All animals and plants have to be studied before they are put on an official list for endangered animals. It takes a lot of work and information to decide whether an animal is endangered or not. The International Union for Conservation of Nature (IUCN) has the biggest list of endangered species in the world, called the IUCN Red List. People use this list to make laws to protect animals, and to decide how to help animals that are in danger of becoming extinct.
The IUCN Red List puts animals and plants into 9 categories: Extinct (EX), Extinct in the Wild (EW), Critically Endangered (CE), Endangered (EN), Vulnerable (VU), Near Threatened (NT), Least Concern (LC), Data Deficient (DD), and Not Evaluated (NE). A species that is Critically Endangered has an extremely high risk of becoming Extinct in the Wild. Extinct in the Wild is just as bad as being Extinct, because it’s usually impossible to put enough animals back into the wild to save them.
Below, you will find a collection of animals that are Extinct in the Wild or Critically Endangered. Clicking on a set of animals will send you to a page with pictures and descriptions of each animal.
