The invasive crocodilians in Florida can’t out compete the American Alligator. They could possibly out compete the native American Crocodile. This is because the American Crocodile, and the invasive crocodilians are restricted to the southern most portions of the Everglades due the cold winters. They can’t survive, long term, any further north let alone breed. However, the American Alligator is adapted to survive all the way up into parts of the Carolinas. It can even survive under frozen ice as long as it’s nostrils are above the ice. The Nile Crocodile can’t do that. Therefore it can’t out compete the American Alligator.
@@eljanrimsa5843 why couldn’t you have just asked, “what happens if temperatures get warmer”, instead of ending it with a condescending statement? It’s because you aren’t actually concerned with getting an answer. You thought you were so clever, and couldn’t pass up the opportunity to treat someone with arrogant condescension. I have to applaud your confidence. No matter how unfounded it is. So I’ll gladly take this opportunity you have provided me with to point out your unfounded sense of superiority, and show you how not clever you really are. Also, I don’t know why you assumed I’m from Florida (you know what they say about assuming stuff). I’m not. And I do believe in climate change. It’s literally a fact of this planet that the climate will change because change is constant on this planet. Denying climate change is idiotic. Any way, to answer your “question”, based on the fossil record from around 50,000 years ago, when the earth was actually warmer than it is now, alligators would simply move farther north. Their fossils have been found all the way up in the Ohio River valley region (where I’m actually from btw), and in parts of Missouri as well. Areas that are currently too cold for them to inhabit outside the very peak of summer. Meaning they are not found here outside the occasional released/escaped pet (spoiler those die come fall and winter). Based on additional fossil evidence of the other flora and fauna of the region at that time it was very much a subtropical region similar to the Florida of today. Basically, your “gotcha” moment had the fatal flaw of assuming these crocodilians that are more cold adapted than almost any other crocodilian wouldn’t simply take advantage of the increase in temperature to migrate to now accessible areas. I don’t know how your brain latched on to “the crocodiles will be able to spread if it gets warmer”, but thought the alligators wouldn’t? Be better.
@@eljanrimsa5843 also, Alligators and Crocodiles specialize in different types of prey. That’s why the American Crocodile and the American Alligator can co-exist in parts of Florida today. Because they niche partitioned. Yet another reason why the American Alligator can’t be out competed by invasive crocodilians, but the American Crocodile possibly could be. Possibly. Not guaranteed. This is because throughout geologic history crocodilians have repeatedly used the strategy of niche partitioning to avoid competing with other crocodilians, and that normally resulted in diversification. Up to and including land crocodiles that ate plants. Their ability to do this over and over is probably why crocodilians have survived all the way up to modern times. Don’t know why a survival strategy that has worked for them for hundreds of millions of years would suddenly be abandoned.
No clue we had Nile crocodiles in Florida, and Camels have practically made themselves part of the Australian environment it seems. Great video again brother.
I'm surprised the native crocs and gators don't outcompete the Nile crocs. I wonder how long until someone introduces salties to Florida's crocodile party.
Although it would be crazy to see that, there are a few problems with those thoughts. 1. Salties struggle with the idea of seasonal changes, as they don't live in habitat that drops below 50 degrees F. Because of this, a lot of keepers have to move young individuals inside or else they will move around outside of the water and freeze. 2. The 3 juvenile nile crocodiles that went missing in FL were the only animals reported and all found by Chris Gillette and fellow wildlife biologists. There have never been other animals reported, so there is no evidence for any other niles to be in the area. 3. It takes hundreds of thousands-millions of years for animals to evolve, so things like tegus, pythons, and crocodiles/caiman rapidly spreading into colder climates is unlikely to happen for many lifetimes.
Camels were imported to the U. S in the 1800s as well but the animals that escaped or were released didn't thrive due to low numbers. Horses, another introduced animal, have done quite well in the western states.
fun fact; wild horses /were/ native to north america, but died out about 11,000 years ago, so they could be aaalmost argued to be a /re/introduced animal, and it certainly shows why they've been so successful
The first colonizers killed all the horses and camels in the Americas as they had no fear of humans and were easy to hunt. About 90% of the megafauna in the New World was wiped out by the first human colonizers. It was a shameful slaughter that is now being white washed as caused by climate change.
