Interspecies Conflict/question


Hello BK,

Thank you for your good and fast answers.
Here are some questions:

Male Grizzly Bear 650KG VS 4 Lionness 150KG each.

Male Chimpanzee 60KG VS Female Spotted Hyena 70KG.

Male Black Bear 300KG VS Male Lion 250KG.

Asian Black Bear 150 VS Male Lion 250KG.

Male Gorilla 90KG VS Male Leopard 65KG.

2 Female Hyenas each 75KG defending there cubes VS Male Lion 200KG.

Is there a type of dog with a weight advantage that is capable of Defeating a Female Hyena of 75KG?

Thanks for your answers.


Hello again Henk.

Male Grizzly bear (650kg) vs 4 Lionesses (150kg each): Grizzly bears are probably the most formidable bear pound-for-pound, and is perhaps the most aggressive.  This powerful animal has a well-defined shoulder hump that houses huge muscles that enable it to swipe with tremendous force.  A grizzly bear's bite is very strong, and its 4" claws (well-suited for digging into tough ground) can be wielded as dangerous weapons.  Bears have phenomenal endurance, and will battle fiercely even after sustaining injury.  This bear will be about 50% taller at the shoulder than each lioness.  Lionesses are the master group hunters of the big cat world, and use their teamwork to bring down animals much larger than themselves (Cape buffalo, eland, zebra, etc.).  Lionesses are quick & agile, and can employ their weapons (jaws & claws) with great skill.  Most large animals on the lionesses' menu have limited ways to fight back once the cats swarm onto them, but a grizzly bear has greater flexibility & more diversified weaponry than most herbivores.  The grizzly will have the power to seriously injure a lioness with a well-placed paw swipe (or by controlling the cat with its paws while it delivers a bite), and it will have the stamina to continue to turn & counter-attack for a long time if attacked by 4 of them.  The lionesses will need to attack from different sides in an attempt to divert & dilute the bear's offense, and will need to secure a throat bite at some point if they hope to overcome the ursid.  Lionesses will sometimes take turns attacking to give themselves a breather when attacking large prey (for example: 2 will attack while the other 2 rest, then they switch positions), but they would be ill-advised to attempt this with a bear of this size & might (because the bear could quickly gain the upper hand against 2 or 3 lionesses).  The lionesses can pull this off if they are careful to avoid injury & stick to a well-executed game plan, but the chances of this occurring aren't great.  The bear will likely reduce the number of effective attackers before too much time passes, and will have the stamina to battle until the lionesses lose interest or lose enough members to injury to remove the numbers advantage.  1 or 2 more lionesses would be needed to give the cats a decent chance at victory over this huge grizzly bear.  Grizzly bear wins.

Male Chimpanzee (60kg) vs Female Spotted hyena (70kg): Chimpanzees are strong primates, and can be aggressive at times, but usually employ a defensive display to intimidate rivals as opposed to physically engaging them.  They have good mobility, use of their hands, & a dangerous bite to serve them in a conflict.  Spotted hyenas are durable animals with bone-crushing bites, and they are used to physical confrontations with a variety of formidable opponents (lions, leopards, African hunting dogs, etc.).  Chimpanzees don't have the ability to easily dispatch another large animal solo, but a spotted hyena does.  The chimpanzee's assault on the hyena would have minimal effect in the small window of time it would have before the hyena's powerful jaws latched on.  A chimpanzee would need a weight advantage to compete with a spotted hyena, and it doesn't have it here.  Female spotted hyena wins.

Male Black bear (300kg) vs Male Lion (250kg): The lion will be slightly taller at the shoulder than the black bear at these weights.  Black bears aren't as formidable pound-for-pound as brown bears (or as confrontational), but they are still dangerous to any adversary.  They have great strength, good weaponry (jaws & paws), and fantastic endurance.  Black bears are omnivores (only 5% of its diet consists of meat), and don't typically tackle large animals in their habitats.  Male lions are the fighters of the big cat world, and routinely battle other lions to defend their prides from takeover.  Lions don't encounter bears in the wild, but deal with a variety of dangerous animals on a regular basis.  Lions are quick & agile, and have sharp claws & the ability to finish kills with a throat bite.  The bear's paws are armed with short, sharp claws (ideal for digging & tree climbing) that can cause a lot of damage with a swiping attack.  The black bear will attempt to fend off the lion by striking/grabbing with its paws & biting, and the quicker lion will try to use its claws to hook into the bear to help maneuver it into position to land a finishing bite.  The lion will have a decent chance to get into a favorable position before it tires out, but this won't occur every time.  Slight edge to male lion.

