One in five reptiles is threatened with extinction, according to The First comprehensive assessment of More Than 10,000 species across The World .

Scientists are calling for urgent conservation action for crocodiles and turtles, which are in a particularly dire situation.

They say reptiles have long been overlooked in conservation, because they are seen as less charismatic than " furry and feathery" creatures.

So Far , 31 species have gone extinct.

The study, published in Nature, took More Than 15 years to complete, because of problems getting funding for The Work .

" Reptiles to many people are not charismatic and there's been a lot more Focus On more furry, feathery species of vertebrates for conservation, " said Dr Bruce Young of The International nature organisation, NatureServe.

" The Hope is that we can really start making efforts to reverse this extinction catastrophe, " He Said .

The Final version of The Draft UN Convention on Biological Diversity (CBD) will be negotiated at the COP15 summit, which is expected to take place at The End of August.

The outcome will decide for The Coming decades how The World will address The Challenges of reducing the extinction risk threatening More Than one million species, eliminating billions of dollars of environmentally-damaging government subsidies and restoring degraded ecosystems.
