Chilean authorities have removed the last known remaining specimens of a critically endangered frog from the wild in an attempt to save the entire species from extinction.The Loa frog is found in the riverways of the dry Chilean north and is now relegated to one known place, the drought-stricken Loa river in Calama. Due to the ongoing drought and threat to the species, Chilean scientists recently rounded up the last wild Loa frogs they could find – only 14 of them – and transported them to the zoo in Chile's capital, Santiago.
