The second, I’m not sure exactly what the show is called, more than likely Animal Legends, Unlike the first it shows an actual real Wolf vs. Cougar fight. Pay close attention to the ending, maybe pausing it around 00:26, and from there it is easy to guess who probably won: http://www.youtube.com/watch?v=V5fBiKVQhO4&feature=related
Yes, I should have rephrased that, currently, yes, I actually have this conversation quite often, but this mainly because of coming across so many people who are a part of a “wolf cult”, or better known as “wolfaboo’s”
Lions are primarily pack hunters, though females do most of the work. A single lion can survive alone, but probably won’t take much big game. Tigers are mainly solitary hunters, though a female and offspring may hunt together.
The only dog-like sort of creature that has a chance against a lion is the hyena (because of its vise-like jaws), but that’s a slim one. There is footage of a hyena pack taking down an injured and sick female lion, but a male lion will tear a hyena apart in short order (there is also footage of that happening). The main thing to remember about big cats is that they have large muscle mass, and five of its six ends have long, sharp points, all of which are capable of ripping and rending. A wolf or any other doggy-type species relies on its teeth only.
Now, when you move down the predator scale to something the size of a cheetah, a hyena stands a very good chance. A cheetah will always run from a hyena that wants its food, since a broken leg means starvation. I’d say a wolf could probably run off a cheetah as well.
Most likely because there aren’t any wolves in Africa (at least Canis lupus). They do overlap in range in India, but lions have a very limited range there today.
Would it? A bear versus a lion? My money is still on the lion. In my totally unscientific opinion, bears seem slower and dumber. Are they that much more powerful, claws and teeth wise?
I’m not sure how seriously to take the TV show Animal Face-Off, but they concluded that a Siberian tiger could not do enough damage to a Siberian brown bear and that the bear would win in a fight.
For what it’s worth, the same show gives a cougar the edge over a wolf.
According to Stephen Fry on QI, an unscrupulous 19th Century San Francisco fight promotor once arranged a fight between a bear and a lion, the latter imported at great expense. The bear simple lumbered over to the lion, grabbed its head and crushed its skull, ending the fight in 30 seconds.
Really, all of these animal vs. animal fights can be answered with a single question: Which one weighs more. The more massive animal will almost always beat the less massive one.
There is, however, some range where the bigger animal might win, but would take significant damage. In this range, you’ll generally see animals try to avoid a fight if possible. This can come down to motivation: It’s not worth it to a wolf to try to fight a bear over a carcass, since the bear will probably win. But when it’s the wolf’s lair at stake, it is worth it for the wolf, but it’s no longer worth it for the bear.
