Conservationists in fourteen countries around the world have launched an unprecedented search to rediscover as many as one hundred species of "lost" amphibians.

The quest to rediscover the lost amphibians will target the golden toad, gastric brooding frog, the hula painted frog and Jackson's climbing salamander.

The search has been launched after populations of the concerned amphibians suffered a shocking decline due to climate change. More than 30 per cent of all amphibians are at the verge of extinction.

The hula painted frog is believed to have disappeared in the mid-50s, while the Mesopotamia beaked frog was seen in Colombia in 1914 for the last time.

Amphibians play a crucial role in freshwater systems. Conservation International, which is leading the search in 5 continents, said that the study would provide important information for their survival.

Speaking on the initiative, the International Union for Conversation of Nature said, "The search for these lost animals may well yield vital information in our attempts to stop the amphibian extinction crisis.”

The study will also help researchers to better understand the impact that we are having on the planet.