The wild horses in the Western US states came from escapees from Spanish settlers. The horses were so successful that they had colonized the west, had Native American cultures completely change to include them , and only then did they see Europeans again.
There's also a large feral Asian water buffalo population in Brazil Despite their large size I think they do have predators in the form of jaguars and anacondas
The moment you said Australia, I thought that you were going to talk about the Asian water buffalo. I guess that's two large invasive species for Oz, three if you want to add horses, and four if you include donkeys.
I knew the Camels and Hippos would be on the list but I had NO Idea Nile Crocodiles were getting in Florida! Just when I thought Florida couldn't get any scarier...
I knew about the various apes, snakes and lizards in Florida that are invasive, but this is the 1st I'm hearing about Nile Crocs, too. Glad I live up north!
@@momadogy What Apes? Don't tell me they have monkeys and chimpanzees down there too? It's turning into skull island at this point. Just add gorillas to make it complete.
We have a Nandu population here in germany. Its crazy how a big bird of the southern hemisphere can thrive in a much colder environment. We also have several parrot colonies in larger cities, which fill gabs in the ecosystem and only compete on a small scale with native birds. Problems come with animals like racoons or black squirrels. Black squirrels accutally kill our orange squirrels while the racoon has no natural predator and is therefor just like a really big rat.
Parakeets and parrots seem to spread to many large cities. A LOT of big US cities have parakeets, but parakeets don't really exist in the wild anywhere in the USA as far as I'm aware.
@@alecshockowitz8385up until fairly recently (early to middle 1900s) the US was home to the native Carolina parakeet. A massive shame that they went extinct but there’s a chance that one of the introduced parrot species may fill in the emptied niche they left behind in certain areas. Obviously not the preferred solution though
@@beefbeef5342 Fun fact: the Sun Conure is the Carolina Parakeet's closest relative & can be used to revive the species, but not-so-fun fact it's listed as endangered by the IUCN (for whatever that's worth).
Water buffalo in Australia and the mouth of the amazon. But in Brazil it seems to have become a useful resource. In South America Water buffaloes were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the water buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplains.
You'd think they would, but I've seen a documentary on the hippo invasion of Colombia and it's astounding how stupid the Colombian government has handled this problem.
That's what they did to the water buffalo in the NT in Oz they shot them, that was achievable as their range, wet tropic plains, is not that large. Camels, not so much, in Australia the amount of arid land is truly vast (70% of the continent), so yes you can shoot them now and then when circumstances conspire to concentrate them, but, otherwise camel paradise.
Australia also have a massive population of feral horses, donkeys, pigs, sheep, goats, cows, buffaloes as well as camels. All of then are counted in hundreds of thousands or maybe millions. This is not even taking into consideration the farmed livestock - only feral animals.
In Australia we also have the Asian water buffalo, feral pigs, Goats, Horses, Cats, Foxes, Dogs, toads, Birds, Insects, Rabbits and Hare. There is also huge numbers of Deer of many species which are a huge problem in many parts of the Eastern sea board. Incidentally feral cats have done quite well in the Arid Heart of Australia ....sadly.
Did you know water buffaloes are invasive in Uruguay, Brazil and Australia? 🇺🇾🇦🇺🇧🇷 Also caimans are invasive in Florida and Puerto Rico 🇵🇷 🐊 Then we have Chamoise in New Zealand 🇳🇿, The last big species would be the Fallow Deer also in New Zealand 🇳🇿
I'm surprised you didn't bring up the gemsbok in New Mexico. Although from what I hear they're more "controlled" but it's still cause for concern that they could become more invasive
The Burmese python could have made this video. Burmese pythons are one of the largest snake species. It is invasive in Florida. Another invasive giant to Florida. Giant African land snails ? I know that they are not massive animals but they are huge in the world of snails.
