Hey Simon

1. The bear should be too much for the tigers but as most people know, tigers are capable of pulling off very impressive kills so between two this is certainly possible.

2. I'd probably switch to the tigers here. They are quite large for their sub-species, and the bear isn't quite so big for its sub-species. Still could go either way

3. At double the weight I find it hard seeing the bear lose. But it is a jaguar, so pretty much everything will have a battle on its hands.

4. The jaguar should beat this fairly lightly built bear.

5. I think I'd go with the jaguar again. The bear will lack the dynamic attack of the jaguar and will not have the raw strength and size of a larger or different bear species to counter that.

6. I highly doubt the sun bears would be able to do enough damage quick enough. At double the weight, the cat should be able to kill a sun bear quite quickly.

7 and 8. I'll say the bears in both cases, but they will have some shocking injuries if they do win.

9. Lion for me. At these kinds of weights, I think lions are far superior to bears.

10. Lion vs tiger is 50/50 for me, so 40lb advantage = lion win.

11. The bear can and might win on occasion but more often than not the boar will rough it up a bit and leave. Very difficult animal to control and offensively very dangerous.

12. I doubt the bears would have the cohesion required to counter the enormity of their opposition. If they did happen to work together they would win, but they won't.

Cheers Simon

I can answer most questions relating to real or hypothetical situations. I have a better understanding of animal behavior and specifically predatory behavior and interspecies predatory relationships. Mammals is my field of expertise but I can do my best in answering questions regarding other animals. Small mammals are my favourite matchups. One or two prehistoric match-ups is OK, but please do not focus on them as they are outside my expertise.


Even before completing my degree I considered myself an expert in mammal behavior. Doing my degree only furthered my interest and knowledge in the subject. After uni I got the opportunity to spend 6 months in South Africa and Kenya where I spent nearly every day basically observing and studying the animals of the savanna.

BSc Degree in Zoology from the Melbourne University, Australia.
