( CNN ) -- The world has a new alliance to save vanishing frogs , toads and salamanders . A frog swims in a pond in Munich , Germany , in June . A coalition of organizations established the Amphibian Survival Alliance this month to conserve species threatened by deadly fungus , habitat loss , pollution , pesticides and climate change . The scientists said amphibians are the world 's most threatened group of animals . Though they thrived on Earth for more than 360 million years , one in three of the 6,000 recognized amphibian species are now at risk of extinction and as many as 122 species have gone extinct since 1980 , according to the International Union for the Conservation of Nature 's amphibian specialist group . `` The world 's amphibians are facing an uphill battle for survival , '' said James Collins of Arizona State University , co-chairman of the group . He said the new alliance , formed at the Amphibian Mini Summit at the Zoological Society of London , will focus efforts on the biggest threat to amphibians : infectious disease and habitat destruction . The group includes amphibian specialists working in the wild as well as those in zoos , aquariums and botanical gardens worldwide . `` Amphibians have so much to offer humans , '' said amphibian specialist Simon Stuart . `` Many have an arsenal of compounds stored in their skin that have the potential to address a multitude of human diseases . '' But as amphibians die out , so do opportunities to develop new medicines , he said . The southern gastric brooding frog , for instance , could have led to the development of a treatment for human peptic ulcers had it not gone extinct , Stuart said . `` We simply can not afford to let this current amphibian extinction crisis go unchecked , '' he said . Andrew Blaustein , who began documenting amphibian declines two decades ago , said the loss of species was part of an overall biodiversity crisis . `` Amphibians seem to have been hit the hardest of all vertebrate species , '' said Blaustein , a professor of zoology at Oregon State University . `` The long-term ecological repercussions of their decline could be profound , and we have to do something about it .
