3 Sloth bears eats monkey in Danish Zoo. Visitors shocked. This revives the old my animal vs. your animal debate. So who would win in a fight to the death, A full grown grizzly bears or a male silverback gorilla? Hmm the bears got claws and the gorillas a vegetarian. I think the bear can take on like 10 gorillas. But who knows, dolphins and killer whales do prevail over a great white shark.
