Food cycles and a hunger system for creatures

I have a suggestion giving the the different creatures a hunger system where the leviathans will get aggressive as the they get hungrier we will other creatures eating each other some unique animations like between the tar eel and the collecter like when one comes out of the tar to attack the player or any other reason the collecter will attack the tar eels grabing one to eat it this can be only one of the many interactions or the nibbler mangos swirling around prey to eat them
