Hello Jem.

1. Olive baboon vs African hunting dog: The African hunting dog will be about 90% of the olive baboon's weight.  African wild dogs are pack animals, and typically engage in any conflict as a team.  They have strong bites (used to grab onto large prey items to help pull them to the ground), and great lateral movement (side-to-side; front-to-back).  Olive baboons are robust primates with dog-like muzzles and sharp upper canines as long as matchsticks.  Olive baboons have good mobility (not as quick as the African wild dog overall) and are actually good leapers.  Their fearsome teeth can be used to cause serious, deep wounds in an attacker (as evidenced by gruesome wounds left on dogs & other animals that have fought baboons).  The African wild dog will likely try to latch onto the olive baboon with its jaws in an attempt to induce blood loss or employ a "bite & retreat" method.  The baboon's mobility & use of its hands will keep the African wild dog from achieving accuracy with its biting attack, and the counter-offense by the primate will likely find its mark when the canid comes into range.  Both animals will have equal chances to land bites, but the olive baboon's bites will prove to be more effective before too much time passes.  African wild dogs typically give baboons a wide berth, and for good reason.  Olive baboon wins.

2. Goliath Tigerfish vs Giant otter: A giant otter will be close to the weight of the goliath tigerfish, but will be slightly lighter at maximum weights.  Otters have great mobility in the water, and this will be its biggest advantage.  The tigerfish has fearsome jaws with long, pointed teeth that can cause a lot of damage to an otter, but catching it will be another matter.  The bite of an otter won't have as much effect on the tigerfish (scales) as the tigerfish's bite will have on the otter, but the mustelid will likely land many bites before it gets bitten itself.  The otter will be in the most danger when it tries to land a bite on the tigerfish (because that's the fish's best chance to counter).  The tigerfish is capable of quick movements in the water, and the giant otter will need to attack the rear of this fish to avoid the jaws.  Could go either way; slightest of edges to the giant otter at equal weights; advantage to the goliath tigerfish with any weight advantage.

3. Sumatran Tiger vs Jaguar: These animals will be close in weight, but a big jaguar can outweigh the tiger by over 10%.  Both cats have the typical felid assets (speed, agility, jaws & claws, killing know-how), but have different builds & different preferred finishing techniques.  The jaguar will be slightly stronger than the tiger (jaguars are generally considered to be the strongest felids pound-for-pound), and will have a stockier build with shorter legs.  Jaguars are the reptile-killing experts of the big cat world, and typically dispatch them & other prey items with a powerful bite to the skull (or back of the neck).  The bite force of a jaguar is the strongest among big cats in proportion to its size, and the jaws can crush turtle shells & penetrate caiman armor.  Sumatran tigers typically kill with a throat bite (as with most big cats).  A "swipe war" would likely favor the tiger (will be slightly faster & have a reach advantage), but a physical battle for positioning will likely favor the jaguar.  The jaguar's unique (and more diversified) finishing method will be easier to employ than the tiger's throat bite (which has a more specified target area), and its slight weight advantage will aid in in this battle as well.  Edge to jaguar.  

4. Sumatran Tiger vs Spectacled bear: The Sumatran tiger will weigh about 80% of the spectacled bear's weight.  Spectacled bears are among the most herbivorous of bears (but have taken livestock at times) and are not as formidable (pound-for-pound) as brown bears.  However, they share the same ursid assets (strength, endurance, durability, paw usage), and can be capable combatants with their jaws & claws.  Sumatran tigers are great hunters & fighters (as all tigers are), and will have several advantages over the bear (speed, agility, finishing know-how).  A realistic encounter would likely have the spectacled bear driving the tiger away, but a determined tiger will be a serious match for it.  The tiger will try to use its agility (and forelimbs/claws) to obtain a favorable position from which to secure a throat-bite, and the bear will swipe, grab, & bite in an effort to prevent this (and repel the tiger).  Even though the spectacled bear will pose a different set of challenges, the Sumatran tiger will attempt to treat it as a typical prey item (tapir, wild boar, deer, etc.) when going for the kill.  This battle can go either way, but a fight to the finish will slightly favor the more predatory tiger (unless it is a prolonged battle).  Slight edge to Sumatran tiger.

