Thank You

Hello Trish.  Been doing good overall.  Glad everything is great with you.

Nile Crocodile vs Moose: A typical Nile crocodile will weigh a bit less than a large moose, but a big one can weigh over 25% more.  The Nile crocodile is covered in osteoderms that provide an armor-like barrier against attack, and is armed with huge jaws that can close with tremendous force.  The crocodiles' bite isn't typically the killing mechanism that dispatches prey, but it can hold the victim in place while the reptile drags it into deep water to drown (drowning is its most common killing method).  The crocodile's teeth act as cleats to grip and hold, and its body can spin in the water with a great deal of torque to rip away chunks of flesh.  A crocodile doesn't have a great deal of mobility on land (it can make short, quick movements), and its endurance isn't typically very good (although some attempts to capture crocodiles lead to the reptiles fighting strongly for substantial lengths of time).  A moose is the largest, most powerful member of the deer family.  It can weigh over 1,600lbs and can run and jump rather well.  A moose will defend itself from predators (like bears and wolves) by kicking with its sharp hooves or driving forward with its massive antlers.  A moose will likely be a good match for a Nile crocodile on land in most encounters due to its superior mobility, but it won't be able to easily injure the reptile without putting itself in harm's way.  A moose might be able to pull away from a crocodile's bite if the predator seizes it on a large area that's hard to grip, but getting its legs or snout caught in the crocodile's steel-trap jaws will be big trouble for it.  Any conflict that enters the water will heavily favor the crocodile due to improved mobility and stamina, and a conflict on land will be a close contest that could go either way.  Close to 50/50 on land, Nile crocodile wins in water.

Cougar vs Wild Boar: A wild boar can weigh twice as much as a cougar, and some may weigh even more.  A cougar is a very athletic cat that is skilled at stealth and ambush.  Its speed, agility, weaponry (jaws and claws), and killing experience will help it in any conflict.  A cougar can bring down animals much larger than itself (like elk) by using ambush, but a face-to-face battle can be a challenge if the opponent is larger and well-armed.  A wild boar has very tough hide that gives it protection against predators (and rival boars) and sharp tusks to slash with, so it's no pushover for anything coming against it.  The cougar will need to avoid the offense of the reasonably nimble suid and attempt to latch onto it in such a way to impede its movements.  The boar will be heavier and somewhat stronger than the cougar, and the cat will have difficulty holding it in place in a struggle (and this will make applying a throat bite very problematic).  A cougar can succeed in an ambush, but its chances won't be good.  The cougar might be favored at close weights, but not against a wild boar double its weight.  Wild boar wins.  

White Rhino vs Spotted Hyena Clan: A typical white rhinoceros can weigh over 30 times more than a single spotted hyena, and a maximum-sized one can weigh over 50 times as much.  The rhino can also be twice as tall at the shoulder.  The white rhino is a massive animal with a stocky tank-like build.  Its hide is very tough, and its nose area is armed with 2 large horns (the front one longer than the rear one).  A rhino can make powerful movements and turns that enable it to trample or gore adversaries or attackers.  A spotted hyena is a durable, battle-tested carnivore (and successful scavenger) with solid endurance and extremely strong jaws.  Spotted hyenas occasionally engage in conflicts with lion prides, and many hold up quite well after battling these big cats.  It isn't as nimble or graceful as many other similar-sized predators (like a wolf), but has a decent amount of mobility.  A clan can consist of 3-12 members (and in some cases more than 40).  A group of hunting hyenas will bite at the flanks of the quarry in an attempt to wear it down so the members can pull it to the ground.  This will be extremely difficult to do with a white rhino due to its bulk, toughness, and strength.  A very large clan can succeed with a great deal of persistence, but many clan members will be lost in the attempt.  A group of hyenas won't realistically attempt this with easier targets around.  A healthy, prime white rhino weighing 5,000lbs or more will have little to fear from a typical spotted hyena clan.  Only a tremendously large group with great determination will be a serious threat to this huge herbivore.  Overall edge to white rhino.

Nile Crocodile vs Wildebeest: A large Nile crocodile can weigh anywhere from 2 to 3 times as much as a full-grown wildebeest.  These animals cross paths on occasion, most notably the migration of these antelopes that necessitate the crossing of the crocodile-filled Mara River in Africa (Tanzania/Kenya).  A crocodile can overpower a wildebeest in the water by seizing it in its jaws and pulling it under the water to drown.  A wildebeest is a hardy antelope with curved horns.  They are common prey targets for lions, leopards, hyenas, crocodiles, and a few others.  A wildebeest would have a better chance against a Nile crocodile on land than in the water, but its odds would be poor in either location.  The wildebeest would have much better speed and mobility on land, but would not have a very effective way to injure the armored crocodile without getting too close to the reptile's fearsome jaws.  A crocodile's bite and subsequent movements could easily break the bones of a wildebeest even without the aid of water.  Wildebeests have escaped predation attempts from crocodiles on occasion (at the water's edge and in the water), but they are no match for these toothy predators in typical encounters.  Nile crocodile wins.

