Its the pack. They say hyenas will take out a lion by circling it and constantly nipping at the lion's heels..everytime it will turn and snap at the hyena that was just behind it, opening up its back to another. Remove lion and insert gorilla, same result. Most things are stronger as a group, even people. The group wins99% of the time, so kiss the gorilla bye bye.

Only hope for the gorilla is to maul the first hyena that attacks so bad they all lose turn and run...not likely if they are hungry.
