it is not Tiger. It is a Cheetah. Cheetah is not fighter. Cheetah is fast and hunter but not figher. btw in this video if you look more close Cheetah attention was to cameramen because of that it lost control otherwise croco never able catch a fast cat like cheetah, cats are more clevers than corocos.

In first video above it is Jaguar which is always hunting to crocodiles. Jaguars favorite launch is crocodiles and they manages to hunt even more bigger crocodiles than itself are.
