Hello Johannes.

1. Leopard vs Okapi: The okapi weighs close to 3 times as much as a leopard (and perhaps more).  These 2 animals occasionally interact (leopards prey on okapis).  Leopards are agile, athletic, and powerful (can drag large prey items into trees).  They also have sharp teeth, sharp claws, and killing know-how.  Okapis battle other males by striking with their necks (like giraffes do), but they use strong kicks to deter predators.  They aren't as formidable (pound-for-pound) as many other herbivores (like zebras), but aren't helpless.  An okapi is capable of sending a leopard packing on occasion, but the cat will have the experience to complete a kill more times than not.  Edge to leopard.

2. Siberian Tiger vs Polar Bear: The polar bear will weigh over twice as much as the Siberian tiger.  Polar bears are very strong animals from nose-to-tail, and use this strength to accomplish many impressive feats (tackling walruses, pulling seals out of the water, bashing holes through thick ice).  They also have thick blubber under their fur.  Siberian tigers are among the largest of modern-day cats, and have typical felid attributes (speed, agility, athleticism, explosive movements, jaws & claws, killing know-how).  Big cats and bears usually match up well at similar weights, but a polar bear weighing over twice as much as a tiger will have too many advantages.  The bear will be much stronger, more durable, & have better stamina.  The Siberian tiger won't be able to control the positioning well enough to secure a finishing bite against this much larger mammal, and won't hold up against the bites & clawing of the ursid.  Polar bear wins.

3. American Lion vs Polar Bear: The polar bear will weigh much more than the American lion (approximately 50% more).  As in the last battle, the polar bear will be too big & strong for the American lion to easily control in order to secure a finishing throat bite.  The polar bear's forelimb/paw usage will give it an advantage at the point of contact, and its supple body will enable it to turn into the lion's attack (on most occasions) regardless of which direction it comes from.  The American lion will be quicker & more agile, but won't be able to consistently use these attributes to its advantage against this larger, stronger foe.  The lion can win, but it won't be able to on most occasions.  Polar bear wins.

4. Smilodon Populator vs Polar Bear: The polar bear will be about 70% heavier than the Smilodon.  Smilodon populators were probably the strongest felids ever, and had stocky bodies packed with muscle.  They killed prey items much larger than themselves, and did so by wrestling them to the ground with their forelimbs & claws and finishing them with a bite to the throat (or other vulnerable area) with their long upper canines.  This specialized method of killing worked well against Smilodon's targeted prey items (bovids, equids, etc.) as they could be brought down consistently.  A polar bear, however, will be difficult to wrestle into a vulnerable position due to its great strength & paw usage.  The polar bear will control the point of contact well enough to keep the Smilodon's "sabers" at bay, and its greater endurance will enable it to eventually wear the felid down.  The Smilodon certainly can win, but it won't be favored.  Edge to polar bear.  

5. Grey Wolf vs Common Chimpanzee: These animals will weigh about the same (59kg) at typical top weights, but a chimpanzee can be slightly heavier on occasion.  Grey wolves are excellent pack hunters and don't usually engage adversaries solo, but can be capable fighters with their good endurance, decent lateral movement, & big bites.  Chimpanzees aren't practiced at fighting another species of similar size solo, and usually use intimidation before getting physical.  Each animal only has its bite as an offensive weapon, and the wolf's is more formidable.  The chimpanzee will likely be able to deter a solo wolf from attacking, but if the wolf is determined to proceed, it will try to dart in and out and land bites when it can.  If it can wear the chimp down, it will go in for a finishing bite.  The chimpanzee will use its arms (and strength) to control the movement of the wolf and try to land bites of its own.  At parity, this is a close fight, but the wolf is a predator and will likely have a better chance of finishing the chimp than the other way around (chimps don't have good "finishing" ability).  A realistic encounter will slightly favor the chimp (it will persuade the wolf to retreat); a fight to the finish will slightly favor the wolf.  Overall edge to grey wolf.

6. Pantanal Jaguar vs Marsupial Lion: These animals will be about the same weight.  Jaguars are muscular & powerful felids with large heads & very strong jaws (capable of crunching through turtle shells & caiman armor).  They typically kill by biting the skull or spinal column of their victims.  The marsupial lion (Thylacoleo carnifex) also had a powerful, stocky build and a very strong bite force (likely higher than the jaguar's).  Its jaws were cat-like, and it was capable of subduing prey animals much larger than itself.  At one time it was thought by some that the marsupial lion may have been a fruit-eater, but wear found on its formidable teeth proved otherwise.  The jaguar probably has the edge in quickness & agility, but the marsupial lion has a more dangerous bite (overall) in this particular battle.  Close to 50/50.

7. Indian Wolf vs Dhole: The Indian wolf will weigh approximately 30% more than a dhole.  Indian wolves can be aggressive, and sometimes attack livestock.  Dholes are feisty, persistent predators that hunt in large packs to overpower prey items of decent size (cervids, bovids, suids, etc.).  Dholes have short, stocky jaws (compared to the wolf's longer jaws) and can deliver a powerful bite.  Close fight at parity, but the Indian wolf has too much of a size advantage here.  Edge to Indian wolf.

