Top Endangered Animals

Extinction occurs when every single member of a species has died and there are no living members of the species left. This can happen suddenly, like we all know happened to the dinosaurs, but can also happen gradually, allowing a species to become endangered before becoming extinct. This is an advantage to us, because we can recognize which species need to be protected before it's too late. However, there are a certain number of species that are critically endangered and on the edge of extinction.
