Overview
- The IUCN Red List update Thursday reclassified emperor penguins and Antarctic fur seals as Endangered and moved southern elephant seals to Vulnerable.
- For emperor penguins, satellite images show about a 10% loss from 2009 to 2018, more than 20,000 adults, and models warn that repeated breeding failures on unstable “fast” sea ice could halve numbers by the 2080s.
- Antarctic fur seals have lost more than half their mature population since 1999, dropping from about 2.19 million to 944,000 in 2025 as warming seas and shrinking ice push krill deeper and farther offshore.
- Southern elephant seals were downgraded after H5 avian influenza killed up to 90% of pups in some colonies and hit breeding females, with major die-offs recorded in 2023 and 2024.
- WWF and BirdLife urged rapid emissions cuts and asked treaty parties to grant emperor penguins special protection at May 2026 talks in Japan to curb added pressures from fishing and tourism.
