Top 10 Most Endangered Species

Roughly 120 adults survive in the wild across the Russian Far East and northeast China, threatened by habitat loss, poaching, and inbreeding depression.

Palm oil plantations have decimated their rainforest habitat in northern Sumatra, leaving fewer than 14,000 individuals in fragmented forest patches.

Hunted for their ornate shells and losing nesting beaches to coastal development, hawksbill populations have declined by over 80 percent in the last century.

The world's most endangered marine mammal has fewer than 10 individuals left in Mexico's Gulf of California, victims of illegal gillnet fishing for totoaba.

Around 1,000 mountain gorillas survive in the Virunga Mountains and Bwindi Impenetrable Forest, a rare conservation success story driven by ecotourism revenue.

Discovered in Vietnam in 1992, this elusive forest-dwelling bovine has never been reliably counted, and scientists fear fewer than 100 remain in the Annamite Mountains.

Only around 300 individuals persist in the forested hills along the Nigeria-Cameroon border, threatened by habitat conversion and hunting.

Roughly 1,000 of these freshwater cetaceans survive in China's Yangtze River, where pollution, ship traffic, and dam construction continue to degrade their habitat.

Habitat loss from logging and agricultural expansion has halved their population in one generation, with fewer than 2,800 remaining on the Indonesian island.
