Hello Jem.

1. Gull terr vs Presa Canario: The Presa Canario will weigh at least 30% more than the largest Gull Terr.  Gull Terrs are skilled and relentless in combat, and have plenty of energy.  They are also nimble, and have robust skulls that enable their jaws to deliver powerful bites.  Presa Canarios are strong, muscular, confident dogs that have massive, square heads and large jaws.  The anterior half of their bodies are especially robust.  Presa Canarios have been used as guardians and for driving cattle (as well as fighting).  Although usually docile, Presas can be powerful and skilled combatants.  The weight advantage of the Presa Canario will enable it to control the positioning better once the 2 make contact, and it will likely land the bigger bites.  Very close at parity, but not at absolute weights.  Presa Canario wins.

2. Presa Canario vs Central Asian Ovtcharka: The Central Asian Ovcharka will weigh slightly more than the Presa Canario.  Presa Canarios are among the top canine combatants at absolute weights, and they have very good stamina.  Central Asian Ovcharkas are furry dogs with great physical strength, and they have been used as livestock guardians (defending against wolves and bears).  The Central Asian Ovcharka's stamina is as impressive as the Presa Canario's, but its agility is likely a bit less (although good for its size).  Using the best representation of each animal, the Presa Canario will have the edge.  Edge to Presa Canario.   

3. I wanted to ask you that my most favorite competitor is the leopard, what is yours?:  I have a few favorites.  The leopard is perhaps the most asked-about animal on this site, and it and other big cats are high on the list.  Bears, wolverines, and honey badgers are up there as well.  One prehistoric animal that can be utilized in a number of unique, interesting matchups is the Quetzalcoatlus.  It is very light for its size, but its weaponry can make it a hard puzzle to solve for many opponents that weigh much more than it does.  Other favorite prehistoric choices include Smilodon populator, Megalictis ferox, and Triceratops.  There's a few modern reptiles (anaconda, Komodo dragon, etc.) and a few prehistoric ones (Deinosuchus, Titanoboa, etc.) that make good competitors and interesting matchups.  If I had to make a single choice, I would probably go with the wolverine.

4. Leopard vs Cave Hyena: The cave hyena will have a small weight advantage over the African leopard.  The cave hyena was durable, had a tremendous bite force, and formed clans to tackle very large prey items.  Leopards are among the strongest cats pound-for-pound, and have large heads and well-developed shoulder & neck muscles.  They can haul heavy prey items into trees by seizing the animal tightly in their jaws and climbing strongly with their claws gripping into the tree.  They are superb hunters with great finishing ability, and can tackle prey items much larger than themselves.  Leopards are also battle-tested, as they commonly engage in confrontations with a variety of dangerous animals (hyenas, baboons, etc.).  Even though the leopard has more versatile weaponry (jaws and claws) than the cave hyena (jaws) and possesses greater speed and agility, it will not risk injury in a confrontation that might interfere with its ability to hunt.  The leopard will be able to win this if it fights to the bitter end, but that won't realistically happen.  Any realistic confrontation will result in the cave hyena driving the leopard away.  Edge to leopard in fight to the death; edge to cave hyena in realistic encounter.

5. White Rhinoceros vs African Elephant: An African elephant can weight at least 50% more than a maximum-sized white rhinoceros.  White rhinos are massively powerful animals with very tough hides and a tank-like build.  They have 2 nose horns, and the longer one in front can be used to gore adversaries with.  The African elephant is the largest land animal.  It is extremely strong, can be quite aggressive, and has a muscular trunk and long sharp tusks.  The elephant can use its weight to push with a great deal of force or crush a smaller animal.  Its tusks can be used to stab, and it has been known to kill rhinos.  The African elephant is the most formidable land animal living today, and only another elephant can seriously challenge it one-on-one.  The white rhino is probably the only other land animal that would have any real chance in a battle with an elephant.  I would favor a white rhino at parity (its weapon can be used with greater ease and reach; its hide is tougher), but not against a pachyderm exceeding 6 tons.  African elephant wins.

6. Leopard Seal vs Anaconda: The leopard seal will weigh 2 to almost 3 times as much as the anaconda.  The leopard seal is an active predator with large teeth (some up to 2.5cm long).  It primarily feeds on penguins, but will predate upon other aquatic animals (including smaller seals).  The green anaconda is the world's heaviest snake (sometimes exceeding 180kg).  It is a superb ambush hunter, and kills captured animals by asphyxiating them in its powerful coils.  The anaconda isn't a great face-to-face fighter on land (limited mobility and stamina), but its prowess in the water is much greater.  The leopard seal's bulk will keep it from being constricted easily, and its bite can damage the anaconda's body.  On land the anaconda will back down (it won't have any real options), and in the water the leopard seal's mobility will actually be greater.  The movements needed for the leopard seal to effectively bite the anaconda will come easier that the ones needed by the anaconda to use its coils effectively.  The seal will be too big, and the snake will be comparatively too slow in the water.  Leopard seal wins.

