Most Endangered Animals
An endangered species is an animal that is in danger of becoming extinct. The International Union for Conservation of Nature and Natural Resources (IUCN) reports that out of 63,000 species of animals and plants surveyed, more than 19,000 could become extinct!
That means one out of five mammals and one out of three amphibians are on the brink of extinction. Learn more about conservation efforts at Philadelphia Zoo and what you can do to help.
