Interspecies Conflict/New Species


Hey BK, I have some questions

1. I made a new species called "Icaroraptor", I named it that because it's gliding skills are associated with the Greek story of Icarus
2. The Icaroraptor stands 6 feet tall, 8 feet long, it weighs about 600 kg but is very agile, it can run up to 90 kph in short burst but normally runs at 70 kph. It can jump up to 10 feet with it's powerful legs, it has the iconic scythe claw that is 9 inches long and it spits venom, the venom when lands on skin damages skin severely and leaves an open wound, but it is only effective against animals with no or little cover, such as humans, but it can still be used to stun, lastly it preys on a large variety of creatures in it's ecosystem, it can glide from tree to tree eating primates, or take down giant animals if necessary, but it's weaknesses are if alone, giant predators, giant crocs and faster animals. It's intelligence is unchallenged, it has the memory comparable to an elephant's, it can remember it's tactics in taking down difficult prey alone or with a pack, their coordination is comparable to that of chimpanzees and earns them their right

3. I have some battles for the Icaroraptor
  Icaroraptor vs 2 Smilodon
3 Icaroraptor vs a Bull African Bush Elephant
2 Icaroraptor vs White Rhino
5 Icaroraptor vs Wooly Mammoth
4 Icaroraptor vs Wooly Rhino
2 Icaroraptor vs Andrewsarchus
  Icaraptor vs four lions
  Icaroraptor vs short-faced bear, if too powerful, make it two
6 Icaroraptor vs Triceraton
  Icaroraptor vs Xenosmilus
  Icaroraptor vs Helloid

And lastly what animals do you think can live with the Icaroraptor, prehistoric or present, like what predators can compete with it, what prey can outrun or outsmart it and what biome or habitat should it be in, please give me 5 species of predators and 10 species of prey.

Thank you,
From Lawrence

Hello Lawrence.

Icaroraptor vs 2 Smilodons: Smilodon populator weighed about 2/3 the weight of Icaroraptor.  Smilodon was a muscular, robust cat that likely wrestled prey items to the ground and dispatched them with its long upper canines.  Icaroraptor is a dual threat with its scythe claw and ability to spit venom, but won't be able to repel 2 attacking Smilodons with ease.  Icaroraptor will have a small window of time to deliver its offense before the Smilodons grab a hold of it (and its agility will help) and bring it down.  This will be a close battle, but the 2 Smilodons have the edge.

3 Icaroraptors vs a Bull African Bush Elephant: An African bush elephant can weigh over 9 times as much as an Icaroraptor.  The speed and agility of the Icaroraptors will give them the ability to avoid the elephant's offense (tusks, trunk, use of its weight) on most occasions while they deliver slashes, but there's no guarantee they won't slip up.  The elephant can easily kill a Icaroraptor that gets close or gets careless, but it will have difficulty staying in a position to effectively do so against its much quicker opponents.  An initial encounter may favor the elephant, but the intelligence of the Icaroraptors will mean that subsequent encounters will favor them once they get accustommed to dealing with elephants.  Slight edge to the African bush elephant.

2 Icaroraptors vs White Rhino: A white rhino will typically weigh about 4 times as an Icaroraptor, but a large one can weigh 6 times as much.  White rhinos have tough hides, tank-like builds, and good weaponry (use of weight, long frontal horn).  The Icaroraptors won't easily slash into the rhino's hide with their claws, and the venom won't have great effect unless aimed at the eyes (like a spitting cobra might do).  The Icaroraptor's attempts to attack will put them in danger of being trampled (the rhino can make fast turns for its size) or gored.  The 2 Icaroraptors have a decent chance to win, but without time to adapt their techniques with this particular animal, they won't be favored.  Slight edge to white rhino.

5 Icaroraptors vs Woolly Mammoth: The woolly mammoth will weigh about 9 times as much as a single Icaroraptor.  A woolly mammoth is about the same size as an African elephant, but has longer tusks that curve upwards.  It won't offer any offense that's profoundly greater than the elephant, and is facing 2 more Icaroraptors than the elephant did.  The woolly mammoth won't be without hope, but it won't be favored against 5 of these dangerous opponents.  5 Icaroraptors win.

4 Icaroraptors vs Woolly Rhino: The woolly rhino is about the same size and weight as a white rhino, and offers about the same in regards to offense.  The white rhino was slighty favored against 2 Icaroraptors, and the woolly rhino is facing twice as many.  4 Icaroraptors win.

2 Icaroraptors vs Andrewsarchus: Andrewsarchus likely weighed about 2/3 more than Icaroraptor (its exact weight isn't known because its exact build isn't known).  Andrewsarchus was a prehistoric mammal that may have been somewhat wolf-like in appearance.  It had long jaws that were strong enough to crush bone, and may have been a scavenger.  The 2 Icaroraptors will be quick enough to flank Andrewsarchus and attack it with slashes, and although the jaws of the mammal will be a real threat, they should be agile enough to avoid them on most occasions.  2 Icaroraptors win.

