A frog with fangs, a blind snake and a snub-nosed dolphin are among the more than 1,000 new species recently found on the incredible Melanesian island of New Guinea, according to WWF.

A frog with fangs, a blind snake and a round-headed dolphin are among more than 1,000 new species recently found on the incredible Melanesian island of New Guinea, environment group WWF said.

Scientists made the astounding discoveries, which also included a river shark and dozens of butterflies, on New Guinea at a rate of two a week from 1998 to 2008, WWF said in a new report on the island's natural habitat.

"This report shows that New Guinea's forests and rivers are among the richest and most biodiverse in the world," said WWF's Western Melanesia programme representative, Neil Stronach.

New Guinea, divided between Indonesia in the west and Papua New Guinea to the east, has one of the world's least spoilt and most stunning ecosystems.

Its rainforests are the third biggest in the world after the Amazon and the Congo, and, while the island covers just 0.5 per cent of the Earth's landmass, it contains up to eight percent of the world's species, according to WWF.

One of the most notable finds documented in the WWF report was a round-headed and snub-finned dolphin

A frog with fangs, a blind snake and a snub-nosed dolphin are among the more than 1,000 new species recently found on the incredible Melanesian island of New Guinea, according to WWF.

What was previously known about New Guinea's biodiversity was already breathtaking, such as the world's biggest butterfly -- with a 30-centimetre (12-inch) wingspan -- and giant rats that can grow up to a metre long.

Scientists believe that one square kilometre (247 acres) of the island's lowland rainforest may contain as many as 150 , according to WWF.

The 1,060 species confirmed by scientists as new discoveries between 1998 and 2008 are believed to have only scratched the surface of New Guinea's dazzling ecosystems.

"Such is the extent of New Guinea's biodiversity that new discoveries are commonplace even today," WWF said in its report, titled "Final Frontier: Newly Discovered Species of New Guinea".

One of the most notable finds documented in the WWF report was a round-headed and snub-finned dolphin, which swims in protected, shallow coastal waters near rivers and creek mouths.

Discovered in 2005 in Papua New Guinea, it was the first new dolphin species recorded anywhere in the world in three decades, and is now known to also exist in Australia, WWF said.

Another of the 12 mammals found over the decade was an anteater named in honour of British naturalist Sir David Attenborough, Sir David's Long-beaked Echinda or, scientifically, Zaglossus attenboroughi.

One of the 134 frogs discovered was dubbed Litoria sauroni because its striking red and black spotted eyes reminded scientists of the evil character Sauron in the "Lord of the Rings" movies.

Another new frog was notable because of its tiny size -- just one centimetre in length, while one had vampire-like fangs.

Nine snail , some so colourful as to be almost unrecognisable from the backyard-garden-type variety, were among the 580 new invertebrates discovered.

One of the snails was bright yellow, while another was green and yellow.

Among the other new invertebrates was a brightly coloured apricot crayfish, part of the family of creatures called "yabbies" in Australia and some other parts of the world, which was nine to 12 centimetres long

New fish totalled 71, with a kaleidoscope of colours, including one in the coral reefs of Milne Bay in Papua New Guinea that thrilled scientists with its dazzling blue hue.

WWF said the most extraordinary freshwater discovery was a 2.5-metre-long river shark found in that has since also been located in northern Australia.

Of the 43 reptiles discovered, one could claim to be the most innocuous snake in the world -- it was just 12-14 centimetres long, had scales over its eyes so that it could not see, could not bite and had no venom.

But WWF said the excitement of all the had been tempered by the fact that, like in the and Borneo rainforests, human actions were destroying New Guinea's at an "alarming rate".

Some of the growing threats it listed were illegal and unsustainable logging, forest conversion for palm oil plantations, mining, road construction and unsustainable fishing.

"These environmental threats are exacerbated by global climate change which is increasing the number of fires within forests and savannas, erosion, and seawater incursion into coastal habitats," WWF said.

What remnants of any natural wilderness there are will be confined to areas of the planet deemed unprofitable to exploitation by humans - but even these will be subject to pressures such as poaching as the rare plants and animals become a sort after commodity.

Do you really think that the societies which worship your fake creator(never mind the kind), are the one that will save the world?
You can clearly see that stupid people worshipers are the problem, the more atheistic societies are smarter and they decrease their population, also they care about species in danger, and the opposite, stupid societies bad at getting science and thus believers ruin the Planet with their populational explosion, they are the pest you are talking about, and maybe you are part of them think about that.

The root cause IMNSHO, is not religion at all. It is in fact the geopolitical action of using birthrates as a weapon and source of profit in an endless quest for wealth. I seriously doubt most of the overall environmental assaults on the Earth and her inhabitants can be successfully quelled without at the minimum, a human population homeostasis or better yet, a reduction. I do not loathe the human race, but I do believe our unbridled success has become our greatest burden. Converting all the world's population to one religion and/or one government will not by itself solve the core issue.

That's why they haven't revealed the exact location. It's to protect the biodiversity. I, too, hope that they don't end up extinct. Especially given the fact that we know so little about them. At least this time they actually posted pictures of the newly discovered species in the article. The last article I read had no pictures at all.

Following on from the comments of Burnerjack and epsi00:

Exponential increase in the population size of a given species due to unrestrained growth are almost inevitably followed by a rapid crash as the capacity of the environment to sustain the rising population is exceeded.

Unless drastic measures are taken to curb and reverse the growth of the global human population, its current exponential growth dictates that we are fast approaching the point where it will crash in a profound and devastating manner.

Continued unrestrained growth of whatever form within the confines of an environment of finite resources is unsustainable. The sooner politicians in the various world economies wake up to this harsh truth and plan for a sustainable low-population future the better. By doing so they can avoid, or at least mitigate, the looming population crisis.

