Five Mammals We May Never See Again

Data released by the International Union for Conservation of Nature (IUCN) shows that more than a quarter of the world's mammal species are at risk of extinction. Among the 5,899 mammal species assessed in this research, 235 species are in a 'critically endangered' status. The Bactrian camel, once widespread across the Middle East to northern China, has been critically endangered since the 1960s and was designated as 'critically endangered' in 2002. The IUCN estimates that currently, fewer than 1,000 of them live in areas of the border deserts of China and Mongolia. Experts say these rare camels are in critical condition due to their high value in illegal markets and competition with domestic camels for water and food. The Javan rhinoceros is the rarest large mammal on Earth. This species of rhinoceros, native to Asia, was once seen across a wide range from the islands of Indonesia to South Asia and India and China. However, currently, fewer than 70 remain, and the entire population of this rhinoceros is concentrated in a small area, making them highly vulnerable to natural disasters and diseases. The northern white rhinoceros can be considered nearly extinct. With the death of the last northern white male rhinoceros in 2018, this massive mammal is in a state of 'functional extinction,' with only two female animals of this species remaining. Scientists are trying to recover it using fertilized eggs of this rhinoceros and implanting them in the womb of the southern white rhinoceros, but experts say these solutions are as difficult as the mammoth revival project. According to the Convention on International Trade in Endangered Species, Chinese pangolins are the biggest victims of trafficking and illegal hunting among mammals. Although numerous efforts have been made to protect this animal through strict laws, some people in China still consume Chinese pangolin meat, and its scales are used in traditional Chinese medicine. In eastern Nepal, the scales of this animal are carried as lucky charms, which has fueled their hunting. It is unclear how many Chinese pangolins remain, but their presence has been limited to areas in China, Vietnam, and Laos. The sifaka is a type of primate and a relative of modern humans that has played a significant role in scientists' understanding of human evolutionary history. These exceptional animals are sources of study regarding visual evolution, color perception, and matriarchal societies. Due to their interesting appearance, they have also been actively featured in children's programs and animations. However, the habitat of sifakas is limited to Madagascar, and illegal hunting and habitat destruction have placed them on the red list of animals that are critically endangered. Conclusion: Mammals are the most advanced vertebrates on Earth and play a key role in maintaining ecosystem balance and ensuring the biological health of natural environments. However, there is also good news. Nine out of ten mammal species that entered the IUCN red list between 2022 and 2024 are showing signs of improvement. The number of endangered mammal species worldwide has decreased in the last two years. Currently, 1,338 mammal species are on the IUCN red list. Scientists say that climate change, habitat loss, pollution, and human activities such as hunting and deforestation are among the main factors of this crisis.
