The emperor penguin and Antarctic fur seal have been officially listed as endangered, marking a significant conservation milestone as their populations face severe threats from climate change and disease. The emperor penguin, discovered in 1902 during Robert Falcon Scott's expedition, has seen a 10% decline in numbers from 2009 to 2018, with projections indicating their population could halve by 2073. Meanwhile, Antarctic fur seals, which rebounded to about 2.1 million individuals in 1999, have plummeted to around 944,000 due to climate-related changes affecting their prey, Antarctic krill. The increasing incidence of avian influenza is compounding these challenges, leading to high mortality rates among affected species. The urgent need for improved monitoring and conservation strategies is emphasized to protect these vulnerable marine mammals and their habitats in the rapidly changing Antarctic environment.