5. Jaguar vs Spectacled bear: The jaguar will weigh about 90% of the spectacled bear's weight.  This will be similar to the Sumatran tiger vs spectacled bear matchup, but the jaguar will be closer to the bear in size.  The more diversified attack employed by the jaguar (skull or spine bite) will come in handy as it wrestles with the spectacled bear, and the felid will have a decent chance to complete the kill before it fatigues.  As with the tiger, the bear will likely drive the jaguar away in a realistic encounter.  Edge to jaguar.

6. Spotted Hyena vs Sloth bear: The sloth bear will weigh over 2 1/2 times more than a big spotted hyena.  Spotted hyenas are durable animals with extremely strong bites, but they are somewhat ungainly & don't have the same level of lateral movement as, let's say, a wolf or a wild dog.  Spotted hyenas typically engage in a conflict as a group, but can be dangerous solo as well.  Sloth bears aren't the most robust of bears, but they are still capable fighters (with jaws & claws) and have a lot of strength & endurance.  Their use of paws (to swipe/grab/control) is a huge asset in a conflict.  In this particular matchup, the sloth bear will dominate the spotted hyena.  The hyena will put itself in serious danger when it approaches to bite, and the sloth bear will overpower it rather easily when its forelimbs make contact.  It may take the sloth bear a while to actually finish off the durable hyena, but it will be in control until it does.  The sun bear is much smaller than the sloth bear, but has similar attributes, and would be a much better matchup for the spotted hyena.  A sun bear is nearly the weight of a big spotted hyena, and would have a slight edge over one.  In this matchup, however, the sloth bear wins.

7. Pitbull vs Bull terrier: Bull terriers are slightly heavier than American pitbull terriers.  Bull terriers have egg-shaped heads, very strong jaws, & high levels of endurance & tenacity.  They are used in dog breeding to infuse these qualities into a larger, more powerful body to produce a more formidable dog.  American pitbull terriers have bull terrier in them (and all of their qualities), and are stronger nose-to-tail.  A bull terrier can certainly be a fierce combatant in its own right, but the American pitbull terrier is a cut above.  APBTs are muscular & athletic, and game ones will battle ferociously until they drop.  Both of these dogs will rush in immediately and latch on with their jaws (and will typically employ the "bite & shake" method), but the more powerful APBT will be more in control.  Pitbull wins.

8. Pitbull vs Fossa: The American pitbull terrier weighs over twice as much as a fossa.  An APBT is the supreme combatant (pound-for-pound) of the canine world, and is a serious adversary for anything in its weight range.  They have strength, athleticism, endurance, durability, tenacity, & strong jaws that make them very formidable.  Fossas are very impressive animals as well.  They are the top predator of Madagascar (feeding mainly on lemurs, but will take domesticated pigs & poultry), and have the appearance of a small cougar.  Fossas have slender, muscular bodies, and are very good leapers & climbers (sharp, retractable claws).  This agile predator has a round head & short, powerful jaws.  Fossas can be capable fighters, but one would be in trouble against a pitbull over twice its weight.  Fossas don't have to deal with similar-sized predators in Madagascar, and would probably find a charging APBT to be a bit overwhelming.  The Staffordshire bull terrier (a smaller version of an APBT, sort of, with similar attributes) would be closer to the fossa's weight range, but would still be a stiff challenge for it.  Pitbull wins.

9. Fossa vs Ocelot: The ocelot will weigh at almost 15% more than the fossa.  Both of these animals have similar attributes (agility, climbing & leaping ability, strong jaws & teeth, sharp claws) and similar builds.  A battle between these 2 would likely be similar to 2 alley cats fighting (ferocious biting & clawing).  The jaws of the fossa are comparable to the ocelot's, but its teeth are slightly shorter.  Close fight at parity, but the ocelot's weight advantage will likely make a difference.  Slight edge to the ocelot.

10. Main event: Great white shark vs Greenland Shark: Greenland sharks can approach the weight of a typical great white shark, but only the whale shark is heavier at maximum weights.  The great white shark is the king of the predatory sharks, and will have a decisive size & speed advantage over the Greenland shark (which is a slow swimmer).  The great white shark will land the first bite with few exceptions, and should dominate this encounter.  Great white shark 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.
