London Zoo is celebrating the remarkable birth of 33 tiny endangered froglets, marking a significant milestone in conservation efforts for the species.
A Long Journey from Chile to London
The journey of these tiny froglets was nothing short of extraordinary. They traveled thousands of miles from the forests of southern Chile, having been carried and brooded inside their fathers’ vocal sacs for safety. This unique reproductive strategy is characteristic of the Darwin’s frog, a species named after the renowned scientist Charles Darwin, who discovered them.
Conservation Efforts Amidst Crisis
London Zoo announced on Monday that these 33 endangered Darwin’s frogs were born as part of a crucial rescue mission to save the species from extinction. Recent research indicates that known populations of Darwin’s frogs have suffered a staggering 90% decline within a year due to a lethal disease known as chytrid fungus, which infiltrated their habitat in the Parque Tantauco forests of southern Chile in 2023. This fungus has already impacted hundreds of amphibian species globally.
Heroic Conservationists
In a bid to find healthy Darwin’s frogs free from the infectious disease, a dedicated team of conservationists embarked on a mission to Chile’s forests in October. They successfully collected 52 frogs, which were then transported in climate-controlled boxes over a distance of 7,000 miles (11,265 kilometers) by boat, car, and plane to their new home in London.
Hope for the Future
Among those frogs, 11 males, each measuring less than 3 centimeters (1.2 inches), carried the 33 tadpoles that were subsequently born at the zoo. Ben Tapley, the curator of amphibians at London Zoo, remarked, “We knew we were embarking on something special — the clock was ticking, and we needed to act quickly if we were going to save these frogs.” He emphasized that the successful rearing of these froglets serves as a powerful symbol of hope for the species.
Creating a Sustainable Future
The newly born frogs are now housed in pairs inside dozens of glass tanks, complete with moss and environments that closely mimic their natural habitat. The zoo plans to establish a breeding program, with the goal of potentially reintroducing any bred frogs back into the wild. Andres Valenzuela-Sanchez, a researcher at ZSL (the conservation charity behind London Zoo), stated that this project is crucial for ensuring the species has a fighting chance for recovery.
“These frogs are not only vital for the future of their species but also help us better understand how we can combat chytrid fungus and safeguard other amphibians globally,” he added.