Icaraptor vs 4 lions: The Icaroraptor will weigh almost 2 1/2 times as much as a male African lion.  Lions work well together to bring down large animals (like Cape buffalo), and 4 of them will be capable of bringing a Icaroraptor down.  However, the lions will risk injury dealing with a dangerous creature with multiple weapons.  If the lions strategize well, they should succeed more times than not, but may lose a pride member in the process.  Edge to 4 lions.

Icaroraptor vs short-faced bear (if too powerful, make it two): This depends on the short-faced bear that is used.  The Northern one (Arctodus) weighs about 2/3 more than a single Icaroraptor, but a Southern one (Arctotherium) weighs over twice as much.  Bears are durable, have great endurance, and can use their forelimbs effectively in a fight (to grab, swipe, etc.).  They also have strong bites.  Both bears will be slower than Icaroraptor (less lateral quickness), but will have more strength.  Arctodus will have trouble with the speed & agility of Icaroraptor, but should be able to control the fight at close quarters.  Arctodus vs Icaroraptor will be a close battle (probably 50/50).  Arctotherium is much larger, and will be favored against a single Icaroraptor.  2 Icaroraptors will make it closer, and that battle will probably be close to 50/50 as well.

6 Icaroraptors vs Triceraton: A single Icaroraptor will weigh 3 times as much as Triceraton (an anthropomorphic Triceratops from outer space that is a villain in Teenage Mutant Ninja Turtles).  General description of Triceraton: "A large adult male triceraton stands about 6' high and weighs circa 200 kg. It has a very low fat content; all of its weight is in its armored hide, its muscles, and its dense bones. Counting the tail, it is around 11' long. Although an exclusive herbivore, it is very aggressive and territorial, and is very intelligent. It is equally quadripedal and bipedal (it is bipedal while feeding/traveling; it is bipedal in combat). In build, it is like a heavily muscled (particularly in the legs) man with a powerful, alligator-like tail. It has the tough, leathery frill of a triceratops, a massive, crushing beak, and the normal horns (one short, somewhat swept-back nose horn and two longer forehead horns). Its entire body is very heavily armored, similar to rhino skin, with a thick, osteoderm-covered hide and parts of it (the outer surfaces of the arms and legs especially) are essentially impenetrable. The only "weak" areas are its joints and, particularly, the back of its neck, behind its frill.  Weaponry: First and foremost, the triceraton runs at full speed at its opponent and rolls up into a ball, hurtling into them with great force. It needs at least 100 feet to do this with optimum impact. In close quarters, it uses its massive, swift, and powerful tail to stun and knock down its foe. It can also, by crouching down and taking a deep breath first, emit, via glands in the back of its throat, a noxious cloud whose effects are similar to tear gas. The effective range of this gas is about 10 feet with maximum breath. However, the most devastating weapon of the triceraton is, by far, its monstrous bite. Its beak (whose edges are made of a constantly-growing rim of self-sharpening bone) has a tremendous gape, close to 20", and at parity the triceraton has about three times the bite force of a spotted hyena. Since triceraton is about three times the size of a spotted hyena, it has nearly nine times the jaw force of a hyena. It can easily bite a human cleanly in half, as well as nearly anything else it can fit its jaws around. When it feels very threatened or trapped, the triceraton is capable of leaping high into the air and landing repeatedly on its enemy's head. Triceraton does not normally swipe/slash with its arms (albeit it has fairly sharp claws normally used for grasping vegetation, and it does try to grab and grapple in close quarters with them similarly to a bear). It does not use its horns much in serious combat either, albeit sparring males use them to joust.  Attributes and weaknesses: The triceraton can run as fast as a lion for moderate distances and has about the same endurance as one, and is just as ferocious when threatened. Its durability is on par with a rhino, if not more, and no creature can withstand a direct bite. Even if it doesn't get its mouth around its victim's torso or throat, it will cleanly snap off any legs in its way. However, it is not particularly agile in close proximity, about the same as a spotted hyena. Most fit humans should be able to avoid its cannonball attack by moving to the side at the last moment. It always seeks to stun its opponent (by hitting them in its cannonball attack, with its tail, or with its cloud of noxious breath) before getting into position and finishing them off with its killing bite. The majority of agile animals, even though they can do little or nothing to harm triceraton, should be able to dodge its attacks long enough to escape (if they want to)."  Despite the variety of attacks that can be employed by Triceraton, it will be in trouble against 6 Icaroraptors.  The Icaroraptors are simply too big, and their collective efforts will enable them to eventually capture and overcome Triceraton.  The noxious gas will be a problem once emitted, but the damage should be done by then.  Triceraton may be able to win on occasion, but won't be favored.  Edge to 6 Icaroraptors.

