Wildlife officials in Peru are investigating the mass death of thousands of rare frogs near the Bolivian border.
Locals estimate that the bodies of some 10,000 Titicaca water frogs have been found in Lake Titicaca and its adjoining rivers.
The critically endangered amphibian, known as the ‘scrotum frog’ due to its unfortunate appearance, is believed to have been killed by polluted waters.
Thousands of the large, wrinkly green frogs have been found floating on the surface of the Coata river in southern Peru in recent days, prompting the National Forestry and Wildlife Service (Serfor) to launch an investigation.
‘Based on local residents’ statements and samples taken in the days after the incident, it is believed that more than 10,000 frogs were affected over about 50 kilometers (30 miles),’ Serfor said in a statement.
The alert was sounded by an environmental group called the Committee Against the Pollution of the Coata River, which accused the authorities of ignoring the river’s severe pollution.
To protest, its supporters brought 100 of the dead frogs to the central square in the regional capital, Puno.
Protest leader Maruja Inquilla urged the authorities to take the dead frogs as a wake-up call.
‘I’ve had to bring them the dead frogs,’ said Inquilla.
‘They have no idea how major the pollution is.
‘The situation is maddening. Why is the state so apathetic?
The frogs live only in Lake Titicaca, South America’s largest lake, and its tributaries.
Known officially as Telmatobius culeus, the amphibians got their nickname from their many folds of skin, which help them breathe in their high-altitude habitat in the Andes mountains, more than 12,500 feet above sea level.
The species is classified as critically endangered by the International Union for Conservation of Nature, which says the population is estimated to have declined by 80 per cent in the past 15 years.
