Interspecies Conflict/Random Question @ Balanced and Unbalanced matchups


Hi there happy independence day even though it was yesterday. Just thought I'd say that.

Random Question. We both know that an adult human is no match for a chimpanzee physically. But what about bite force? In the Guinness world records it mentions a man who eats metal with a 52 ton per square inch bite force. If this particular man bit  into the neck of a chimpanzee with all that metal breaking jaw power could he subdue it? He'd get seriously messed up in the process I know but could he kill it? I also hear humans have a bacterial bite that rivals that of the komodo dragon!

Hello, Max.  Happy Independence Day to you.

Q: We both know that an adult human is no match for a chimpanzee physically.  But what about bite force?  In the Guinness world records it mentions a man who eats metal with a 52 ton per square inch bite force.  If this particular man bit into the neck of a chimpanzee with all that metal breaking jaw power could he subdue it?  He'd get seriously messed up in the process I know but could he kill it?  I also hear humans have a bacterial bite that rivals that of the komodo dragon!
A: There may be a few humans on the planet that could subdue a chimpanzee, but you're right, an adult human is typically no match for one physically.  If a man did indeed have a 52 ton per square inch bite force, he would be able to kill a chimpanzee with one bite in the right location.  However, the average bite force for a human is about 150lb, and I'm quite sure 52 tons per square inch is not an accurate measurement for a human.  A Tyrannosaurus doesn't have a bite force close to that!  Anyhow, even if a man had that high of a bite force, getting into position to use it on a chimpanzee would be a serious challenge.  This man would need to bring a lot more to the table (fighting ability, high level of physical strength, mental toughness, etc.) & to have a chance of delivering this bite.  Humans do have nasty bites, but they're not as potent as a Komodo dragon's bite.  A komodo's teeth are about an inch long, and very sharp.  In addition to the bacteria that exists, Komodos dragons deliver a toxin that induces shock in victims.  I have heard that a human bite is nastier than a dog's bite, but I'm not sure about that one.

1. Suchomimus vs. Oxalaia: Both of these Spinosaurus-like creatures were similar in size, and had similar attributes (long, narrow jaws full of pointed teeth designed to grasp scaly prey, forelimbs with claws).  Size estimates vary on both, so the larger one would likely prevail in a battle.

2. Daspletosaurus vs. Mapusaurus: Mapusaurus was slightly heavier than Daspletosaurus.  Both had fearsome jaws, but the size advantage of Mapusaurus would make a difference more times than not.  Edge to Mapusaurus.

3. Gorgosaurus vs. Albertosaurus: These theropods were the same size, and were very similar in attributes & abilities.  The jaws of Albertosaurus may have been a little better.  Slight edge to Albertosaurus.

4. Deltadromeus vs. Allosaurus: These theropods could be close in weight on occasion, but Allosaurus was typically between 15-35% heavier.  Both had deadly bites, but Allosaurus would be able to use its greater power to prevail more often.  Allosaurus wins.

5. Dryptosaurus vs. Ceratosaurus: Ceratosaurus would probably be favored at parity, but Dryptosaurus at least 20% heavier (and may have been as much as 75% heavier).  Both had large jaws with sharp teeth, but the larger dinosaur is favored.  Dryptosaurus wins.

6. Yutyrannus vs. Afrovenator: Afrovenator was lightly built, and wasn't as heavy as Yuthyrannus.  Afrovenator had sharp teeth (about 2" long) and hooked claws, and was believed to predate upon the sauropod Jobaria (which reached 20 tons in weight).  Yutyrannus had large jaws as well, and had enough size (perhaps 50% more) to consistently win here.  Yutyrannus wins.

7. Sinotyrannus vs. Utahraptor: Sinotyrannus had a significant weight advantage over Utahraptor, but was not as well-armed.  Sinotyrannus had a large set of jaws, but Utahraptor was an agile theropod with decent jaws of its own, claws on its forelimbs to grab with, claws on its hindlimbs to kick/slash with, and good leaping ability.  Utahraptor would make a good fight of it, but one chomp of the jaws of the much larger Sinotyrannus would likely end it.  Sinotyrannus wins.

8. Monolophosaurus vs. Dilophosaurus: These dinosaurs were similar in size (and both had crests on their heads), but Monolophosaurus had a stockier build and may have weighed up to 50% more.  Monolophosaurus wins.

