Ursus arctos pruinosus posted in the Polar Bear section: I have read the thread regarding the sloth bear aggression account. Essentially they have aggressive interactions with tigers and even to elephants and rhinos at times. This has got me wondering if polar bears have ever shown aggression towards mammoths and rhinos (e.g. a male polar bear driving away a woolly mammoth or rhino which comes too close or a female polar bear attacking one of the two large mammals to protect her cubs). Note: I have read bits and pieces ( hints ) of this. Any info concerning sloth bears and elephant or rhinoceros, post here.

en.wikipedia.org/wiki/Sloth_bear Asian elephants apparently do not tolerate sloth bears in their vicinity. The reason for this is unknown, as individual elephants known to maintain their composure near tigers have been reported to charge bears. The Indian rhinoceros has a similar intolerance for sloth bears, and will charge at them.

Looks like elephants and rhinos see sloth bears as a threat. But they have more caution with tigers of course.

That is really surprising as sloth bears normally feed on termites, fruit, and occassionally carrion. I wonder?

SLOTH BEAR CHASING A SMALL ELEPHANT

Now we know that sloth bears can't kill elephants but the account of the bear chasing an elephant was nevertheless impressive. This makes me even more certain that Pleistocene grizzly bears chased off mastodons that come too close occassionally and an extremely hungry polar bear might attack a woolly mammoth (but fail to kill the pachyderm of course) once in a blue moon. Sloth bears just like the barren ground grizzly bears don't really tolerate much it seems.

And the key word there is “tolerate”. nope, they dont tolerate absolutely nothing. That is why in India the sloth bear is more feared than bengal tigers. When i saw the sloth bear in the Berlin zoo, it was in the most secure enclousure out of all animals, it had like a very thick glass, almost bulletproof glass or something.

I have read bits and pieces about the strange relationship between sloth bear and elephant. But I have no specifics.

Apart from the sloth bear, the brown bears, black bears, and polar bears have also encountered pachyderms in the past which are now extinct (mastodon, woolly mammoth, woolly rhino etc).

Bear and Elephant relations... a very mysterious INTERSPECIFIC relationship. Any information appreciated.

I have been searching for interactions too but it seems I am finding one. Brown bears and polar bears have encountered mammoths. My guess, mammoths and mastodons despite being big and strong actually respect the bears especially an aggressive mother protecting her cubs.
Despite being unable to kill the mastodons and mammoths, I am not surprise if brown bears like the grizzly bears use their aggression to get their way around due to being unable to climb like the American black bears. An extremely hungry polar bear might even attack an adult mammoth the same way one attacked a bowhead whale despite the fact the bear will obviously fail.

en.wikipedia.org/wiki/Sloth_bear Relationships with other animals The large canine teeth of sloth bears, relative to both its overall body size and to the size of the canine teeth of other bear species, and the aggressive disposition of sloth bears, may be a defense in interactions with large, dangerous animals, such as the tiger, elephant, and rhinoceros. Asian elephants apparently do not tolerate sloth bears in their vicinity. The reason for this is unknown, as individual elephants known to maintain their composure near tigers have been reported to charge bears. The Indian rhinoceros has a similar intolerance for sloth bears, and will charge at them.

This really is a mistery. Sloth bears are not "predators", and they are not a threat to elephant calves. So i dont see a reason why elephants would not tolerate sloth bears. Are we sure that phrase from wiki is accurate?
