Wildlife activists say they have rescued what may be the world's last surviving members of a highly endangered species of water frog.They captured 14 Loa water frogs earlier this month in northern Chile,which are listed as “critically endangered”.The 14 frogs were in poor condition when they were discovered.

The Loa water frogs are known to live only in a single body of water near Calama,in Chile.The city sits in the middle of the Atacama Desert,where water is in great demand.The frogs'environment had mostly dried up because water is being taken away and used for human activities,including mining,agriculture and land development.“All of the frogs had been pushed into a tiny pool of muddy water,”the organization said.“The team collected the last 14 individuals and brought them to the National Zoo of Chile to start a conservation breeding program.”

Zoo specialists are closely watching the small creatures and trying to give them everything they need to survive and be healthy.The team said it had contacted water frog experts from around the world to seek advice for their efforts.Zoo workers plan to launch a mating program for the frogs in an attempt to expand the population.

“The first big challenge is to help these frogs survive,”said Alejandra Montalba,director of the National Zoo of Chile.“While the rescue has taken the best chance to save the Loa water frog,there arealways risks with trying to care for a new species—especially when the animals are already struggling.”

Conservation groups have called on Chile's government to take steps to halt any illegal water usage that threatens the frogs'natural environment.They would also like to see creation of a government-supported shelter to protect the animals.
