The copy of Chelonia mydas heavier than there has been weighed 395 kg.

It is one of the most studied species of sea turtle, and much of what is known about sea turtles generally comes from studies of the green turtle. The ecology of Chelonia mydas changes drastically through every stage of your life. For example, the newborn turtles are carnivorous organisms, pelagic nekton of the mini-open ocean.

The government will cancel and deny temporary visas of people who are not traveling yet, and new visa applications will not be processed. Holders of permanent visas who have not yet come to Australia must undergo a quarantine of 21 days before departure.

Checks at airports have identified more than 800 people who entered Australia from West Africa and who may have been in areas affected by Ebola, but none required hospital visits upon his arrival.

Australia has donated 18 million Australian dollars (US $ 16 million) to combat the disease, but it will not ship until staff is satisfied that any Australian who became infected receives appropriate treatment.

Oceania's Flora and Fauna


In Oceania there is a great diversity of species of animals and plants, the variety of territories enables this great natural wealth. It has tropical, subtropical, particular ecosystems on each island due to the influence of the sea and tundra ecosystems to high mountain. 

This continent has many unique species of the world, first on the island of Papua it has great diversity and have recently found new species never before seen. This island has very particular ecosystem and is unique in having evolved separately from inland areas, so there are species that are only found on this island. 

Something similar happens with the islands of New Zealand and Australia. Having been influenced by some species must be unique species in these two places among which the diversity of marsupials. Another example of this is the island of Tasmania, off the coast of Australia, in which they have animals like the famous Tasmanian devil or boodye, a nocturnal marsupial. 

It was the arrival of people determinant of extinction of ancient megafauna living in Australia, like the giant kangaroo. At present have species like the red kangaroo, the platypus, the spotted quoll or broom tail possum and the famous koala. 
The flora will have a large number of species, some of them native to this region and have been carried around the world. Eucalyptus trees are often found in some forests of Victoria. The jungle of Tasmania offers an incredible wealth that is only found in this part of the world, many of its plants are extinct in the rest of the world long ago
