Endangered Species Quiz
How well do you know the world's most vulnerable creatures and conservation efforts?
How well do you know the world's most vulnerable creatures and conservation efforts?
Over 44,000 species are currently threatened with extinction according to the IUCN Red List. This quiz draws from a pool of 50 questions covering critically endangered animals, conservation milestones, extinct species, and the science behind saving wildlife.
Each round presents 10 randomized questions from our pool of 50, making every attempt a unique experience. Select from four multiple-choice answers, receive instant feedback with in-depth explanations, and share your results to challenge others.
Questions span IUCN classifications, poaching and habitat loss, captive breeding success stories, mass extinction events, and landmark conservation laws. You might discover that the California condor was brought back from just 27 individuals, or that the northern white rhino has only two surviving members.
The IUCN Red List classifies over 44,000 species as threatened with extinction, including more than 41,000 categorized as Vulnerable, Endangered, or Critically Endangered. This represents about 28% of all assessed species. Amphibians are the most threatened vertebrate group, with roughly 41% of species at risk.
The vaquita porpoise is widely considered the most endangered animal, with fewer than 10 individuals estimated to remain in the northern Gulf of California, Mexico. The northern white rhinoceros is also critically close to extinction with only two surviving females. Among primates, the Hainan gibbon has roughly 30-35 individuals left on China's Hainan Island.
Scientists estimate that between 24 and 150 species go extinct every day, though the exact number is uncertain because most species have not yet been discovered or described. The current extinction rate is estimated at 100 to 1,000 times higher than the natural background rate, leading researchers to describe the present era as the sixth mass extinction event in Earth's history.
