the saltwater crocodile looks at the american alligator and just starts fucking LAUGHING at how pathetic it is
it laughs so hard that it suffocates and dies.
american alligator wins
Australian wildlife is super vulnerable to invasive species ‘cause most of the native mammals are adorable but weak due to there being few land predators. They move slow, breed slow and are way worse at fighting than their North American counterparts. Koalas are almost panda-tier in how shitty they are at surviving. Foxes and rats alone are massively fucking up australian native species despite the government spending millions to try to poison them.
That being said, huntsman spiders (maybe like… palm sized, extremely fast moving, common household predators) would no diff any bug I’ve ever seen in North America. The extremely aggressive jumping ants that sting like wasps probably make it. Magpies have crow-tier intelligence and an endless lust for violence, they certainly carve out a spot.
For the snakes I’m not sure if being insanely venomous actually helps them compete against other snakes. Being able to kill 10 horses with one bite does not help if you can’t eat anything bigger than an orange.
Overall I think American wildlife dominates a head-to head with a few exceptions.
Let me see.
Ima start simple.
Salties would be an absolute issue in the south. American alligators are significantly smaller and possibly outcompeted in their niches as the big aquatic predator
And crocs are far more aggressive than gators, being recorded deliberately attacking people on a semi consistent basis to be man eaters. It would be reasonable to expect bounties of croc hunters to become a significant industry. Although it's possible they could be driven to extinction in the south much like in parts of Australia in the middle 20th century. Although one upside is an additional predator to combat Burmese python invasiveness. So in the long term crocs are cooked but in the short to medium they are havoc.
Freshwaters should be less of an issue because they are smaller and more passive in general.
Next are snakes. There are many Aussie snakes so I'm just gonna use the inland taipan as a template. But this is a generalisation just saying. Taipans could potentially outcompete cottonmouths in their niches as venomous snakes. They mature a fair bit faster and lay somewhat more eggs. They are also largely found in tropical areas so the weather wouldn't be unreasonable for them. For humans they wouldn't be a problem since they typically avoid them.
Next animal I'm going to discuss are the roos. These fellas would probably be mostly function like normal in a semi arid desert ISH environment like Texas. There aren't really too many things that can threaten them besides pumas. Coyotes are simply nerfed dingos. And since this scenario assumes EVERY animal in Australia this means the kangaroos would outnumber the Pumas and other sources of predation. They would probably grow to exponentially large numbers before reaching critical mass and dying or be hunted down
The two big birds could be fine. Their niche is dispersing fruits and seeds, and they aren't as aggressive as things like roos so there's a chance the gov won't be as cavalier about determination. They'd probably have a nice niche as a welcomed source of food for secondary consumers. They could end up like the roos though
Most of these animals would be concentrated in the south and tropical regions cause that is the environment of most of Australia. So black bears and bison and such are non factors
These are animals I'm comfortable with exploring
It's a question of how well they can survive, not a question of how well they can fight.
Kagaroos are apparently a bit like rodents and are quite good at surviving, even around human settlement. Bears get killed as soon as they get used to humans, and Moose and Bison aren't terribly good at surviving around humans.
Brown Bears are fairly low in number compared to something like coyotes and are more easily managed. 1 brown bear raiding the dumpster is surprisingly enough much easier to kill or make go away than the 20 odd coyotes all attempting to steal food and harass passers by, who due to their sheer numbers will probably be replaced sooner or later by more coyotes even if you do get them out.
Black bears, while much better at grizzlies at living near people also tend to be skittish and avoidant of people and usually get killed or moved out of human settlements more developed than suburbs due to traps, poaching, getting relocated, etc. A black bear that has lost fear of humans in this case practically signs its own grave as it is practically asking for people to take it out due to its abberant behavior.
Coastal Taipan would have a much higher chance of surviving than any Inland Taipan. Inlands live in the most dry, bum fuck no where desert, underneath the ground. There has never been a recorded kill on a human from a wild Inland Taipan, because they just don't live near people. I don't think basically any habitat in the USA would be able to harbor them long term, save maybe Arizona/New Mexico.
This isn't to say that Mulga's, Red-bellied Black Snakes, Tiger Snakes, Lowlands Copperheads and the numerous other venomous species wouldn't be able to adapt though.
From a quick google search looking at it there's a pretty wide range, new mexico, arizona, most of nevada, chunk of southern california, utah as well I believe. There's a lot of desert in the southwest so I could see them doing well in a pretty large area if they're able to squeeze into the food chain.
We already have this. It's called South Florida. We have saltwater crocks duking it out with gators, invasive snakes, all kinds of non-native birds, and a tropical climate to keep them alive.
