Elephants. Tigers. Gorillas. Pandas. Blue Whales. What do these amazing creatures have in common? They are some of the biggest, coolest, and most loved animals on the planet. They are all also endangered species.
An animal or plant is endangered when there are so few left alive on the planet that the entire species is in danger of vanishing forever. When a species is completely gone—and not a single one survives anywhere on Earth—it is considered extinct. Unfortunately, one out of every eight species of birds, one in four mammals, one in three amphibians, and one in five plants are endangered.
