Missing Frogs Legs!

Scientists think they have resolved one of the most controversial environmental issues of the past decade: the curious case of the missing frogs' legs. Around the world, frogs are found with missing or misshaped limbs, a striking deformity that many researchers believe is caused by chemical pollution. However, tests on frogs and toads have revealed a more natural, benign cause. The deformed frogs are actually victims of the predatory habits of dragonfly nymphs, which eat the legs of tadpoles. * BBC, Full Story Here.. http://news.bbc.co.uk/earth/hi/earth_news/newsid_8116000/8116692.stm

Meanwhile according to the BBC, a new study has shown up to one billion frogs are taken from the wild for human consumption each year. About one-third of all amphibians are listed as threatened species, with habitat loss the biggest factor. But hunting is acknowledged as another important extinction driver for some species, including frogs, along with climate change, pollution and disease - notably the fungal condition chytridiomycosis which has brought rapid extinctions to some amphibians. The article also states that a large portion of the trade in amphibians for the pet trade is conducted illegally, and experts say customs officials in many countries are ill-equipped to spot and deal with illegal consignments. *