9. Sauroniops vs. Saurophaganax: Sauroniops had a long skull for a theropod, and jaws full of bladelike teeth.  It had a decent size advantage over Saurophaganax, and would likely be favored against it.  Sauroniops wins.

10. Acrocanthosaurus vs. T Rex: Tyrannosaurus was at least 25% heavier than Acrocanthosaurus, and both had similar attributes.  The bigger dinosaur will have the advantage.  Tyrannosaurus wins.

Unbalanced Matchups

1. Kodiak Bear vs. Bull Elephant Seal: A Northern elephant seal weighs over 3 times as much as a Kodiak bear, and a Southern elephant seal weighs over 5 times as much.  Elephant seals fight by rearing up to face one another, and forcefully crashing their upper bodies into their opponent while attempting to deliver a bite.  These battles can be rather bloody.  Kodiak bears are powerful mammals with great strength, endurance, durability, & weaponry (strong jaws & long claws).  A swipe from a bear's paw can have a profound impact on most targets, but an elephant seal is much larger than anything a Kodiak bear encounters.  Polar bears struggle to overpower walruses of similar size, and they have experience dealing with pinnipeds.  Kodiak bears don't.  A determined Kodiak bear would have the arsenal to compete with a Northern elephant seal if its weaponry was coupled with experience, but even then it would be bullied around on most occasions.  A Southern elephant seal is simply too big.  Although not as well-armed as a walrus, a bull Southern elephant seal would have little to worry about from a bear.  It won't be able to subdue a bear, but it will drive it away.  Elephant seal wins.

2. Giant Panda vs. Spotted Hyena: A giant panda can weigh twice as much as a spotted hyena.  Giant pandas seem nice & cuddly, but can be dangerous if threatened.  They have strong bites, and can cause a lot of damage with their swiping claws.  They rarely encounter predators (wolves & leopards are around, though), but they have typical bear attributes (strength, durability, stamina, etc.) that will serve them well in an encounter.  Spotted hyenas are very durable predators that have very powerful bites (can crush bones at a carcass).  They are battle-tested as well, dealing with African hunting dogs, leopards, lions, and other dangerous African creatures.  Hyenas are somewhat clumsy in their motion, and don't have the same level of lateral quickness as, let's say, a wolf.  Hyenas are better tackling adversaries as a team, but are still capable of holding their own solo.  A giant panda will use its claws to repel an attacking hyena, and can physically overpower it if it comes too close.  A sun bear, which is close to a spotted hyena's weight, is a better match for it.  Giant panda wins.

3. Polar Bear vs. Bull Shark (in 6 feet of water): A polar bear weighs 3 times as much as a bull shark.  Polar bears are great swimmers, but can't call upon their legendary strength in a water battle if they can't easily touch the bottom.  A polar bear is about 5' tall at the shoulder, and would need to stand upright to keep its head out of the water.  The bull shark won't have the greatest vertical mobility in this water depth, but will still have decent lateral movement.  A paw swipe by the bear won't be very effective against a submerged opponent, but a bite from the shark's razor-sharp teeth can seriously injure the mammal.  Polar bears have sharp, curved claws (2" long) that are perfect for gripping ice & pulling large seals & cetaceans out of the water, and could theoretically do the same to a bull shark if it had some land (or ice) to pull it onto.  The polar bear may use its paws to seize the shark and hold it in place while it bites, but this action may require the polar bear to submerge.  It can subdue the shark in this manner, but whether or not it will actually do this is another matter.  Sometimes the shark will get enough bites in to win; other times it will be physically overpowered & defeated by the larger bear.  Interesting fight; close to 50/50.

4. Polar Bear vs. Sarcosuchus: Sarcosuchus (also known as "SuperCroc"), was a crocodile-like creature that was as long as a school bus and heavy as 2 elephants.  It weighed as much as 13 big polar bears.  Sarcosuchus had slender jaws compared to Deinosuchus, but was still capable of subduing large prey items.  For a size comparison, this matchup would be like a sun bear taking on a Nile crocodile.  Polar bears are very strong & durable, but don't possess the level of weaponry (or the size) to effect Sarcosuchus adversely.  Sarcosuchus would only need to catch the polar bear in its jaws to gain control of the fight.  Sarcosuchus wins.