7. Gorilla vs Cave Hyena: A large wild gorilla can weigh up to 208kg, which is a little more than twice a cave hyena's weight.  Gorillas aren't experienced at fighting other types of animals (they usually try to "bluff" as opposed to physically engaging), but they possess attributes that make them dangerous adversaries if they are forced to defend themselves.  A gorilla is very strong, its arms can span over 2.5m, and its grabbing hands can help it to dictate positioning in a fight.  Its bite can cause nasty wounds due to its high bite force and 5cm canines.  A gorilla primarily tries to pull & bite in a serious confrontation, but its flailing arms can strike with some effect as well.  The cave hyena is somewhat like a larger version of a spotted hyena, and has the same traits (toughness, endurance, bone-crushing bite) as one.  A cave hyena won't have a good chance to overcome a gorilla without help, and will likely be driven away by the gorilla's displays of aggression (which, despite the ape's peaceful nature, will occur if it feels threatened).  Gorilla wins.  

8. Gorilla vs Spotted Hyena: The gorilla will weigh about 3 times as much as the spotted hyena.  The gorilla will certainly be able to deter the spotted hyena with an aggressive display (hyenas aren't as confident without help from their clan), and will be large enough to defend itself if the hyena unwisely decides to attack.  The strong arms and grabbing hands of the gorilla will easily control the positioning of the battle at close quarters where the primate can utilize its bite (high bite force and 5cm canines).  Spotted hyenas have great durability, endurance, and very strong bites, but one will be outmatched here by this huge ape.  A chimpanzee is a better matchup for a spotted hyena.  Gorilla wins.

9. Pacific Giant Octopus vs Leopard Seal: A leopard seal can weigh approximately 5-6 times more than a giant Pacific octopus.  This octopus can weigh almost as much as a human male and have an arm span well over 4m.  An octopus has a soft, supple body and 8 tentacles that can wrap around another animal to impede its movements.  It can bite with its hard beak as well.  A leopard seal will have a large size and mobility advantage over the octopus, and that will be key.  The leopard seal's formidable jaws can do a lot of damage to the body of the octopus, and the mammal will be maneuverable enough to keep from getting "wrapped up".  Even if the octopus wraps its tentacles around the larger animal, it won't be able to consistently control the seal's movements or advance its own offense with any great effect.  It's tough to deal with an animal with tentacles, but the seal has too much size here.  Leopard seal wins.

10. Hippopotamus vs Polar Bear: The hippo can weigh 3-4 times as much as the polar bear, and will be about the same height at the shoulder.  A hippo has a large barrel-shaped body and a huge set of jaws (long sharp-edged canines for slashing and biting; forward-pointing incisors for thrusting).  A polar bear is very powerful animal with strong jaws and huge paws (for swiping, clawing, gripping, etc.), and it sometimes battles walruses on land.  A polar bear doesn't deal with any mobile land animals with a great size advantage, and one won't have the strength to manipulate the movements of a 2,700kg animal in a close-quarters battle.  A polar bear has many attributes that make it a skillful fighter, but its lack of adequate lateral quickness will be problematic for it against a charging hippo.  Simply put, the polar bear won't be quick enough to get out of the way, and the hippo's bite will cause serious injury to it.  Hippopotamus wins.  

11. Kodiak brown bear vs Hippopotamus: The hippo can weigh 3-4 times as much as the Kodiak bear, and will be about the same height at the shoulder.  Kodiak bears are powerful fighters, but don't have the size to take on a hippopotamus.  Hippos have jaws that can open almost 4ft wide, and are armed with sharp lower canines that can cause massive damage to a bear.  The Kodiak bear can injure the hippo with paw swipes, but it would take a lot of them to have great effect.  The bear doesn't have the lateral quickness to avoid getting bit by the hippo's jaws (which would be key), and doesn't have the leaping ability (like a big cat) to jump on top of the hippo.  Brown bears can usually handle most animals close to their weight range, but the larger hippo will be too formidable for it.  Hippopotamus wins.