Hippo vs Gray Wolf Pack: A large bull hippo can weigh anywhere from 30 to over 45 times as much as a single gray wolf and be over 75% taller at the shoulder.  Hippos have large stout bodies and huge jaws that can open almost 4' wide.  These jaws are armed with huge sharp-edged canines (for biting and slashing) and forward-pointing incisors (for thrusting).  A hippo on dry land isn't quite as formidable because it can't move around as comfortably as it can in the water, but it can attain decent speeds for short distances and make quick movements when it needs to.  Anything taking on a hippo must be careful not to be crushed by its weight or savaged by its jaws while attempting to apply any type of offense.  Subadult hippos may be vulnerable to attack from lions or crocodiles, but an adult is typically safe from predation.  Gray wolves are skilled pack hunters with good endurance and strong bites.  Wolves will cooperate to bring down large herbivores (deer, subadult bison, etc.), and will attack from various sides to divide the prey item's focus and eventually wear it down.  Wolves usually attempt to seize the snout and the tail of a herbivore to hold it in place (while others attack from other angles), but they may elect to employ the bite & retreat approach (they usually target face and flanks of most prey items).  This won't be easy against a hippo.  The hippo's skin is very thick (sometimes as thick as 6") and tough to breach with ease.  It jaws will be a peril to any wolf coming near its "snout" area, and its weight could easily crush an unwary member of the pack.  Wolves won't likely take on an opponent as large as a hippo (wolves won't typically risk members of its pack taking on an especially dangerous adversary), but they actually have the means to succeed.  A gray wolf's lateral quickness (side-to-side; front-to-back) is good enough to keep it from being easily trampled or chomped by the huge herbivore, and several members of the pack can attack with quick bites on the hippo's posterior end without fear of reprisal.  If there are enough pack members (the average is close to 10; much more will be needed), the gray wolves can eventually get this done.  Realistically they won't try, but theoretically they can wear down the hippo with a great deal of time and determination if the encounter occurs on land.  Edge to gray wolves on land (this is conditional on there being many, many determined pack members); edge to hippo in water.

American Bison vs Malayan Tapir: An American bison can weigh 2-3 times as much as a full-sized Malayan tapir and measure over 80% taller at the shoulder.  The American bison is the largest land animal in the Americas, and its weight can exceed 2,200lb.  It has a very robust neck and shoulder area.  The bison's horns extend from the sides of the head and curve upward, and are thick and sharp.  This herbivore fights by charging forward like a battering ram, but will also hook with its horns.  Tapirs have stocky bodies and nasty bites.  They don't seem well-armed from a visual inspection, but can be tough prey items for predators (including big cats).  The largest of these is the Malayan tapir, and despite its large size (over 770lbs on occasion), it is no match for a bison.  The bison will bully the tapir into a retreat, and if the tapir tries to stand its ground, it will likely be killed.  American bison wins.

Kodiak Bear vs Ostrich: A Kodiak bear can weigh 5 times as much as an ostrich.  Kodiak bears are very strong, durable, and have great endurance.  They can bite, use their forepaws to control positioning, and swipe with their long claws.  An ostrich is the largest bird in the world, and can stand close to 9ft tall (the top of the ostrich's back will be a little higher than the shoulder height of the Kodiak bear when the ursid is on all fours).  They usually run (very swiftly for long distances) or hide from danger, but can deliver dangerous kicks with their talons if they are forced to defend themselves.  These kicks make them risky targets for predators like lions and hyenas.  An ostrich's kick can injure a Kodiak bear if the right area is targeted or many of them connect, but the bear will be in the driver's seat once it makes physical contact with the bird.  A swipe from the Kodiak will be able to break the ostrich's neck or kill it swiftly with a strike to the head, and the bear will easily be able to force the bird to the ground once the battle becomes a close-quarters one.  The ostrich's best strategy will probably be to kick quickly and use its speed to stay away from the bear, but it's unlikely the bird will know that's what it needs to do (and even that won't save it).  An ostrich might be able to repel a sun bear or a panda bear (and possibly a sloth bear or a spectacled bear on occasion), but not a 1,500lb Kodiak bear.  The bear will quickly overpower the bird whenever it chooses to.  Kodiak bear 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.