Asian Black bear (150kg) vs Male Lion (250kg): Asiatic black bears aren't as robustly built as some of the larger bears, but still have some of the attributes associated with them (strength, endurance, etc.).  Asiatic black bears occasionally encounter tigers in their range, and sometimes have success in driving these formidable cats away (tigers are almost exclusively solo hunters & will usually avoid getting injured unless conflict is necessary).  The Asiatic black bear's exposure to tigers will aid it somewhat in a battle with a lion (which never encounters bears), but it will be in trouble against one at these weights.  Lions are accustomed to combat (with other lions & a variety of other dangerous animals), and will use its speed & length to control the positioning of this battle (and finish with a throat bite) on most occasions.  Male lion wins.

Male Gorilla (90kg) vs Male leopard (65kg): Leopards sometimes predate on gorillas, but it is mostly by ambush.  A large gorilla can drive a leopard away if it's aware of the cat's presence.  A male gorilla weighing 90kg might be a sub-adult (they can exceed 200kg), but we'll assume it's an adult for purposes of this matchup.  Gorillas aren't used to engaging other animals face-to-face (except other gorillas), and usually try to intimidate before attacking.  Gorillas are very strong, and have powerful arms with grabbing hands.  Their bite is dangerous as well.  Leopards are accomplished predators, and routinely deal with formidable adversaries (hyenas, baboons, etc.) as well as tackling large prey items (antelopes, suids, etc.).  In a face-to-face with a gorilla, the leopard will have the advantage in speed, quickness, killing know-how, & weaponry (jaws & claws).  The leopard will likely attempt to engage the gorilla with its front paws, slide on its back, and use its back claws to rip into the primate.  When an opportunity presents itself, the leopard will try to secure a throat bite.  The gorilla will be stronger than the leopard at these weights, and will have a chance to overpower the cat at close quarters in the initial stages of the battle.  However, the primate won't have an answer for the leopard's claws on most occasions (as they can easily shred the hide of the ape).  In a realistic encounter, a gorilla with this weight advantage will probably drive the leopard away, but an actual fight with determined individuals will favor the well-armed/battle-tested leopard more times than not.  Male leopard wins.

2 Female Hyenas defending cubs (75kg) vs Male Lion (200kg): Spotted hyenas (the only ones that can attain this weight) are the most powerfully built of all the hyenas, and have a high level of endurance & durability.  Their jaws can easily crush bone, and they work well as a team.  However, a male lion of this size will dominate these hyenas on most occasions.  Lions are ferocious combatants, and can use their paws (with sharp claws) to control positioning & slash with.  The hyenas in this scenario would abandon the scene at the arrival of a male lion, but would be in serious danger if they stood their ground.  The lion might receive a painful bite or two, but will impose its will in short order.  4 female spotted hyenas (at 75kg each) would likely be needed to drive a male lion (at 200kg) away.  Male lion wins.

Q: Is there a type of dog with a weight advantage that is capable of defeating a female hyena of 75kg?
A: No domestic dog will defeat a determined 75kg spotted hyena on most occasions, but a few could succeed in driving it away (and perhaps win on rare occasions).  Gull Dongs, Tosas, Bully Kuttas, Caucasian Ovcharkas, Presa Canarios, & a few others have the combination of size & ability to give the hyena a run for its money, but even these breeds will be outmatched by its toughness & powerful bite.  Domestic dogs will have an advantage in agility (and in some cases ferocity if the dog is trained), but a close-quarters conflict with a spotted hyena will be a bite vs bite affair (which the hyena will win).  If one of these formidable dog breeds used its better lateral movement to secure a neck bite on the hyena where the hyena couldn't bite back, the dog might have a chance.  However, the battle-tested hyena will have too much experience to allow this to easily occur.  A grey wolf exceeding 90kg would probably give a 75kg spotted hyena a fair fight, and no domestic dog on the planet would be favored against a 90kg grey wolf.  Some domestic dog breeds can get much heavier than the hyena (English Mastiff, Saint Bernard, etc.), but don't have the fighting ability to compete with this wild animal.  Other dog breeds that have a high level of combat ability (Kangals, Boerboels, American Bulldogs, American Pitbull Terriers, etc.) don't have the size to compete with the hyena.  I would probably favor a 70kg spotted hyena against any domestic dog on most occasions.  

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.
