features of the environment. An Ocean habitat is a place where communities of organisms live. The three main ocean habitats of the ocean are the open water‚ the soft sandy to muddy bottom and the hard shore. Examples of ocean habitats are the coral reefs‚ the estuaries and the abyssal zone. Habitats can be classified in a number of ways in order to compare them at different times‚ across different geographic areas‚ and in terms of different life history strategies. Habitats are as varied as the animals

Coral Reef Bleaching Coral reef bleaching‚ which is the whitening of diverse invertebrate taxa. The cause of the whitening is “from the loss of symbiotic zooxanthellae and/or a reduction in photosynthetic pigment concentrations in zooxanthellae residing within the gastrodermal tissues of host animals.” (P.W.Glynn) The reason why coral reef bleaching is such a concern is because the “consequences of bleaching large numbers of reef-building scleractinian corals and hydrocorals.”(P.W.Glynn)

failing fisheries when worldwide the fisheries spent $124 billion to catch the fish but‚ got $70 billion out of it so the governments covered up the shortfalls. Coral reefs are on the verge of collapse because of overfishing. Also the coral reefs have decreased from about 28 percent to 13.8 percent. About 19‚300 square miles of coral reef has been lost due to overfishing. See humans and animals are being affected by commercial fishing and overfishing.Humans could find another food source other than fish

The Great Barrier Reef‚ located off the coast of Queensland‚ Australia‚ is the “world’s largest coral reef ecosystem”‚ according to the Great Barrier Reef Marine Park Authority (GBRMPA). It is home to about 2‚900 individual coral reefs‚ but unfortunately‚ as of 1990 and continuing until today‚ this number is rapidly declining. This active downturn is primarily due to the catastrophic coral bleaching event being held in their ecosystem. Coral reefs have an optimal water temperature of (20-27 celsius)

The islands of Ko Samui‚ Ko Phangan and Ko Tao enclose the bay from its eastern side 2) Bandon Bay is under threat because of … Sedimentation due to deforestation Near-shore coral reef systems are experiencing increased sediment supply due to conversion of forests to other land uses. Counteracting increased sediment loads requires an understanding of the relationship between forest cover and sediment supply. All of this eroded sediment

Another example is coral reefs which serve as a home to thousands of fish in the ocean such as the parrot fish. Parrot fish eat coral reefs and if they don’t have a predator to control their population size it could be detrimental to the coral reefs. The parrot fish would become overpopulated and all these fish would eat away the coral reefs. (TEDxYouth). The ocean’s ecosystems would collapse without coral reefs. Many species are at risk of extinction without coral reefs; even humans would be impacted

Hawksbill turtles like this because the reefs have sponges they like to feed on. Hawksbills are omnivorous and will also eat mollusks‚ marine algae‚ crustaceans‚ sea urchins‚ fish‚ and jellyfish. Their hard shells protect them from many predators‚ but they still fall prey to large fish‚ sharks

regardless of its legality. Three areas to examine are; the effect on the coral reefs or ocean floors‚ the effect on the marine life‚ and ways to prevent further damage. Indonesian fishermen have been destroying the off shore reefs for decades and is the largest area of concern. “Damage from bombs and other disruptions‚ like sedimentation‚ cyanide fishing‚ and coral mining‚ has severely degraded 70 percent of the nation ’s reefs and left only six percent in excellent condition” (Ryan‚ 2001).

Input from the freshwater streams provides nutrients‚ sediment and other materials into the bay. Pollutants are added to the bay from terrestrial runoff and land development. Kane’ohe Bay is also an area known to be a popular location for take of desirable aquarium fishes.

MURO- AMI Muro-Ami Fishing‚ otherwise known as reef-hunting‚ is one of the cruelest‚ most cataclysmic forms of illegal fishing that destroys the coral reefs and exploits children. This practice consequently destroys corals which take whole lifetimes to form and causes the deaths of some of these unfortunate children. For casualties ensuing from these practices (either a kid gets caught in the big net that they use‚ or the bomb explodes before the children assigned to handle the bomb could leave
