So I decided to test that Asian clam in orange juice thing to see if they really couldn't care about where they lived. They're complaining about the fact that the juice has pulp, so it seems they do have some standards.
They forgot the introduction of the cane toad to Australia to combat crop bugs. Turns out the toads are sleeping when the target bugs are active...big FAIL. Now the GIANT toads are eating australian's native species out of house and home.
not to mention the video's supposed to be about rabbits & where's the real "planet wonderful" for rabbits on earth? Australia! Poor bilbies! Lets send the cane toads to Guam, since they're proven to eat the brown tree snake, bet he talks about cane toads then lol
Also came beetles, the species bufo marinus was brought in to combat are fast and agile and they climb up the sugar cane while cane toads are not tree frogs so they don't climb up sugar cane to chase after those pesky beetles. Meaning that on top of everything else that's bad about cane toads in Australia they are terrible at the very thing they were brought in to do. With the benefit of hindsight it's clear that they could have avoided that whole mess if they'd done some research and testing beforehand.
my favorite invasive animal? the lighthouse keeper's cat who single-pawedly wiped out ALL THE BIRDS on the island on which the lighthouse was situated. ONE CAT
You're thinking of the Stephen's Island Wren. It wasn't one cat but an explosion of feral cats that almost wiped the birds out before they were described by science. Either way, the species was obliterated within a few years, possibly even one, according to some reports.
Many have heard of the Zebra mussel (invasive) causing havoc all over the great lakes. In their homeland the Round Goby is their main predator. Whether introduced purposefully or accidentally, I am not sure, but they are now found in the great lakes as well. The problem is that while eating the mussels most of the time, they prefer Small Mouth Bass eggs (native to the Great Lakes) when available.
"and they'll live anywhere; lakes, rivers, streams... a glass of orange juice" I've always liked your quips, and that right there is my favorite by far.
In Australia this actually happened with rabbits, although introducing myxomatosis helped reduce the numbers for a while. Aussies are now trained from birth to regard rabbits as pernicious vermin. Cane toads were later introduced as a biological control against certain species of beetle; unfortunately they breed prolifically and are toxic, and so have become a much bigger problem than the beetle they were originally brought in to eat...
Love your show. I want to thank you for something you did in this episode: when you told the story of Bunny, the traditional thing to do would have been to present the normal looking bunnies as male. The females would have had giant eyelashes and possibly a pink bow (or something) on their heads. Instead you depicted the females as normal, and gave the males mustaches to make them identifiable as male. I really like that. It's nice for me to see (for the first time, I think) the females of the species not being depicted as a strange, artificial version of some "true" male form, but rather the opposite (the mustaches were really cute, by the way). A small thing, perhaps - but important. Thank you. It's fun to see some variation when it comes to these things.
What are you talking about? The females were drawn so bizarre. Normal bunnies have mustaches, and female bunnies are very conspicuous in their lack of mustache. Just like real life.
lol, 8:48, was that a Flight of the Conchords reference? If not, I'm going to pretend like it is. EDIT: Yes, it definitely was with the "talk about business time" line. Nice Scishow.
Sort of the opposite really, the Brahminy blind snake is the most successful invasive reptile ever known. It's just inoffensive and doesn't change ecosystems, so nobody cares about the fact that it casually slithers into everywhere that's warm.
First I found the lanthanides episode, and now I’m convinced that someone out there has to have a Drunk Hank playlist. If that person is you, HOOK ME UP ‘CAUSE THIS IS GOLD.
One invasive plant species that is so resilient and dangerous that it does actually remind you of Audrey from Little Shop of Horrors is the Giant Hogweed (Heracleum mantegazzianum). It's originally from the Caucasus and has wrecked havok in a lot of regions of the UK and central Europe where it was introduced. Getting rid of a single specimen can be tricky and dangerous and you can't do so without basic protection gear. The plant just feels alien. Ripley would have recommended orbital nuking...
incorrect. red tail boas are not THE invasive species in the everglades, it is Burmese Pythons. And the majority of the population is from hurricane Andrew destroying several breeding facilities in the Everglades and almost none of the animals that were kept in captivity were recovered. add 15 years later and you get lots of Burmese in Florida that people want to blame on ignorant pet owner. There is a massive difference in the two species (one has live birth while the other lays eggs) and, of course, how they were released into the wild. Dont hate the snake.
