I'd bet on the bear; a larger and heavier bulk of a beast.
A full grown Jaguar could beat a Black bear, but would lose from a Grizzly.
the bear could win or the jaguar. it's a 50/50 chance. The bear is bigger, but the jaguar is faster. so it's a tough call if he'd even get the chance to or not.
The grizzly bear would win because the jaguar, though ferocious, would realize it is not a match for the bear. The grizzly can stand 4 feet tall on its own 4 feet. The largest grizzly in Alaska stood 10 feet tall and 1200 pounds.
It would vary, if it was a polar bear, no chance for jaguar, if it was a black bear 4/10 would the bear win because the black bears is one of the smartest animals in the animal kingdom. But jaguar vs grizzlie, it would be 40/60 in favor of bear just because of their size and their strength. Hope this answered your question :).
jaguar
Definitely the bear would win.
The atlas bear would win.
caiman would win
A single bear would win against a single wolf.
The black bear would win.
A elephant because it is one of the largest animals alive today. If it was a baby elephant i do believe a jaguar would win.
The grizzly bear would probably win