Reticulated Pythons, and the Green Anaconda are both honourable mentions for the everglades largest invasive species. depends if you consider length, or weight for largest.
In biology the weight is considered for size. Example, we know a python is larger than an elephant but we also know the elephant is bigger than the anaconda.
Hopefully they act as counter balance to the Niles with any luck. The Niles hang out in groups so if one gets attacked or sent of blood spreads in the water they could rip the snake apart.
Dingoes have been recorded occasionally hunting the large invasive ungulates like deer, pigs, and water buffalo but currently not at a high enough rate to make any real impact on their populations
@@CrownofMischief the entire Silk Road was based on Camels 🐫 bringing everything from sugar spices black powder arrows wine perfumes etc.they are extremely useful there walking is a human jogging speed.also there soft and are not boney like a horse man that hurt my groin but when I was in Egypt being a skinney guy I just floated on them with ease,there way taller than horses and even my extremely obese friend was just picked up with ease.there strong as heck,pick them over a horse.
@@ashleyoasis7948 and that is perfectly fine. But it's also irrelevant to the fact that camels aren't native to Australia and are out-competing local wildlife because nothing is hindering their population. In the native ranges of camels, there are predators like lions, tigers, etc that can hunt them. Right now there isn't anything like that in Australia besides crocodilians, which are limited to water holes.
on a positive note water buffalo along with wild hogs are invasive species on the Indonesian islands but instead of having a negative impact they have actually had a positive one as they ended up filling the role of another species of large native animal that went extinct several hundred years ago as it was the only animal that was eating certain plants on the islands and more importantly was the main food source of the komodo dragon which ended up going extinct on several islands as a result of it's main prey disappearing but the water buffalo and hogs being added to the islands ended up causing the komodo dragons numbers to slowly rebound on the bigger islands and also stop/stabilize or atleast slow there decline on the smaller islands that they still inhabit.
Some people argue hippos could potentially play the same roll toxodon once did in South America. They are dangerous and should be controlled, I do wish there'd be studies to see the exact impact they have. Same with the camel, some argue that they filled the niche of the extinct Diprotodon, and even the crocodile hunter himself has acknowledged these animals tend to eat vegetation that most native animals tend to avoid (stuff that the former used to eat).
Bruh Toxodon had predators like Smilodon, the Hippos do not have anything to hold them back that is concern enough as is especially since they're already the most dangerous animal in Africa. Camels are less concerning but they could possibly be competition for native herbivores in the future
@@kennethsatria6607 Yeah, that's the problem. If Smilodon and Australian apex predators were still around, they wouldn't be much of a problem. That's why I am all for the introduction of closely related or ecologically similar animals under controlled settings; studies have shown this actually helps rejuvinate ecosystems and restore natural functions.
The camels in Australia are lucky as they found the perfect habitat to thrive... Because in their native country they are extinct in the wild. Also I don't believe they are so detrimental to the environment as they are adapted to live in such places, also Australia had bigger mega fauna before humans made them go extinct. The camels are replacing their role. Their feet do not damage the ground as they have soft foot pads, they help spread seeds and disperse plants, they reduce large fires as they keep areas from being overrun with trees etc.
One of the major catagories of invasive species are animals that have moved into niches left open by species extinction. Hippos and camels fall into that catagory. South America had a number of extinct megafauna (glyptodons, ground sloths, toxodon and hemiauchenia) that were doing things similar to what hippos are doing now. In Australia diprotodon probably had a similar impact to camels. In North America equids have returned to their homeland and feral hogs fill niches once occupied by extinct peccaries. I think its a fair question to ask whether these animals are destructive invasives or useful proxies.
Why not both? It seems unlikely it would be an either or situation. The ecosystem changes in response to losing some diversity, it changes again in response to a proxy species appearing and reestablishing that niche. Both will have a mix of impacts on the local life, some will be winners and some losers.
It's really easy to whine for animal rights when you not see the affectance is in short term but not when the animal causes damage that will be seen in future generations. The sacrifice of these species is a necessary evil caused by our own fault, we need to be responsible and accept the consecuences.
