There are several different species of Pangolins around the world. According to the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species, there are eight different types of Pangolins under the Manidae family. Most of them are classified as “Near Threatened,” “Endangered,” or “Critically Endangered” by the IUCN. Pangolin populations have been noticeably decreasing in population, with suspected declines of up to 50% over the last 15 years.
Exact population levels are unknown for Pangolins. They are very reclusive, and their nocturnal nature makes them extremely difficult to track for a comprehensive population estimate. In recent years, growing concern over Pangolin trafficking and noticeable population decline have prompted research to verify their population, but no complete data has been finalized yet. Initial studies have revealed that Asian species of Pangolins are declining in population at a more rapid rate than other species of Pangolins.
