White Sharks are More Aggressive in Australia



The alarming increase in great white shark attacks off the coast of Australia has led local authorities to consider reviewing the status of protection of this great predator. “The five fatal attacks (ten months) are unprecedented and raises an alarm,” said Minister of Fisheries Western Australia, Norman Moore, in a statement to the media.

The latest victim was the 24-year-old Australian, Ben Linden, who was surfing last Saturday when a great white of five meters long emerged, near Wedge Island, about 180 kilometers north of Perth. Coastguard services are still searching for the remains of the young surfer, while the pursuit of the shark was suspended about 24 hours after the attack.

Few days earlier, the fishermen in the area had spotted the a shark. Moore called for “new measures” regarding the status of protection of the white shark, after saying that its population has increased almost two decades after being declared vulnerable. The shark attacks in Australia have risen more than in other parts of the world.

In time, authorities in Western Australia have ordered to close the beaches near the area of the attack. The representative of the Wildlife Society of Western Australia, Janita Enevoldsen, said in remarks that the exclusion of the great white shark from the list of protected species is not the right solution to these attacks.

Marin Garwood, Sydney Aquarium expert, questioned the existence of a direct relationship between humans and an increase shark attack. He said that there are no reliable statistics. According to Garwood, the latest attacks do highlight the increased presence of humans in new marine areas and noted that in the last decade, the practice of adventure sports such as surfing, has become popular.

The Ministry of Environment of Australia estimated that there were fewer than 10,000 copies of a white shark in 1990, which was incorporated in the list of species protected, although it is impossible to make an accurate assessment of the population. The first known fatal attack of a great white shark in the ocean country dates from 1791 and since then. there have been 689 cases, of which 200 have been fatal, according to Conservation Society of Australia.

The great white, which can grow to 5.5 meters long, became the world’s famous murderer in the 70’s. This aquatic animal usually feeds on fish and other species such as rays, marine mammals, shellfish and sea birds.

Australia Will Create Largest Network of Marine Reserves


The Australian Government will create the largest network of marine reserves in the world and limit the exploitation of oil and fishing in sensitive areas to help protect the oceans.

The network will increase the number of reservations from 27 to 60 and will cover about 3.1 million square kilometers, more than a third of the ocean surrounding the country-continent.

“It is time that the world take a turn in the protection of our oceans,” announced the Minister of Environment , Tony Burke, noting that “Australia will lead the course” in favor of a more responsible management of marine and resources.

The minister stressed that many Pacific Island countries are concerned about the impact of mining activities and other resources in the oceans, so far not only responds to the need to “protect the environment” but is linked also to food security.

Under this plan, which must be subjected to a final consultation process before implementation in Australia, will expand the protection of animals such as whales, turtles and other endangered species including the gray nurse shark and dugong (sea mammal relative of the manatee).

Also, it aims to limit the oil and gas exploration, an activity that represents the engine of the Australian economy, and increase the protection of the reefs in the Coral Sea, off the coast of Queensland, which is home to the green turtles.

The initiative, announced a few days after the Rio Earth Summit +20, opens the possibility that the fishing industry in compensation claims around a $99.7 million.

According to the Executive in Canberra, the measure will affect only one percent of commercial fishing in the country.

But while there are “many interests at stake,” Australia has a “responsibility” as a country to lead global efforts to protect the oceans, said Burke.

The announcement sent alarm bells ringing in the fishing industry, which warned that the increase of protected areas will mean a greater volume of fish imported to the detriment of local industry.

For its part, the representative of the Australian Conservation Foundation, Chris Smyth, welcomed the measure, although he emphasized that the protected area will not be as extensive as he would have liked.

“There are many interests involved, the industry of oil and gas, commercial fishermen and amateurs as well as environmental groups,” he told ABC .

The new marine reserves announced by the Minister included the Perth Canyon, southwest of the country, “which is larger than the Grand Canyon,” although “the jewel in the crown” is the Coral Sea, northeast Australia .

The Coral Sea area and the adjacent Great Barrier Reef marine reserve representing the world’s largest, said the minister.

The director of the Australian Marine Conservation Society, Darren Kindleysides, said that in the Coral Sea can not be carried out activities such as oil and gas exploration, mining on the seabed and trawling.

The Coral Sea “has a long chain of coral atolls that are important for various species of fish and sharks,” said Kindleysides, who recalled that marine reserves help protect wildlife and biodiversity.

The creation of marine reserves is the highest level of protection and excludes extractive activities, although the movement of ships, tourism and recreational activities such as scuba diving are permitted.

In 2010, the tenth Conference of the Parties to the Convention on Biological Diversity, held in Nagoya (Japan) agreed that 10 percent of the world’s seas should be protected in 2020.

Australian Tree Frog (Litoria splendida)


Did you know?

That the males of Litoria splendida produce a substance that is released into the water to attract female species?

The Australian Tree Frog is a large tree frog that is 10 cm in length. It has dark olive color schemes to bright green on its back, with yellow or white spots scattered. The inner surfaces of the forelegs, hind legs and groin are bright orange yellow. The belly is white and granular. A large gland completely covers the top of the head. The skin of the back is smooth. They have three fingers that are slightly webbed. The color of the species may vary depending on the region where they are.

The Litoria splendida breeds in the early rainy season with the onset of monsoon rains (December and January). A female lays eggs on average about 1,000, floating in groups and forming a single layer on the water surface. The larvae takes from 1 to 4 months to develop, depending on when the eggs were laid.