5. Smilodon vs. Sarcosuchus: Sarcosuchus weighed over 20 times as much as Smilodon populator.  Smilodon was a powerful, stocky, muscular felid with the ability to wrestle large prey items to the ground and finish them with a stab of its long upper canines.  Sarcosuchus was armored like today's crocodiles, and penetration by the cat's sabers in a vulnerable spot would have been a longshot at best.  Smilodon would not have the strength or size to hold the huge "SuperCroc" in place to secure a good position.  Imagine a clouded leopard trying to subdue an American alligator!  To win a battle on land would be extremely improbable for Smilodon, and a win in the water would be next to impossible.  Sarcosuchus wins.

6. Arctotherium vs. Deinosuchus: Arctotherium (South American giant short-faced bear) is related to the Spectacled bear, but is over twice as tall at the shoulder and 9 times as heavy.  Deinosuchus was a huge alligator-like reptile that was twice as long as any modern crocodile & over 8 times as heavy.  Arctotherium would have no chance in the water against Deinosuchus, and a small chance on land.  With Deinosuchus weighing 5 times as much as Arctotherium (and having a similar shoulder height when walking), it would only need to catch the bear in its jaws to gain control of the fight.  Arctotherium would have superior stamina & mobility, but would have no reasonable way to injure the huge reptile (would not have the strength to control positioning & would not have effective enough weaponry to breach the armored hide).  This would be similar to an Asiatic black bear taking on a saltwater crocodile.  Deinosuchus wins.

7. Ceratosaurus vs. Polar Bear: Ceratosaurus weighs about 25% more than a big polar bear.  Ceratosaurus was a theropod with a large skull and jaws filled with teeth, and its bite would be a mighty weapon against a polar bear.  The polar bear is a great fighter (good endurance & durability, jaws & claws, use of forelimbs to grab/control), but isn't practiced at tackling mobile opponents with a decent size advantage.  The bear would not be able to topple Ceratosaurus without receiving several nasty bites.  Ceratosaurus wins.

8. Kodiak Bear vs. Saltwater Crocodile (in 4 feet of water): The saltwater crocodile will weigh close to 50% more than the Kodiak bear, and occasionally even more.  Kodiak bears are durable, strong mammals with good weaponry (jaws & claws).  Crocodiles have extremely powerful jaws that close with a great deal of force, and they use this to seize prey items securely to be pulled into the water & drowned.  The lack of mobility & stamina that a crocodile experiences on land won't be a hindrance in 4ft of water, and it will be able to make powerful movements in this location.  A Kodiak bear would be favored against a saltwater crocodile on land more times than not, but it will have trouble against one in water this deep.  The Kodiak's weaponry won't be as effective in the water as it will be on land, and once the crocodile clamps on with its jaws, it will not likely have the strength to prevent the crocodile from applying torque (spinning force).  The Kodiak bear is about 5' at the shoulder, so it can fight with its head above water, but it won't be as comfortable in this setting as the crocodile will.  Crocodiles can grab & manipulate animals at the water's edge that weigh close to their own weight, and the bear can certainly fall into that category.  Saltwater crocodile wins.

9. Spinosaurus vs. Great White (in 10 feet of water): Spinosaurus will weigh over 3 1/2 times more than the great white shark.  Spinosaurus is used to operating in water this deep, and has jaws & teeth fashioned to grab scaly prey items.  The shark will have little room to move vertically (which is an asset in ambush), and its lateral movements will be easier to predict with that limitation.  The shark's bite (jaws with many rows of razor-sharp teeth) can certainly injure a Spinosaurus, but it won't have many good opportunities to deliver it.  Spinosaurus won't be able to kill the great white shark with a single bite, but will be able to hold it in place with its jaws, and cause some damage to the less-robust areas on the fish's body.  Edge to Spinosaurus.