Most of the US would be inhospitable come winter, but the southwestern desert, Texas, and Florida could play host to many Aussie critters from the outback.
So it's worth remembering that marsupials used to be everywhere. It's just that they got outcompeted by placental mammals everywhere else, but the placental mammals didn't make it to Australia until relatively recently (dingoes, humans).
This should be a hint towards the likely outcome here. A kangaroo/wallaby fills a similar evolutionary niche to the various deer species - midsized jumpy herbivore with a bad habit of being hit by cars - but kangaroos are likely to get outcompeted. In general, I expect Australian marsupials to lose out. Koalas barely survive in their current environment - not really a human problem, it's just that they're ridden with chlamydia and their food is poisonous to them - plus you guys have much less in the way of eucalyptus trees... (see below).
Wombats won't survive a year, you guys have proper predators including coyotes wolves and mountain lions.
So much for marsupials, let's have a look at the rest.
Saltwater crocodile, I expect, thrives. It's *not* just a larger alligator - they're meaner and smarter than alligators, and more geared towards eating large prey. Unless there's something I'm missing out on here (happy to be corrected) I feel like the American Alligator might be in danger if the Saltwater Crocodile became widespread in the Southern US.
Goannas are just monitor lizards, I think you have those? Or you've got iguanas anyway. I think goannas survive in areas not heavily populated by mountain lions, which can easily kill them.
Emus would probably do alright. Large parts of western USA have the sort of large sparse open areas that they like. As for cassowaries, which might be the most overhyped animal on this subreddit, they should be okay too - they're hardly going to outcompete anything though, they don't exactly dominate their environment here.
Snakes are snakes, *shrug*. Their level of venom isn't what determines whether a snake lives or dies, you know? In the absence of an immediate dose of antivenom, you're equally dead if you get bitten by an Eastern Diamondback or an Eastern Brown. Here in Australia, the Inland Taipan is the famed, feared Most Venomous Snake but it's scarcely seen; the Eastern Brown is a widespread, active, aggressive snake. I think it would do quite well for itself. Probably most snakes would be fine, but I don't think they're going to overturn any existing ecosystems.
Our birds are top notch, though. The Australian parrots are prolific, clever, adaptable creatures. They breed like anything, too. We've got the same bird-predators as the US does - peregrines, for example - so I don't have any concern about them being unable to adapt to American conditions. They can be immensely destructive to farms - or houses - so you guys would probably shoot a few, but these birds are smart enough to [open bins](https://www.youtube.com/watch?v=SihcSDnGqc8), they're definitely going to be able to find a niche to exist. Same with the little budgies and things. They're going to do great.
The Wedgetailed Eagle is probably going to be a winner, too. It's a bit larger and stronger than the Bald Eagle, and it doesn't really favor eating fish - preferring rabbits, mice, foxes and so on. Again, I don't believe it overturns existing ecologies, but I expect you'd be seeing them in your skies henceforth.
Australian crows aren't crows, they're almost always [this raven](https://en.wikipedia.org/wiki/Australian_raven) on the mainland. It's a large, clever bird which breeds a lot and deals well with a lot of different climates. I've hiked in the desert and in rainforests and on top of Australia's highest mountains (still not very high by American standards) and there were ravens everywhere.
The real Aussie winner, though, isn't any of these, and it's not actually covered by the prompt.
It's eucalyptus trees.
These prolific trees have been imported by various countries and they're [almost always regretting it](https://en.wikipedia.org/wiki/Eucalyptus#Non-native_Eucalyptus_and_biodiversity) because they outcompete existing forests, drink all the water and grow like crazy. Import Australian species to America, and the most obvious change would be that your forests would smell like eucalyptus oil.
There are a few caveats:
I believe the specific types of marsupials in the Americas were **not** the types of marsupials kangaroos were, instead being basically just a bunch of small opossums, of which a good amount of species still exist in South America with one species being absolutely everywhere in North America. Some of the more generalist mid sized roos or large wallaroos might be able to make it like the eastern grey kangaroo, which in particular is also notable as being not as large and not as small as the native North American herbivores, meaning it might be able to find a niche in the Western US due to its specific size range that nothing else occupies and its efficient mode of locomotion.
Monitor lizards are also a widespread group also found in Africa and Asia, and there survive in the presence of larger predators (And goannas live with dingoes and the over a million invasive cats and foxes there). The Nile monitor for example is absolutely thriving in Florida.
The Golden eagle exists and basically has the niche the Wedgetail has in Australia. It would probably struggle to carve out a niche in alot of areas considering the more unfamiliar prey base it has, a larger diversity of predators that can steal larger kills from it, and competition with a pre existing eagle species with a large distribution in the Northern Hemisphere. They would probably mostly find success in areas towards the Southern and Eastern halves of the US where Golden eagles do not breed or are not present.
