In fact, some of them are so rare that people have to protect them by law.
Here are a few examples of rare wild animals you might've heard about.

The Sumatran orangutan is a critically endangered species of ape that inhabits the rainforests of Sumatra, an island in Indonesia.
Their numbers have drastically decreased due to habitat loss and illegal hunting.

The vaquita is a small porpoise species found in the Gulf of California, Mexico.
It is the most endangered marine mammal in the world.
