Doesn't work like that. For animal testing, you need lots of animals. And endangered animals are by definition animals that you can't get lots of. So endangered animals aren't used in animals testing. Animals used in animal testing are species like rats, rabbits, dogs, some species of monkeys. All animals that can be easily bred in captivity. And not at all endangered as a specie.