8. Grizzly Bear vs 2 Eastern Gorilla Silverbacks: A grizzly bear can weigh over twice as much as an Eastern gorilla.  Grizzly bears are among the most aggressive of bears, and rarely back down from a conflict.  They have a huge shoulder hump of muscle that enables them to easily dig up tough earth, and gives them great power when swiping with their forelimbs.  Grizzly bears have claws on each paw that can exceed 4" in length, and these can be mighty weapons.  Gorillas are very strong primates with long arms & decent bites.  They aren't experienced at battling other species of animals, and most conflict between troops are primarily intimidation.  2 gorillas won't work as a team the way a couple of grey wolves or lionesses will, and won't have an effective means of tackling a grizzly bear.  The bear can seriously injure a gorilla with its weaponry, and its endurance will enable it to battle strongly for a long time.  Grizzly bear wins.  

9. Snow Leopard vs Komodo Dragon: These animals will be similar in weight, but a komodo can potentially get over 20% heavier.  Snow leopards have typical felid attributes (speed, agility, athleticism, killing know-how), and can kill prey animals several times their own size.  Komodo dragons are the world's largest lizards, and are very capable predators.  They have sharp teeth (1" long), toxic bites, whip-like tails, sharp claws, & tough hides (covered with small osteoderms).  The snow leopard will have enough quickness (on most occasions) to avoid the komodo's bite and jump on its back, but may not be able to escape getting bit at some point during the struggle.  The snow leopard should be able to subdue the Komodo dragon with its claws & teeth, but will eventually die if it receives a deep bite.  Overall, snow leopard wins.

10. Spotted Hyena vs Giant Anteater: The spotted hyena will usually weigh over 50% more than a giant anteater, but these 2 can be close in weight if the anteater is at its maximum size (at which point the hyena will still be about 10% heavier).  Spotted hyenas are durable predators with very strong jaws (can crush bones at a carcass), and can hunt in groups to bring down larger animals.  They are battle-tested, often dealing with lions, leopards, and other formidable African adversaries.  Giant anteaters have huge claws on their forelimbs that are primarily used for digging, but can be utilized as effective weapons to repel jaguars & cougars.  A spotted hyena is somewhat ungainly in its movements, but it will still have comparable lateral movement (to the anteater).  The hyena will be vulnerable to the slashes of the anteater if it comes close, and will likely be driven away in a realistic encounter.  A determined hyena can secure a bite on a smaller anteater, but will have trouble with one close to its own size.  At equal weights it will be close to 50/50, but with the hyena having a slight weight advantage at worst, it will have a slight edge if it's determined to battle to the end.  The hyena will have an edge in stamina, and will gain more of an advantage in a prolonged fight.  Edge to spotted hyena.

*** Main event ***

Smilodon Populator vs Giraffe: A large giraffe can weigh 3 times as much as a Smilodon populator, and some bulls may be over 4 times as heavy.  Smilodons populators are stocky, muscular cats that have long upper canines used to dispatch prey items.  They typically wrestle their quarry to the ground by using their powerful forelimbs (and claws), and get into a favorable position to deliver a fatal stab to a vulnerable area (typically the neck area).  Smilodons aren't quite as agile & quick as modern big cats, but are much stronger & better armed.  Giraffes are the tallest animals in the world today, towering over 5 1/2 meters on occasion.  They often deal with attacking lions, and a large group of these cats is typically needed to subdue one.  Giraffes can deliver a powerful, bone-shattering kick (especially with their hind legs) to defend themselves from attack, and their vulnerable necks are usually high enough to remain safe during any conflict.  A Smilodon may not be swift, but has large leg muscles, and was likely a strong leaper.  It will have trouble avoiding the kicks of the giraffe, but will have the ability to leap upon the giraffe's side (and perhaps its back) if it calculates carefully.  The Smilodon will then need to hold on tight enough to climb to the giraffe's neck, and this may be difficult to do while the herbivore is violently resisting.  The heavy-bodied Smilodon may not be able to hold its own weight up while trying to advance its position, and toppling the huge herbivore isn't likely.  Smilodons are practiced at overpowering large prey items, but this particular one offers a unique challenge due to its height & build.  The Smilodon populator can pull this off, but a large bull will be too strong & dangerous to consistently overcome.  I favor the Smilodon against a giraffe 3 times as heavy, but once the ruminant approaches 3 1/2 to 4 times as heavy, the tide will likely turn.  Close to 50/50 (overall); slight edge to giraffe.

Best regards.

Questions regarding animal conflicts within realistic or unrealistic settings are welcome; my strength lies in medium-to-large species. Small animals (including birds of prey), prehistoric animals, sea creatures, and domestic dog breeds are usually within my scope, but to a lesser degree. I can't confidently answer hypothetical questions about human vs animal, arachnids, insects, or amphibians, but I am willing to field them nonetheless.


From a young age, I have been interested in animals. Starting with the original Mutual of Omaha's Wild Kingdom and World Book Encyclopedias, I have seen many animal shows and documentaries and have read multiple books on the subject. I have a solid understanding of the physiology of many animals and interspecies conflict in general.
