Grizzly/Polar Bear vs Tiger?

The linked list seems pretty dumb. If the Inland Taipan (aka "Fierce Snake") is ranked fourth, a lot of the other hellers among venomous snakes--Black Mamba, King Cobra, Tiger Snake, etc.,--ought to be right up
there as well. A wolverine may well be pound for pound "tougher" than most other animals on that list, but it is certainly no match for a grizzly.

As to tigers killing grizzlies, in fact they do. In the Russian Far East, the Amur (aka "Siberian") tigers are known to prey on the Ussuri brown bears, sometimes called the "Black Grizzly." Males of this subspecies can reach 1,000 pounds. Whether the tigers ever seek out and kill the big males as prey or limit themselves to females and juveniles seems unclear.

I might add that that listing the polar bear as "tougher" than the grizzly is flat-out wrong. At the moment, grizzlies are encroaching more and more into polar bear habitat and sometimes hybridizing with the polar bears. Even though the polar bears are larger, they are gentler and less aggressive than the fierce grizzlies. I just read an article that says that the "mitochondrial Eve" of all polar bears was an Irish brown bear! Apparently this cycle of encroachment and hybridization have been going on for a long time. Polar bears, although very different in appearance, are descended from seagoing grizzlies and the two species are quite closely related.

We had a long thread awhile back about animals fighting, I remember. It was probably my all-time favorite thread in this forum.

First well-documented, modern case was in 2006 (http://news.nationalgeographic.com/n...id-photo.html). White fur, brown patches killed and verification of hybridization came after extensive study. Was apparently unexpected that it happened in the wild even though it has been documented in captivity. I don't see any mention of the bears size, I am almost certain that Polar Bears are significantly larger than all others. We should have seen this coming as we are melting their habitat.

tiger beats all mammals

^What about a Liger?

The Romans tried out most possible large mammals fights in the arena with real animals, including those bought in from beyond the boundaries of their empire. One of the roman writers recorded details of some of them, I forget the guys name but it shouldn't be to hard to find out with a bit of googling.
From what I recall reading large brown bears beat pretty much every other mammal they could find to throw at them in the arena.

In one fairly well researched secondary source about the Roman games, the author said the black rhinoceros was the most formidable combatant, which seems unsurprising. It easily disposed of such animals as the formidable aurochs and the brown bear.

All this irrelevant. Man with M-2 win.

^A "Ma Deuce" with tripod weighs almost 128 pounds. It might be just a tad unwieldy to deploy against, say, a charging tiger unless you were already set up for this scenario. Wouldn't a good dangerous game rifle be a bit more practical?

Grizzly or polar bear win. Just too big.

that's what she said.

tigers can ninja blend. polarbears/grizzlies can't.

Isn't a liger stronger than either of its parent species?