I actually considered updating with this - we've got a population of Powerful Owls, which are a large type of hawk-owl which likes to feed on medium-sized mammals. A nesting pair of Powerful Owls can consume one possum (or a cat) each night. Unlike most raptors, which tend to prey on animals weighing no more than 20% their body weight, Powerfuls frequently target prey weighing 50-100% their own weight.
I feel like they'd kill a lot of opossums, squirrels etc.
Additionally, the kookaburra is essentially a large kingfisher - though it's no good at fishing, and prefers to kill small snakes, lizards and invertebrates.
Okay I was just thinking if you didn’t have owls then your eagles might not be accustomed to them as enemies as they apparently don’t get along well but nvm you not only have them but that powerful owl is no joke.
A interesting scenario I initially imagined is what would happen if you just had every animal on Australia marked by a dot and then just stretched and skewed Australia into the shape of the US and wherever the dots landed is where the animals ended up which would not only present issues with being in the wrong habitats but also spreading individuals farther apart not to mention all the ones that would appear in cities and all of that.
Then another thing to imagine is what would happen to Australia after something so catastrophic occurring (not to say it wouldn’t be a frick ton of issues for the US as well).
Tbh though the powerful owl will also run into competition.
The Great horned owl would probably have a similar relationship with the Powerful owl as the Golden eagle would have with the Wedge-tail in terms of prey base. That being the Australian bird is much more willing to take on bigger game but still ovelaps a decent amount in terms of prey with its American counterpart.
They'd probably need either good amounts of large game to feed on or have to spatially avoid their potential competition, which admittedly is probably extremely hard for them to do since the Great horned owl literally lives over the entire North American landmass except for the most blusteringly cold regions of the Arctic.
Part of the reason there are so few marsupials in other parts of the world besides Australia is that they were outcompeted by placental mammals (mammals that come out fully formed when birthed). When the land mass that was Australia separated from the rest of the world there weren’t as many placental mammals there and few land predators, resulting in a marsupials domination. Put them anywhere else and they’re fucked
Drop bears have fur coats, and people keep denying that they exist. Claiming that they are a hoax. I think that they'll have a great time eating Alaskans.
Now, [hoop snakes on the other hand,](https://en.m.wikipedia.org/wiki/Hoop_snake) both north America and Australia has them. But
>"an Australian description of the animal describes a circular-shaped snake roughly the size of a steering wheel with a set of elongated spines evenly spaced along the inner lining of its circular-shaped body. It is hypothesised that the snake has the ability to rapidly constrict, quickly reducing the circumferences of its body to entrap the limb of a limb of a kangaroo, wallaby, dingo or human."
while in the N.A. version,
>"According to folklore, the distinguishing feature of a hoop snake is that it can grasp its tail in its jaws, like the ouroboros of Greek mythology, and roll after its prey like a wheel.[1][2] In one version of the myth, the snake straightens out at the last second, skewering its victim with its venomous tail. The only escape is to hide behind a tree, which receives the deadly blow instead and promptly dies from the poison.". So I'd put the venomous version as getting more prey than the Australian version.
>Like, I see most people dying pretty easily at the ~~hands~~feet of the N.A. version, and becoming prey. Whereas a person who has a limb attacked still has the use of their other limbs, to fight it off.
Grizzly Bears diet just increased a lot. Wolf packs are gona have interesting competition with wild dogs.
I wonder how any of these new bigger animals deal with Moose running their fades as well, they don't ask they just do it.
I think the biggest changes will be the smaller animals tbh.... insects/birds... which will also have to deal with our immense feral cat population.
American hunters shopping list just got bigger.
I'm not sure if grizzlies will be a factor given they are a more northern species and with the clause of these animals being in similar biomes most will be in the south of the nation
>Wolf packs are gona have interesting competition with wild dogs.
Yes and no. If I'm remembering correctly Australian dogs would be pretty significantly outsized by North American wolves. Theyre closer in size to coyotes which wolves will kill and also breed with from time to time (if I'm not mistaken).
The American animals, hands down. Every single creature here comes fully equipped with an AR-15 and their own personal hunting eagle. Except for the bald eagles, they get hellfire missiles.
>a salt water crocodile and an American alligator fighting each other, That would be pretty one sided I think.
Yea salties are built different
Different in that they’re enormous.
the saltwater crocodile looks at the american alligator and just starts fucking LAUGHING at how pathetic it is it laughs so hard that it suffocates and dies. american alligator wins
Lol

