Fauna and flora of Hawaii
The fauna of Hawaii is particularly rich because of the absence of natural predators. There are good number of unusual aquatic animals are the pride of the Hawaiian people. According to recent studies, with the arrival of the first Polynesian (400-800 AC), is calculated to more than 65 varieties of birds endemic to the territory of Hawaii. Of these, it is believed that almost a third are now gone.
As against, the scientists found no traces of reptiles, amphibians, mosquitoes, lice, fleas or cockroaches. It is believed that the Polynesians first arrived on the islands of Hawaii, we did not find a species of endemic mammals: the bat and the monk seal. It is believed that it was by accident that bats are found on Hawaii.
Since very long time, predators were absent altogether, some animals have adapted differently to the environment of Hawaii. We calculated 90% of species occurring in Hawaii as found nowhere else.
Importation of animals in Hawaii
Inspections at ports of entries for Hawaii are very strict order not to import animals unwanted in the Hawaiian territory. Besides the best examples is the program to eradicate the snakes in the area. Indeed, this animal is not of Hawaiian origin and its presence in the Hawaiian territory can break the food chain and caused the decline of a species.
Mammals in Hawaii
Hawaii still has some mammals, living mainly in the hinterlands. Therefore there are wild pigs, horses, sheep and goats brought by early settlers. By against, sometimes we find the monk seal on some isolated beaches of the various islands of Hawaii.
Maui is nevertheless one of the best islands to observe the richness of the Hawaiian fauna. You can see the famous humpback whale and follow in its annual migration.
On the island of Hawaii, there are wild horses in the valley of waipo. The remains of mammals are in the interior.
One can see wild pigs and goats in the valleys and mountains.
Hawaiian monk seal
The Hawaiian monk seal is a direct parent of seal found in the warm waters of the Caribbean and Mediterranean. In the 19th century it was in real danger of extinction in cases of merchants who wanted to sell its skin and oil. Fortunately, laws have ensured that recently a population of monk seals has enabled the species out of danger. In 2004 there were around 1400 monk seals in the waters of Hawaii.
The Hawaiian monk seal is also known by its scientific name Monachus schauinslandi. Its scientific name comes from the first skull was reduced from Laysan Island by Dr H. Schauinsland.
Even if its survival seems assured by rather strict laws, yet it is considered as an endangered species. That is its endemic (unique) which makes this specimen seal, an animal whose conservation is imperative.
The indigenous Hawaiian monk seal named as "Ilio holo-i-ka-uaua-" Hawaiian word meaning "dog that runs in rough water." He gave the name of monk seal because of its round head covered with short hairs, giving it the appearance of a medieval monk. It is believed that the "Monk Seal" comes perhaps also his later solo compared to usual seals that live in groups.
The Hawaiian monk seal is considered the most primitive animal of the family Phocidae. It is believed that this sub-species would be separated from the seals there are about maybe 15 million years.
In adulthood, monk seals have a coat becoming gray-brown after heavy rainfall. By against, young people have a silver color.
At birth the seal has a black fur short black hair. A number of Hawaiian monk seals have outstanding bites shark attacks. The female seals may also be severely marked by their encounter with males, which can be particularly brutal. Males can reach weights of 300 to 400 pounds with a size of 7 feet, while females can reach 8 feet with a weight of 400-600 pounds .. The life expectancy of monk seals is about 30 years.
The Hawaiian monk seal is in danger of extinction in the region of Hawaii and is part of the Act on the endangered species. It is illegal to kill monk seals that you can still see in Kauai, Niihau, and other islands.
When the monk seal dives, its heart activity is reduced to 1 / 10 and even 1 / 15 of normal. The circulatory flow is slowed to a minimum. The brain and heart continue to receive oxygenated blood in reserve in the posterior vena cava, while the other viscera and members less susceptible to anoxémie, are provided more or less anaerobic. It might be feared, as a result of a long stagnation, the blood freezes, but all the fishermen who have killed seals have been observed: in these animals, coagulation occurs late.
Moreover when the monk seal performs a dive, they consume energy, it usually comes from the combustion of sugars, with formation of carbon dioxide and water, but when oxygen is lacking, this energy is unique in another way. We now know that the degradation of carbohydrates through two stages, at the end of each, there is a release of energy. During the first form, without the need of oxygen, lactic acid, which is also in the second phase and thus emerges from the carbon dioxide and steam water. When the monk seal is immersion only occurs the first part of the reaction, the oxygen is provided when the animal goes back to the surface to breathe. In fact, this same process in mammals and humans when they submit their bodies to a sustained exercise. The downturn that followed a high activity is nothing but the manifestation of the need for oxygen, and the aches are due to the accumulation of lactic acid in muscles. As against, it should be noted that the monk seals resist much more effort than humans because they can tolerate large amounts of lactic acid to carbon dioxide.
Birds of Hawaii
Estimates and observations of scientists in Hawaii, we believe that it is in Hawaii or more species of birds have disappeared on the planet over the past 200 years. On nearly 70 different species that could count two centuries ago, around 25 are missing and nearly 30 are in real danger. Emphasize the Hawaiian crow and Alala.

It is believed that the torture seas ocean travel for more than 200 million years. It is only recently that the species is now threatened with extinction. Moreover, many programs, both in Hawaii and in several islands in the Pacific, working for the conservation of this ancient animal. In fact, of the seven turtle species, 6 are in danger.
According to Chinese mythology, the turtle is the representative of wisdom.
Marine mammals of Hawaii
For centuries human beings thought the world was flat like a giant satellite dish and a very large river snaked its perimeter. For the old and even for the peoples of the Middle Ages, this belt of water was hostile and populated monsters. It was not until the fifteenth century that the vastness of the oceans was collected. The great discoverers as Columbus, Magellan, Mercator, Tasman and Cook will discover with time that the extent of water is much greater than the land.

During the evolution of the seabed and the creation of the Hawaiian Islands by volcanoes that ocean currents have brought fish species in the region. As concerns the species of the region, there are different types and morays eels. In general, these animals are not harmful, except in rare occasions when they feel attacked.
The parrot fish is without doubt one of the most colorful fish of coral reefs. This is a live fish in the rocks and coral reefs of Hawaii and can be up to 4o cm.
