Tadpoles try to flee dangerous virus in their pond by growing much faster than normal, research shows

The world's amphibians are in trouble. Because of their sensitivity to climate change, habitat loss, and pollution, they may be the canary in the coal mine for the nascent anthropogenic mass extinction. Approximately 200 amphibian species have become extinct since the 1970s, and the International Union for the Conservation of Nature estimates that 34% of the 7,296 known remaining species are likewise at risk.