Large areas of forest all over the world are safe from developement due to the fact that many of the forests grow in places that are not suited for any type of human development. For example, of all the boreal forest land in British Columbia, only about 5% of that is aerable and suited for agriculture of any type. Modern forestry methods in industrialized countries is turning out to be a godsend (excuse the use of that term, lol) for the forests. It turns out that developed nations are reforesting rather than deforesting, which has had some unintended consequences like lake acidification from forest debris and water consumption problems too. Oh well, can't have everything.

In regard to population, people have been saying that we will all starve and wreck the planet for 100 years now. It didn't happen, and most experts agree that it won't. Some species are doomed. Oh well. Niche species never last long in nature anyway. BTW, we are part of nature you know.

The WWF, from which the above article comes, is only concerned with wildlife, but if I had to voice my most urgent worry in regard to humans, it would be fresh water. They almost touched on it above, when they commented on salt water intrusion, but water management isn't really the venue of the WWF. As people accumulate around coastal areas and drain the underground aquifers of fresh water, it allows salt water to move farther inland underground. It also tends to cause subsidence of the land at a rate as much as 20 times faster than the worst predictions of sea level rise. Then there's the issue of pollution of coastal water, also caused by human population concentration near coastlines, such as in Mexico and India. I would say that coastal urbanization is probably the biggest human caused problem in the world, not deforestation. Many rivers around the world don't even have year-round flow any more due to people using the water before it reaches the end of the river.

I don't know what experts you are talking about, but crop yields are quickly approaching their maximum and crops are being diverted to ethanol production, also, the population is 7 times greater than 100 years ago. There are limits to growth no matter how much you want to deny it. Look at how food prices have skyrocketed. Any change in weather is horribly disruptive to food supplies. People wouldn't have been so eager to riot in Egypt if they had lots of food. Pull your head out of the sand and take a look around before you say things like our food supplies aren't in danger.

They have printed studies about it here on Physorg in the past 6 months. You must not follow the litterature. The predictions are that improvements in crop adaptations, fertilizer, pest control, irrigation, automation of land husbandry, etc. will continue to increase crop yields at a rate sufficient to meet demand beyond the forseeable future.

The problem in the future for food is the same as it is today. It is poverty. The people today who cannot afford to buy food will still not be able to afford to buy food in 30 years. Here's an excellent NY Times article with some links:

So from reading a few of the links the mitigation of hunger relies on substantial investment in technology and resources. This will further increase the cost of food. You are correct in the statement that poverty is the problem. But with increased costs associated with food production, there will a greater number of people living in poverty. The people today who cannot afford to buy food will not be able to buy food in 30 years, and then add to this a substantial amount of people who can afford food now and who won't be able to afford it in 30 years. We won't all starve but more people will.

Take a look at Australia, South America, Canada, Africa, Russia, and the United States all of whose land area is mostly uninhabited and with today's technology you'll never convince me uninhabitable! But the prospect of expansion and of using our natural resources to do so is unthinkable to the socialist mindset: instead of allowing people to cut down trees and build, they'd rather them live in getto shacks!

You are missing an important factual point. Food is wealth. Take for example people living in China. As people in the countryside receive modern technology such as electricity and running water, they are able to grow more food and to grow food in places where they could not before. They are therefore actually producing their own wealth. Money actually does grow on trees, and in corn fields and in rice paddies. As those people gain access to new crop varieties which are resistant to pests, they no longer need so much pesticide. Better seasonal weather forcasts is also helping to decide what, when and how much to plant. Many of the new things that help to increase crop yield do not add any cost increase for those farmers in poor countries. For instance, they may not even know that they are using a new GM seed. They just bought it from the usual place.

If you look at a place like Sudan, the reason people are poor and starving isn't technology or money. That's an oil rich country. They were actually quite wealthy and modern less than a century ago. The problem is war. They burn the fields and blow up the oil pipelines, then they hunt herds of wild elephants and other wildlife to the point of extinction to feed themselves.

Look at North Korea versus South Korea. Same geography. North = starving. South = wealthy. The problem isn't the cost of food or the ability of the land to sustain agriculture.

If that is true, then it will be due to politics and economics, not agricultural capacity.

In a technologically backward place an average farmer is usually just barely able to support himself. There is no surplus. A bad year or two and he's dead. When modern technology is applied you start to have one farmer produce much more than he needs just for himself, a surplus. If someone else builds a storage facility, then you can keep the surplus on reserve. If a third person builds a transportation business, then you can move the surplus around. If a fourth person builds a store then you can sell it to people who do not farm. Then you suddenly have an economy that sustains itself. Like magic.

Here in South Carolina, for example, there are at least two species of large bats that they don't hardly know anything about. I saw one once and tried to look it up, but there's almost nothing known about it. It took years to prove the return of mountain lions to Kansas City, and people are now saying that the North Eastern mountain lion might not be extinct after 50 years without an official sighting.

As entertaining as the berating has been, I was looking forward to reading comments related to the article.

In an attempt to get back on track:
A likely reason why New Guinea has such biodiversity is the difficulty of the terrain which limits the migration of species and creates many mini-ecosystems.
As the island becomes more developed, these natural barriers will lessen. The biodiversity will suffer not just because humans will devastate some ecosystems, but because competition between species will increase. (IMO)

Part of it anyway. Another likely cause is a long term stable TROPICAL climate which allows species to specialize far more than species can do in a temperate climate with wide seasonal variation. Warmer on the south facing slope, well that means species don't have spend as much energy on keeping high temperature chemistry going. North slope species can get away with less UV protection. Not just for plants for smaller animals as well.

As the island becomes more developed, these natural barriers will lessen.
New Guinea really doesn't have all that much development. The diseases may keep it that way.
