Wildlife activists say they have rescued what may be the world’s last surviving members of a highly endangered species of water frog. A team of conservationists captured 14 Loa water frogs earlier this month in northern Chile, a wildlife group reported. The team also included representatives of Chile’s government. There are more than 60 known species of water frogs. The amphibians live in several countries in South America. The International Union for Conservation of Nature (IUCN) lists the Loa water frog as “critically endangered.” The not-for-profit Global Wildlife Conservation group said the 14 frogs were in poor condition when they were discovered in late June. The animals were small and struggling because of a lack of food and water.
