Small but tough, they fight off big predators like lions.
Strong and fierce, they'll stand up to other animals.
Big and territorial, they'll attack anything they see as a threat.
Huge reptiles that can easily kill.
Big birds that will attack if scared.
Apex predators that hunt prey, including humans.
Venomous snakes that can kill quickly.
Small bears that can be aggressive.
