Hawaii's Coral Reefs: An enlivened sweetheart
Hiding under the oceans, it can be difficult to ignore the importance and beauties of Hawaii's coral cliffs, but without the coral cliffs Hawaii would be a different place. Coral is not only home to a wealth of flora and fauna, but is also the source of many of Hawaii's breathtaking beaches' whitish sands, helping to produce the ripples of renowned windsurf break spots.
The coral reef also protects the coast from waves and degradation. Chalk is coral? The majority of the coral structure we call consists of several hundred or thousand small creatures, the so-called adenoids, which are related to an anemone and marmalade. It has a smooth, bag-like, transparent structure with a mouth encircled by piercing 10tacles, the nematocyst or nidae.
With the help of saltwater bicarbonates and carbonate ion, the octopus forms a hardened, shell-shaped limestonous frame to help preserve its sensitive organism. Will coral be a vegetable or an organism? From a technical point of view, coral is regarded as an organism because, unlike herbs, it does not produce its own nourishment. Instead, coral use their Nemato cysts to bring zoo plankton and even small pelagic species out of the sea at noon.
Coral, however, has a symmetrical relation to seaweed, which is essential for the marine life and marine wellbeing. Microscopical seaweed named Zooxanthellen (pronounced zo-UH-zan-thuh-lay) lives inside the coral polyps, where they are well sheltered and use the metabolism wastes of the coral for the photosynthetic process. Photosynthetic organics help to growth coral and build coral structure.
Seaweed also gives coral its bright colour and generates air. More than 500 types of seaweed are found in Hawaii's coral coves. Usually coral can be found in semitropical or tropic environments, as they are essential for life. Because zooxanthell light needs solar light to provide nourishment through photo synthesis, coral lives in clear seawater nearer to the sea level so that the sun's radiation can penetrate the seaweed.
Though coral adenoids, like many fungal coral, are known to inhabit large reef-forming comonies. The coral reef begins when coral algae adhere to underwater cliffs or other harsh surface at the edges of an island or continent. It is divided into several thousand interconnected and colonic cells that function as a unique entity.
When single copyps are dying, they are leaving their skeletons to which another copyp can adhere. During this lifecycle, which lasts for millennia, the settlements extend and join together with other settlements to create one. At annual growing at only 0.3 to 2 centimetres for solid coral and up to 10 centimetres per year for branched coral, it can take up to 10,000 years for a coral wall to develop from a group of spawn.
When the coral changes over the course of the years, coral becomes one of three main structures: hem, barriers or islets. The most frequent fringe lesions evolve near the coast, forming a boundary along the coast and the neighbouring islets and often extend back to the sands. The coral avocetlls begin as a fringe around a volcano isle.
Once the entire archipelago has sunk below the sea floor for several hundred thousand years, a round or elongated coral cliff forms with an open bay, the Tole. Accessible coral cliffs also encircle coastlines, but they are divided from the shore by a lake of open, often shallow depth. According to their dimensions, barriere coral corals and avocets can completely develop between 100,000 and 30,000,000 years.
The Hawaii Islands stretch more than 1200 nautical mile ( "2000 km") across the Pacific from the Isle of Hawaii in the south-east to the Kure Atoll in the north-west and make up at least 80 per cent of all coral and waterbodies in the Americas and are one of the few places where all three types of reef can be found.
Hawaii's major isles are encircled by fringe coral cliffs, while off the shores of Oahu and Kauai you can see barriere coral cliffs and pristine plains in parts of the northwestern part of Hawaii. One of the most remote archipelagoes in the hemisphere, about a fourth of Hawaii's coral and marine life, the coral and marine life, plants and invertebrates that live in Hawaii's coral riffs are found nowhere else in the game.
Varying shallows are suited for different species of coral and thatch. The flat coral can grow from the shoreline to a 30 foot deep flat dive, as they can both resist stronger waves. Fingering corals and branched staghorn corals like quieter seas and are happy with the lower lights in the middle 30 to 60 foot area.
At a depth of 60 to 150 ft, dark corals and flat corals require less sunshine and can live through the nutrient-rich current. In place of the species populating the flat and middle part of the coral canals, shark and stingrays enter the depth. The old Hawaiians relied on coral for most of their proteins and used coral in culture and religion.
Recognizing the importance of coral cliffs, they even talk about the coral pole being the first living being of the seas in the Cumpo. The coral riffs occupy less than one per cent of the seabed, but provide about 25 per cent of all seafood. In spite of the importance of the coral riff, researchers believe that contamination, climate change and sediment could destroy 30 per cent of the world' s preexisting coral cliffs over the next 30 years.
Man-made pressures such as urbanisation, over-fishing and the invasion of invertebrate fish are a particular threat to Hawaii's coves. As you kayak, snorkel and enjoy Hawaii's beautiful sandy beach and other marine entertainment, please help us preserve our delicate coral-ribbon eco-system. Avoid touching, standing or walking on corals while boating or snorkelling.
Stinging or going on corals can crush and annihilate the adenoids, which took many years to heal. Do not use coral to give you a thrust and slide your kayak canoe. Smashing, damage or taking living corals or stones with an object is against the law. Don't eat the music.
Run-off with deposits and chemical effluents is the biggest issue for reefs around the major islands of Hawaii. Suffocates coral so that it cannot photosynthetize and starve. Not only coral, but all sea dwellers are damaged by chemical substances. Only take the pelagic you will be eating with you when you go angling.
Become an educated user when purchasing corals or freshwater aquariums for your home or when purchasing freshwater trout for supper. Over-fishing is one of the greatest threat to the marine ecosystems. It is important for us to share our understanding of Hawaii's fragile coral cliffs, so we teach all our kayaker and snorkeller how to treat Maui's marine environment so that we can all continue to experience its beauties for many years to come.