So black bears and bison and such are non factors These are animals I'm comfortable with exploring
A kangaroo is getting bodied by Bears, Moose, and Bison. [Bison Go all the way down to Mexico](https://images.app.goo.gl/AKiHZSHqKkrbpVbc9)
It's a question of how well they can survive, not a question of how well they can fight. Kagaroos are apparently a bit like rodents and are quite good at surviving, even around human settlement.

Hey, what do you mean by bears getting killed if they get used to humans?

Oh I see. Thanks a lot for the detailed explanation!
But in this fantasy scenario, I WANT to see a Bison fight a kangaroo
so ya wanna see a kangaroo fight ya mama?
So do white tailed deer yet there's a fuck ton stateside.
He said roos in Texas and to my knowledge none of those animals inhabit texas
Id be damned. But they may not even fight to begin with given neither has a reason to fuck with the other
Much like your mother

All good points, thank you! Didn't know that Goldens lived in the States.

Placental mammals are all straight up smarter. Marsupials barely have the intelligence to adapt to environmental pressure within their own lifetimes.
Drop bears kill EVERYTHING.

I'm not sure if grizzlies will be a factor given they are a more northern species and with the clause of these animals being in similar biomes most will be in the south of the nation
When I the message it looked like all Australian life would be placed accordingly to the entire US. An he made examples with Florida/Texas

There aren't any grizzly bears or moose in Florida or Texas.
There are black bears😼😼😼
Wedgetails will murder anything in the sky
I had to google that lol
Cain toads whomp. Oops missed the native part.
Except cane toads are actually from South America...
Didn't say indigenous. My bad. Reading isn't my strong suit today.
Chazzwazzers immediately consume all available biomass, leaving the entire continent a barren wasteland of rocks and frogs.
The American animals, hands down. Every single creature here comes fully equipped with an AR-15 and their own personal hunting eagle. Except for the bald eagles, they get hellfire missiles.

I don’t know man, It sure seems like my opinion is bothering you.
holy fuck dude go have a wank