12. Tiger Shark vs Leopard Seal: The tiger shark will weigh at least 40% more than the leopard seal (and close to twice as heavy on occasion).  The leopard seal will have a mobility advantage, and can avoid the tiger shark's attack by swimming around it and staying out of range.  Seals can out-maneuver sharks, but they can't swim faster in one direction.  In order for the leopard seal to subdue the shark, it will have to attack it with many bites over a period of time (which won't be easy because sharks have tough scales that make breaching the hide difficult).  This will put the seal in danger of getting bit (the shark can make short, quick movements).  Tiger shark wins.

13. Saltwater croc vs Leopard Seal: A saltwater crocodile can weigh 2 to almost 3 times as much as a leopard seal.  A saltwater crocodile is a huge reptile with armor-like hide and tremendously strong jaws.  It will attack animals at the water's edge, but will also attack aquatic animals.  A leopard seal is a feared predator for many creatures (chiefly penguins) off the coast of Antarctica, and its teeth can measure 2.5cm long.  It has great mobility in the water.  A leopard seal can potentially injure a crocodile twice its own weight with an accumulation of bites, but keeping up such an attack can put it in danger of the crocodile's jaws (although its mobility won't be nearly as good as the seal's, it can make quick turns with its head).  Many areas of the crocodile's hide will be too tough for the leopard seal to breach, but some areas may be vulnerable.  The leopard seal's maneuverability will be its best asset, and the crocodile's jaws and armor will be its best assets.  Although a stalemate may occur (neither animal being able to complete a kill), the leopard seal should have the edge in deep water, and the crocodile will probably gain the advantage in shallow water.  A maximum-sized saltwater crocodile (close to 3 times the seal's weight) will probably be favored in any location due to its ability to end the fight quickly if it can clamp its jaws onto the seal at some point.  Close battle; depends on the size of the competitors.   

14. Bull shark vs Pacific giant octopus: A bull shark can weigh at least 3 times as much as a giant Pacific octopus.  A bull shark has tough hide and very sharp teeth.  It can be quite aggressive and unpredictable, and has attacked people.  The bull shark usually swims slowly, but can move very quickly when the situation calls for it.  They primarily eat fish, but will also eat dolphins, turtles, and a variety of other animals they come across.  The giant Pacific octopus is capable of killing small sharks, but a bull shark is probably too large for it to conquer.  Although the octopus can probably impede the movement of the bull shark by wrapping its tentacles around it, it's unlikely a kill will be made without some unusual circumstances occurring (gills covered up, for example).  The bull shark's bite can easily slice the body of the octopus, and realistically the cephalopod will avoid this encounter.  Having tentacles can be a valuable asset in combat and I would favor the octopus at parity, but not at these weights.  Edge to bull shark.  

15. Black Rhinoceros vs Hippopotamus: A big river hippopotamus can weigh almost twice as much as a black rhinoceros, but its shoulder height will be a bit less, and it will have problems defeating one.  The black rhino is the most aggressive of all rhinos, and its tank-like body and very tough hide make it a formidable adversary.  On land the black rhino will be more comfortable than the hippo, and will be able to make strong attacks with the longer of its 2 nose horns.  The hippo has wide-opening jaws with long, sharp canines to bite with and forward-pointing incisors to thrust with, but it will not be able to land a bite easily without getting stabbed by the black rhino.  In water the hippo will be more territorial and aggressive, but it won't gain enough of an advantage in lateral movement to consistently avoid getting stabbed.  Both animals have the means to seriously injure one another, but the black rhino's ability to more effectively utilize its weapon (and its edge in durability) gives it a slight advantage over the larger animal.  Edge to black rhinoceros.

16. Main event: Wild Boar vs Spotted Hyena: A wild boar can weigh over 200kg, which is almost 3 times as much as a spotted hyena (70kg; on occasion 80kg).  Large Russian wild boars can reportedly approach 350kg, but that's probably not typical.  Wild boars are aggressive at times, and their sharp tusks and tough hides make them formidable adversaries and risky prey targets.  A wild boar has very good lateral quickness, so it can charge and turn quickly to utilize its tusks offensively.  The spotted hyena is a battle-tested animal (occasional conflicts with lions, leopards, African wild dogs, etc.), and is famous for its bone-crushing bite.  The spotted hyena is also very durable and has solid stamina.  However, it typically hunts and fights with help from its clan, and its somewhat clumsy movements will make it less likely to avoid the tusks of a wild boar than, let's say, a gray wolf.  A parity fight will be reasonably close (slight edge to the boar), but no single spotted hyena will have much of a chance against a wild boar that weighs almost triple its own weight.  Wild boar wins.

Good matchups as always!

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.
