A bamboo lemur is seen at the Andasibe-Mantadia National Park in Madagascar, March 29, 2025. Madagascar, an Indian Ocean island country, boasts unique biodiversity due to its geographical isolation, with lemurs standing out as the most iconic group. According to the International Union for Conservation of Nature (IUCN), over 100 species of lemurs have been identified on the island. Some lemur species have been listed as critically endangered on the IUCN Red List of Threatened Species due to habitat destruction and illegal hunting in recent years. (Xinhua/Li Yahui)