Another good example is the Krogan from Mass Effect. They were so powerful and reproduced so fast that the Salarians and Turians had to hit them with the genophage.
humans don't classify as invasive species as An invasive species is a plant, fungus, or animal species that is not native to a specific location (an introduced species), and that has a tendency to spread to a degree believed to cause damage to the environment, human economy or human health. As we don't consider our own species to be one that causes damage to our own economy and or health (there are exceptions e.g. wars, murderer's, corrupt politicians) we don't classify as an invasive species
Except we can only have one baby every 8-10 months and it takes at least 14 years to reach sexual maturity and not every birth is successful so not so similar
you know, that's a pretty ballsy thing to say. Considering White people didn't go around catching people in Africa, intending to enslave them. Africans enslaved their own people, and sold them off to white settlers in exchange for weapons and horses and other such supplies, a horse could equate to 14 slaves iirc. Not denouncing the fact that slavery is barbaric and all, but it is by no means a case of being an invasive species, not only because of what I've just mentioned, but again, invasive species aren't considered invasive to themselves. By that logic re-introduction of native species to their natural habitat are invasive e.g. re-introducing more European bison back into Romania, to help reinforce the population there, so introducing the same exact species to a pre-existing population is invasive to you?. Sure people colonized, but it isn't a case of being an invasive species. Edit: tendency is a relative term and the point still stands
Shows that organisms evolve together (parallel) in order to limit each other and prevent over competition like in the case of an invasive species, pretty interesting how evolution actually prevents detrimental overprogress.
Number one. The animals populating in Florida are neither Red Tail boas or any kind of hybrid, as suggested by a poster. They are Burmese Pythons in (99 out of 100 encounters), subspecies of the Idian Rock Python. And, the population was not created by released pets alone (it does happen sometimes) but by the numerous hurricanes that hit the southeast releasing hundreds of thousands of animal from wildlife importers. Hell, spectacled Caiman, Black Caiman and dwarf Caiman are taking over canals near Florida's international airports because of inept customs officials having to check each shipment. There are many reptile owners dedicated to keeping their animals and then there are the idiots who get them for the "cool" factor. The latter are the ones releasing pet snakes. (many of which have never known the wild since most of our better known species,, ie redtails have consistantly bred in captivity for many many years and importation of them has become less prifitable.)I keep and breed Common red tails along with a couple other species and have been doing so for 20 years. Please don't lump all reptile owners into one category. We are as many and varied as canine or feline enthusiasts.
That would depend on a number of factors. Firstly, does the luminosity come from the sheep's skin or its wool? Secondly, is the luminosity the result of constant biological processes, and will it continue to glow once it's been cut off from the sheep? If it is in the wool, and the luminosity is photoluminescent instead of bioluminescent, then yes. You'd have glow in the dark wool socks. But if it were bioluminescent, then the properties that make the wool luminescent would probably burn out by the time you'd finished spinning the wool into yarn.
You shouldn't even be hunting kangaroos as their some of the species of kangaroo have dwindling numbers! Hunt the rabbits and foxes but not the native animals. Cause they are meant to be there.
The story at the beginning made me think of Okunoshima, an island in Japan which has become overrun with feral rabbits introduced by humans. The island has become something of a tourist destination.
Right but don't mongoose eat snakes? Get some of those to Guam! Wait, they'd just join the snakes in eating the few remaining native bird eggs won't they? ... Drats.
@@calamityjean1525 red belly black snakes live on the ground, birds live in trees & the air, so no, they don't - not unless they're sick. They're not pythons that climb trees to eat eggs in nests, they eat chicken & other ground accessible eggs, but that's all. Cane toads, same story BUT birds eat them & die from the poisoning when they do (unless they're smart like some of the Aussie birds, who do things like turning them over & eating only their bellies that have no poison, or grabbing them by a leg, carrying them to running water & whacking their bodies onto rocks, then washing in the running water, whacking again to release more poison, washing again & repeating 10-20 times until all the poison is gone & then eating them. The only birds smart enough to do that are also smart enough to start their own bushfires in order to flush out prey though, intentionally grabbing half burning sticks from existing bushfires or campfires & carrying them kms across firebreaks like lakes to the location they want the fire & then dropping them & repeating multiple times until the fire starts, so not exactly behaviours that are reasonable for the average intelligence birds to master. Any birds dumber than this are killed by not being able to differentiate the poisonous toads from the native frog foods they eat
@@lilaclizard4504 I was going to ask whether some of Guam's birds nest on the ground, but then I remembered they are gone, so it wouldn't matter, at least unless and until there was some attempt to reintroduce the birds. So good luck with the black snakes and ugly toads.
