, or it will be directly attached, next is the barrier reef. The barrier reef, on the other hand, it is more exposed to the ocean; it is separated from the shore by a lagoon. The barrier reef can be very long, and they grow parallel to the coastline. The last type of reef is the atoll reefs. The atoll reefs start off as a fringing …show more content…
The last example is a cay. Cays are low, sandy islands located on the surface of coral reefs. They develop when the material collects in the lagoon or on the reef, which then forms land above sea level. Coral reefs are home to a vague species and types of animals. The types of animals that coral reefs shelter are fish, echinoderms, and mollusks. Fish makes up a huge amount of animals living in coral reefs. Wrasses are a common type of fish in the coral reef. Fish species include: angelfish, butterfly fish, pufferfish, scorpionfish, seahorses, and multiple species of ray. Not only fish, but some sharks species live in or near coral reefs, such as the caribbean shark, blacktip shark, and the white tip shark. The sharks are the only ones that are on top of the food chain; they are the main predator. They mostly feed on fish, eels, and crabs, and can survive six weeks without food. Echinoderms are invertebrates (animals without a backbone), usually with five appendages (a projecting part of an invertebrate), that come out of their bodies. Echinoderms are very common in coral reefs and there are more than 1200 species of sea …show more content…
Octopuses, squid, clams and marine snails are often spotted near coral reefs. These reefs face danger in three different ways. One, they are affected by chemical waste in the ocean, which is disposed from industries, and agriculture. What happened is that industries produce a runoff, and it is disposed in the ocean, which is environmentally unhealthy and it damages a lot of life in the oceans. Not only does industries have a negative effect on coral reefs, but so can boats and ships. These structures and models can rupture and damage the life of coral reefs, and it may take many years for it to recover. As ships and boats move by in a channel, there is a high possibility that they will run through and damage the coral reefs. Changes in their natural environment can affect coral reefs. Heat of the ocean water can affect the coral reefs. If the temperature of the ocean changes too fast, and the coral reefs do not have enough time to adapt, they may lose their zooxanthellae and they may become completely white, and more fragile. Coral reefs have many factors that build up to be a pleasure to the eye, but we have to help protect it and keep

    The gas binds with ions to form carbonic acid which softens the water, ruining the habitat for corals reefs. The acid affects the corals ability to builds its skeleton because their is less calcium ions in the water for it to use. The Great Barrier Reef Marine Park Authority 's stated "From a current pH of 8.2 (alkaline), it is predicted that the ocean’s pH could fall to about 7.8 (still slightly alkaline) by 2100." Slight changes in ph impact coral in a large scale, temperature increase is also inevitable. The symbiotic relationship between algae and coral is at risk, if the temperature is even off by a few degrees, whole ecosystems would collapse.…

    Sharks are one of the top predators in the ocean. With little to no enemies, humans have been over hunting sharks for their fins and then throwing them back out into the ocean. Without their fin sharks would not be able to swim and would slowly sink to the bottom of the ocean and die, waiting for something to either eat them or drown to death. As someone who once enjoyed drinking shark fin soup after finding out what happens to the shark and the life that they have after their fins get cut off I can only feel guilty for enjoying an animal's death. There are many different species of sharks that are out there in the world that is accounted for, and maybe hundreds of sharks that have not yet been discovered yet.…

    Another threat is tidal emersions. Long periods of very low tides leave shallow coral heads which damages reefs. The amount of damage has to do with weather conditions and time of day. If it is daylight, corals are subjected to the most ultraviolet radiation. This can dry out and overheat the coral tissues.…

    Levels of sewage pollution are very high and has caused a variety of sponges, and other species to decline. Releasing sewage into the ecosystems is one of the primary causes of coral reef degradation. Coral reefs ecosystems are extremely sensitive to environmental disturbances. Longer exposure and higher concentrations of oil is killing corals. “Death may not be immediate, but rather take place long after the exposure has ended”(How does an oil spill affect coral reefs, n.d.).…

The genus Protopterus is the only genus affiliated to the family Protopteridae. The lifespan of lungfishes is about 20 years and more especially under favorable conditions. African lungfish are characterized by their outstanding adaptations that enabled them estivate during dry season. The species is also known by their aggressiveness as they can bite when agitated and hence it is advised to club the fish once caught whether to quieten them or bring them to death.…

    Symbiodium possess different types of chlorophyll and carotenoids which provide nutrients and color to corals. There are many causes of coral bleaching not just one direct cause. Because they are so sensitive coral bleaching can be caused by temperature flux and influxes, darkness, introduction to a large amount of CO2, and pathogenic micro-organisms. With so many possible causes of coral collapses it is an easy observe to make that these symbiotic relationships ecologically risky but offer a great reward if maintained for both species. Corals are made out of carbonate ions in particularly calcium carbonate or CaCO3, and with the influx of CO2 coral structures have been degrading over…
