The hippopotamus - is actually a very aggressive and dangerous animal, will attack boats and kill the passengers. And it out weighs the gorrilla by a few tons, has fangs about the size of a gorilla .
A rhino could flip a gorilla
A gorilla has no chance to fight a rhino.
In a fight? The rhino.
I would think the giraffe would win. Even though the rhino is powerful, it is not very fast. For a lion, getting kicked by a full grown giraffe is usually fatal, and despite the rhino's protective coating, the giraffe would see it, and be ready for attack.
The Rhino would win. The Rhino can knock the Buffalo with his horn and Rhino are stronger than Buffalo.
a silver back gorilla would win easily win!
The Thing.
triceratops