@@skaldlouiscyphre2453 The ecosystem changes yes, but in a long rate, where the animals have time to addapt, not in this situation. That's a excuse for not acknowledging the problem.
I don't think Nile Crocodiles will do well in Florida, mostly to do with competition but also to do with climate. Florida is balmy most of the year but it is still uncomfortably cold for tropical reptiles in winter, which is partly why Alligators are more numerous than American Crocodiles as they are more cold resistant. Baby Nile Crocodiles will have to not only survive the gauntlet of predators both native and invasive, they will have to survive multiple winters which might become colder in the future with climate change (as seen by the arctic blast we had not long ago that made it below freezing even in Florida) before they are big enough to actually hold their weight in the environment.
Uk where I live has a shit ton of invasive species(and no, wild boar, eagle owls and beavers don’t count, they were native then extinct then reintroduced illegally/legally). Including: -Signal crayfish, a American crayfish that grows up to a foot in length(I’ve caught ones with 28.7cm length and 9cm claws) and eats anything, kills off native crayfish and causes banks to collapse. -Coypu, a south american beaver look a like which causes huge bank problems and was eradicated supposedly, but there’s been one or two more seen plus near Cambridge you can still see the burrows of them. -Muntjac, tiny asian deer that spread everywhere, terrible for environment since we already have too many grazers -Racoon. -Coati -Terrapins- a shit ton live wild in london and some places here and there in south of England, not breeding for now but still. -Pheasants-something like 6 species recorded in uk, sure everyones seen the common ones but you also have peacock size ones. -Sika deer. -Fallow deer -Asian hornets.Think a hornet the size of your thumb on average, extremely aggressive towards bees and feared so much we eradicate every nest we find. -Puma(has happened a couple of times). -Parrots- London is crawling with them in some places. -Green lizards, think lizards the size of bearded dragons but bright green, on Bournemouth area. -Asceulipian rat snakes, a 7 foot tree snake native to Europe. -Corn snakes, seen a couple living wild. -Wallabies, there’s a fair few places with wild wallabies here and there.
In my personal opinion I think this is just how nature will take its course and our future generations will simply know the once invasive species as "native" ones and I think that is kinda a cool concept of how the world ever changes
Dude!!.....If people moved these animals to where they don't belong, it wasn't "nature" taking it's course. If it weren't for people these invasions would likely never happen. Have you ever taken an I.Q test? You probably shouldn't because your score would probably make you very depressed. So yeah, go on falsely believing you're smart.
In the Everglades, another of the "largest invasive species" include the boa constrictor, which I found surprising that they didn't warrant even a mention along with this list because I vacation find no information about the two species in conjunction, or opposition, to each other. I hate to think of this as a solution, but perhaps higher power weaponry is required to take out the camels? Automatic weapons can affect a much higher affect on an animal than plain shotguns or rifles. Just use all the shooting of indigenous species by the big game hunters in Africa. If we can send all these bastards to Australia, maybe they can do some damage to such animals that will net a benefit for a change.
Saw an article that they plan to start rehoming the hippos Regarding the castration effort... That in mass is probably a somewhat bad idea. While it'll reproduce them breeding, it may make them more aggressive, tho it also may make it less active/depressed. Removing hormones makes it harder for mammels to regulate their emotions -- there been various studies on this particular in rodents (but also in humans and monkeys regarding depression). In dogs, the studies were... A bit crap at being good studies for years or at least the results contributed to misleading conclusion around welfare and behavior -- didn't have good control groups, failed to account for socioeconomic factors (intact dogs tend to be bigger breeds owned by low income people with less vet access, and be work/guard dogs)... With newer studies, they're accounting for that better and finding similar to other mammels -- increased anxiety, increased cancer, overall net negative for health and behavior for both spay and neuter. Cats are different due to their heat cycles being more often and on-demand and their rates of mammary cancer being so high (which results in lower lifespan then hormonally intact cats). Hormone sparing sterilization exists for dogs and research on this investigated, a paper came out in Jan showing results in favour for it over traditional spay and neuter. Check out parsemus foundation for more info on this. There also the ethical issues of reducing an animals sexuality when they're probably into sex (which recent research is showing is more likely then traditional thought). Not sure about hippos specifically, the idea that sex is just for propagation in animals is very outdated (check out bitch: on the female of the species. Been listening to audiobook and it's fascinating). Tldr: vasectomy may have been a better option for the hippos if they continued surgical sterilization options.
