bald eagle
Humans are the answer! humans caused more animals to go extinct than any other animal.
Ivory billed woodpecker, there are less then 50 in the world.
you can't have an extinct animal living. It can be endangered or close to being extinct, but not extinct.
As with most extinct animals, humans are to blame for the quaggas' extinction. This animal was ruthlessly hunted for its meat and skin.
England
i think it will be elephant and after they are extinct then it will be leopard
There is no 'most extinct'. Once they are gone, they're gone. The most endangered great whale is the Western Pacific Gray Whale. See Related Links.
You don't. It is impossible to save an extinct animal. When something is extinct it is gone forever.