Icaroraptor vs Xenosmilus: Icaroraptor was about 50% larger than Xenosmilus (using the top-end estimates).  There's not a great deal of information on Xenosmilus, but from what has been determined so far, it was a formidable animal.  Xenosmilus was a very muscular felid that resembled the Smilodon in a few ways (powerful build, prominent canines, etc.), but was different in other ways.  One of the differences was its bite.  While the Smilodon's "sabers" were made to impale a soft tissue area (throat, belly) to induce blood loss (after which the Smilodon may have disengaged to wait for the prey to bleed to death), the Xenosmilus had shorter canines designed to remove flesh with each bite.  Xenosmilus likely had the same ability to wrestle prey items to the ground that Smilodon had (good range of motion in the shoulder joints), but its bite didn't need to be as precise.  Icaroraptor will need to be careful at close quarters, but should be quick enough to deliver slashes at the imcoming cat.  Its venom may be effective as well (if aimed at the eyes).  Close to 50/50.

Icaroraptor vs Helloid: Icaroraptor will weigh almost 2 1/2 times as much as Helloid.  Here is a description of Helloid (created by Tejas): "A tenacious, 250 kilogram mustelid.  4 inch canines, 4 inch claws.  1500 pound bite force.  Excellent swimmer.  Speed 80 km/h (running).  Mainly terrestrial animal.  Opportunistic ambush predator.  Thick fur with random sharp bristles measuring 1cm in length as defense.  Jet-black in color, superb night-vision, both nocturnal and diurnal.  Excellent sense of smell, able to smell a drop of blood 70m away.  Lives in packs of up to 50 in number, headed by an alpha male and an alpha female.  Females and males equal in size.  Males experienced in combat, but still prefer ambush attack.  Bristles can detect the slightest sound vibrations."  Helloid will be resistant to Icaroraptor's attack initially, but will be too small to easily overpower the larger creature.  The slashes of Icaroraptor's scythe claws will eventually take their toll, but Helloid can win if it can clamp its jaws onto the neck of Icaroraptor.  Helloid wins at parity, but it's giving up too much weight at the given sizes.  Edge to Icaroraptor.

Q: And lastly what animals do you think can live with the Icaroraptor, prehistoric or present, like what predators can compete with it, what prey can outrun or outsmart it and what biome or habitat should it be in, please give me 5 species of predators and 10 species of prey.
A: Because Icaroraptor is presumedly a reptile, it will need to live in an ecosystem (biome) that isn't cold.  Its use of trees will suggest it needs to be in an ecosystem with them.  Warm forests or jungles will be preferable, but it could thrive in certain sections of savannah-like areas as well.  Predators that will probably be able to live with it include lions, hyenas, crocodiles, alligators, pumas, jaguars, caimans, anacondas, harpy eagles, tigers, African wild dogs, tigers, pythons, Komodo dragons, dholes, leopards, cheetahs, fossas, honey badgers, jackals, and a variety of others.  Many predatory prehistoric animals (dinsoaurs and the later mammals) from various times could have lived with it (large theropods, other dromaeosaurids, sabertooth cats, "terror birds", credonts, various canids, etc.).  Among these animals, a few could actually compete with Icaroraptor (in the quest to obtain prey and in direct confrontations with it).  Large predators (and moderately-sized ones that hunt in groups) will have the best chance to do so.  Lion prides, hyena clans, large crocodillians, large theropods like Tyrannosaurus, Allosaurus, Tarbosaurus, Spinosaurus, prehistoric predators like Smilodon, Hyaenodon, Gastornis, Kelenken, Titanoboa, Deinosuchus, Megalania, Postosuchus, Inostrancevia, and others will have the necessary attributes (size, weaponry, strength in numbers, etc.) to compete and possibly predate upon Icaroraptor in certain situations.  In regards to prey items, only a few would be able to outrun Icaroraptor.  Among these will be ostriches, gazelles, impalas, wildebeests, white-tailed deer, red deer, sambar deer, and certain smaller predators that Icaroraptor may pursue as prey (cheetahs, servals, caracals, small canids, etc.).  Nothing will likely outsmart Icaroraptor due to its unchallenged intelligence, but it won't get its way in every situation.  It's ability to glide will help to vary its approach when stalking prey.  It will probably target prey items like wild boar, tapirs, different species of deer, wildebeest, zebra, possibly gorillas, wild horses, Cape buffalo, gaur, giraffes, and others.  The larger prey items will require a group effort, but Icaroraptor likely hunted that way on occasion.  Most ecosystems having to deal with the introduction of Icaroraptor will likely need to radically adapt to this dangerous predator.

* If I didn't answer this last question like you wanted me to, let me know!  Hopefully that is what you were looking for.  Good new species! *  

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.