Wow! Tsuki I was shocked at the Hypos in Columbia. I was not surprised at Nile Crocodiles in Florida as you said it is a melting pot for invasive species. I was aware of the camels in Australia as I used to live there. I have ridden a tame one in Alice Springs. Also got stuck on the road as a group of them was having a rest. I was not going to try and scare them.
A pygmy hippopotamus was accidentally shot and killed about one hundred and fifty kilòmetres south of Darwin Northern Territory Australia with the hunter thinking it was a very large wild pig, the hippopotamus had escaped from a private zoo and had not been reported.
Greater rhea In northern Germany, Green anaconda in Florida, Banteng in Australia, Wapiti and red deer in New-Zealand, and althought they were eridacated south Georgia reindeers.
Cats in Australia kill more animals than any other predator, goats are another example of wild invasive animals. The goats are an export commodity, as are the camels, these are exported to Saudi Arabia because they are disease free, but this is a small amount. Before western colonisation, all animals in Australia had soft paws, since then most introduced animals are all hard hoofed. This causes damage to the environment, especially around water holes. Plus rabbits are one of the biggest mistakes in Australian history.
Simple answer for the Hippos. Charge the world's rich to come and hunt them. Use the money to fund conservation. Use the meat to feed the poor. It's not 'nice', it's not 'pleasant', but it is necessary.
It's really easy to whine for animal rights when you not see the affectance in short term but not when the animal causes damage that will be seen in future generations. The sacrifice of these species is a necessary evil caused by our own fault, we need to be responsible and accept the consecuences. In Colombia, the problem of hippos haven't been resolved just because of the political backlash, negative for the current governour or president, so the problem has become like a taboo and it's been passed through mandate to mandate.
The Asian water buffalo is another species that could have been added on this list. There's a fairly large feral population of them in the Top End of Australia.
@@Lepocoloco Because here in Australia, we have gun laws. A member of the public needs a licence to get a gun, and depending on the state laws they might also need a permit to go hunting. Up in the Top End there are actually people who round up buffalo and sell them for meat overseas, so it's likely the buffalo have been classified as livestock or hunting game, which means it'd be illegal to shoot them without a permit.
What I want to know is, something that I can never know , what types of impacts will we have on the animals we have moved around the globe? What type of impact will happen due to us even interacting with animals? If they have the ability to change our brain chemistry what are we doing to their brain chemistry. Someone could probably run some computer simulations, I’m sure. But in IDK 50k, 500k, heck even 2k years in the future how is what we are doing now going to pan out. I think it’ll be the age of raccoons with their tiny hands eating human food. But seriously someone run the simulation, or creat a game where people can run one. I’d buy it.
Probably the most invasive species of the lot is the most cuddly -the rabbit -introduced to Australia from Europe the rabbit has led to major problems in Australia where their burrows lead to degradation of the land -a terrible disease called myximatosis was deliberately introduced to stem the rabbit numbers bur eventually the rabbits became immune to this horrible disease which on occasion has infected chickens and even humans.Australia has other destructive invasive species like the cane toad.the camel, the donkey,the pig,the cat,the dog,the fox,the deer,the buffalo,various rodent species and many insect and fish pests like the carp which has degraded the waterways!
Ikr, next thing you know that person is gonna make elephants, chimpanzees, tigers and randomly Emperor Penguins spawn in some remote location in Florida just to mess with us, and they’re gonna somehow resurrect dinosaurs and make them spawn in Florida too lol 😂.