10. Harpy Eagle vs. Komodo Dragon: The Komodo dragon will weigh anywhere from 7 1/2 to 10 times as much as the harpy eagle, but the weight difference isn't the most important factor in this conflict.  The harpy eagle is a strong bird with strong, sharp talons & a powerful beak.  It can predate upon animals close to its own weight (and sometimes heavier).  Komodo dragons have a dangerous bite (sharp teeth, bacteria, toxin), sharp claws, and a whip-like tail.  These giant lizards also have tough hides (with small osteoderms) that provide protection against many attacks (including intraspecies squabbles).  The harpy eagle's talons would likely cause damage to the komodo's tough hide, but not as much as they would against an unprotected target (like a monkey).  The harpy would probably succeed in driving the Komodo dragon away if it wanted to, but killing it would be another matter.  The komodo is capable of short bursts of speed, and could catch the bird in its jaws if it anticipated its attack.  The head of the Komodo dragon would be the most vulnerable place for the eagle to attack, but it would also be the most treacherous (as it would place the bird close to the deadly jaws).  The harpy eagle is capable of winning with a precise strike, but it probably won't succeed on most occasions against this huge lizard.  Edge to Komodo dragon.

11. Wolverine vs. Golden Eagle: The wolverine will weigh 3 times as much as the golden eagle.  It's hard to make this a fair fight (raptor vs land animal) due to the ways it can occur.  The eagle could ambush the wolverine, the eagle could attack the wolverine with the wolverine being aware of its presence, or the fight could start with the bird on the ground (which would not end well for it).  Wolverines have thick fur & durable hides, and an eagle's talon strike would need to be precise for it to overcome the mammal.  An ambush would give the golden eagle a small chance to target the head or the spine, but there's no guarantee the wolverine would be overpowered by this every time.  Any strike by the golden eagle that didn't land perfectly would result in the wolverine turning the tables immediately and mauling the comparatively fragile bird.  The chances of the eagle succeeding (regardless of attack method) aren't very good.  Wolverine wins.  

12. Baboon vs. Komodo Dragon: The Komodo dragon will weigh approximately twice as much as the largest of baboons (mandrills, drills, chacmas, olives).  Komodo dragons have a dangerous bite (sharp teeth, bacteria, toxin), sharp claws, and a whip-like tail.  These giant lizards also have tough hides (with small osteoderms) that provide protection against many attacks (including intraspecies squabbles).  Baboons are agile primates with good leaping ability & impressive weaponry (grabbing hands, 2" upper canines).  A baboon's bite wouldn't easily penetrate a Komodo dragon's hide, and the attempt would leave the monkey vulnerable to a deadly bite from the reptile (which can make short, quick movements).  The baboon would also be in danger of a tail strike, and would not be able to subdue the komodo without a decent accumulation of bites.  Komodo dragon wins.

13. Wolverine vs. Bonobo: The wolverine will be about 1/2 the bonobo's weight.  Wolverines are among the strongest mammals pound-for-pound, and are well-armed with strong jaws (can crunch through frozen meat & bone) & sharp claws (perfect for digging).  They are notoriously aggressive & combative, and have driven bears & wolves away from their kills.  Bonobo chimps aren't as large as common chimps, and are usually less than 2/3 the size.  They aren't as formidable (pound-for-pound) as their larger cousins, but are still strong primates with grabbing hands & decent bites.  Even with a size advantage, a bonobo will have trouble dealing with the ferocious wolverine, and will likely be driven away by the battle-tested mustelid.  Edge to wolverine.  

14. Chimpanzee vs. Mountain Goat: A mountain goat can weigh over twice as much as a chimpanzee.  Mountain goats are hardy animals with sharp horns, and they defend themselves well from predators.  Chimpanzees are strong primates that can deliver nasty bites, but are not practiced at taking on larger animals.  They usually gang up on adversaries, and larger ones are simply chased away or intimidated into a retreat.  A single chimpanzee won't have a clue as to how to proceed against a mountain goat, and the goat will trample the ape or gore it with its horns.  Mountain goat wins.

15. Moose vs. Spanish Bull: These animals will weigh about the same.  Moose are the largest cervids, and have wide-spreading antlers with sharp points on the edges.  These antlers can be used as a shield or a ramming weapon.  Spanish fighting bulls are muscular bovids with forward-pointing horns that can be driven into an opponent with a lot of force.  These bulls are capable of making powerful, violent movements.  The aggression level will be higher in the bull than in the moose, and the bovid's weaponry can be used more effectively.  Moose can be capable combatants (defending against bears & wolves), but the stronger Spanish fighting bull is on another level.  Spanish fighting bull wins.

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.