Australia's customs department has some of the heaviest restrictions on just what you can bring here now because of this sort of thing. chamels, wild boars, cane toads, rats, foxes and dogs and cats are destroying many small marsupials only found here. it was theorised that some species we hadnt even found yet might have already been killed off because of this. everyone thought we over reacted when johnny depp bought his dogs here. but we have no rabies, very few other diseases found around the world in cattle and other animals. we would like to keep it that way! also forgot rabbits and ferrets.
I live in Canada and an invasive species here that is really annoying but not large is the zebra muscle I don't know if they have them in America but I'm assuming they do they stick to the bottom of every single boat and every single dock and pretty much everything in the water including probably turtles and other animals when you go into the beach without shoes or sandals on you could risk cutting your feet on these sharp little mollusks and I knew a girl who cut her foot on one and it laid eggs in her foot it was so nasty
Not gonna lie when you soomed in on the Everglades I thought we would get another story about the pythons there, but it turned out to be nile crocs. Never knew they had nile crocs there.
b peterson Nazi orbanuskisser: "my message to Hungarians: what your prime minister is trying to do is to restore the metaphysical foundation of Hungarian culture".
The wild boar is an invasive species here in Brazil. It causes a lot of damages and is the only species that the environmental agency authorized to be hunted.
Would the introduction of dingoes in Australia in the parts where camels roam be the best solution as they get food from bigger animals and the population of camals are not going to drop , just like the wolves in Chernobyl, they have little population compared to the while area but they keep the larger herbivores to a smaller number. Maybe dingoes could do the same.
Hey!, I got an idea for a video you can do, how about 5 species of animal that scientists want to let loose in north America for pleistocene rewilding. 1. From Asia, you have the prezwalskie's wild horse. 2. From Asia, you have the Wild bactrian camel. 3. From Asia and Africa, you have the elephant. 4. From Africa you have the cheetah. 5. From Africa you have the lion.
There needs to be a consensus to rework the name "invasive species" ! None of these species invaded anywhere ....they were involuntarily brought to specific areas by ignorant, narcissistic human beings. I know these species create havoc, but scapegoating them with that name DOES NOT HELP people in those areas want to comply with resolutions (other than killing them.) & How about making the people like Escobar(who brought the animals & adversely infected the landscape with them) pay, or make their estate or heirs pay restitution !?!
They're causing so much damage to the local environment, they almost killed someone, and theres around 20 of them! Do something about it! *Kills one hippo to start doing something about it* NOOO! Why are you killing the invasive animal that's causing so much damage to the local environment and is dangerous to humans?! Jfc...
Bloody hell more invasive large animals...where shall we start. Feral hogs world over. Burmese pythons, water monitors, potentially anacondas, etc in you guest it, Florida. Perhaps pumas and leopards in the UK? More camels in central Asia/Russia. Come on guys help me out. BTW You can see why Florida gets a bad rap just for there pet owners alone!
7:35 Worst case scenario maybe just import the entire foreign ecosystem at this point. In the past when the continents collided this is basically what happened anyway and this along with new diseases created a whole new environment. We will be able to survive no matter the changes I think but everything else I can't say. Nile Crocodiles are kept in check by Hippos in the rives if Africa. Since Hippo now exist wild in the Americas we just call them honoray natives and import some to Florida. The anacondas and pythons will have great trouble taking down full grown adults and the Niles won't touch them either. Deer and other herbivores my in time associate them with safety and hang around Hippo hang outs in the Everglades sort of like wildebeast, zebra, and impala do. It's not ideal but Niles are incredibly terrorial and hang out in groups. They will be worse than the snakes if allowed to spread. I'm just glad Florida doesn't have Salt Water Crocodiles yet as that might cripple the manatee population.
Those hippos will do well until someone comes up with a good recipe for hippo meat! Don't understand why those camels are just being shot and left to just rot. Camel skins have long been used throughout the Middle East. They make beautiful rugs as well as coats and vests. The idea of wasting of what's obviously become an Australian resource is nothing less than senseless. Most people have no idea, along with the American alligator, we also have native American crocodiles in Florida. Those Nile crocodiles that have moved in do not breed with their American cousins. The last thing we need in Florida is yet another invasive reptile, especially one that eats people and grows bigger than anything else around here!