@@calamityjean1525 I researched this after watching this video (which was a while ago now) basicly they made the decision that because the red belly black snakes & cane toads would also prey on other animals & weren't 100% restricted to preying on the pest species, they were therefore unsuitable to introduce, as were many other animals they investigated (studies were only available behind paywalls though, so I couldn't see what animals they were - were ones not confirmed to be eating the pythons in the wild) but I do wonder in situations like this if the criteria they are using is too tough, like you say, if the birds are gone anyway..... A more interesting suggestion was the Australian Kookabura, likewise ruled out because it eats other animals, not just pythons, but I think it would actually be VERY interesting to research in more detail exactly where the kookaburra would potentially fit into a new eco-system created by it's introduction. Would it maybe replace one of the animals wiped out by the pythons & so change the eco-system, but not in a bad way? 30,000 years ago marsupial tigers went extinct in Australia, but there exact extinction date is hard to even pin down because Indigenous humans replaced them as apex predator & until they were replaced by non-indigenous humans 200 years ago, the eco-system functions completely fine. Plenty of other examples of this in the world too. The studies on Guam seem to be focused on Australian style successful biological control introductions, which are limited to ONLY introducing predators that target exclusively the pest & die out if the pest is eradicated - prickly pear moth, rabbit specific viruses, cattle dung beetles etc. That's a good safeguard, but in a situation like this, I wonder if easing up those rules would still get a better result than no action. Introducing a kookaburra would probably create a situation where a native bird species or 2 would forever be unable to survive alongside it, but if hundreds or thousands of other native species could recover, is that still worth doing?
Did you really need a planet analogy? Rabbits in Australia are a real example, they have transformed a third of the country into desert, that's a 1/3 desert on top of the per-existing arid third. Or perhaps the Koala introduction to kangaroo island where they eating themselves into extinction and no one is willing to cull them due to them being "cute and cuddly".
His checklist for determining invasive species: 1.) Originally found in a different ecosystem. 2.) Transported to different environment through technology. 3.) They go hegemonic on the new ecosystem and take over. 4.) They out-compete the native competitors. 5.) They spread new diseases which devastate native populations. 6.) They hybridize with the natives and dilute its gene pool to the point of extinction. 7.) They massively alter the new ecosystem. 8.) They are really happy to be in the new ecosystem, its a pradise for them, but for everyone else, it's hell. He's talking about White people right?
hummerskickass I think it's OK to call White people "Invasive Species" because you White people think it's OK to call others "Invasive species". I'm just using your own standards against you. Is that a thought crime?
***** Agent Smith from the Matrix said it best. "Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet." Movies blow minds, man.
He forgot to mention prickly pair (Opuntia stricta) that ravaged Australia country side which was quite effectively managed by a particular moth called, quite imaginatively, cactoblastis moth. Though not effective everywhere, where they did like our climate, they were very effective. Then there is the absolute failure of the cane toad which was introduced to stop the cane beetle, but failed epicly and just went to town on our ecosystems, everywhere.
totally! the rabbits & rabbit viruses too & also dung beetles. Australia apears to be the world leader on this stuff, with both the best and worst examples & the clearest examples for a video like this
Just when I thought my subscriptions were getting stale and lame...this rolled around while I was randomly venturing in the wilds of the TH-cam jungle. Suddenly I have about 202 new videos to watch. Let's begin!
Lol, thanks. Well, I'll check them out if I can find them with subtitles. I'm not a big movie fan but I really recommend Let the Right One In and Interview with the Vampire. They're both vampire movies but Interview is really interesting, they're nothing like the modern Twilight stuff we have now. And if you're tired of the usual happy endings Interview is one of the few American movies without a real 'happy' ending.
Can we mention (probably again) that bunnies don't actually eat carrots because it would kill them (because they can't digest them, must like dogs with cooked bones)... they actually just eat the greens off the carrots...
@GabriellaGallelo no, people developed a disease called myxomatosis which killed all the rabbits and then spread across the world breaking havoc on all native rabbit populations. Kind of odd he didn't mention it since it's one of the biggest catastrophes regarding invasive species. This happened in Australia btw.
i live in austin tx, and we have invaseive quaker parrots! they actually dint do much harm so weve kinda just left them alone, but its funny to see a bright blue or green parrot flying around in down town lol
HI Hank. Didn't know you were from my neck of the woods; congratulations on escaping this overly humid/crowded/generally insane area of our great country. They still encourage wild hog murdering pretty heavily, especially in the center of the state where agriculture like fruit production has given way to ranching. Cows, mostly. Beef cows.
Why does Hank look like he has a talking dog, smokes pot, and investigates mysteries with his friends?
Probably cuz he didn’t shave

@@calamityjean1525 I researched this after watching this video (which was a while ago now) basicly they made the decision that because the red belly black snakes & cane toads would also prey on other animals & weren't 100% restricted to preying on the pest species, they were therefore unsuitable to introduce, as were many other animals they investigated (studies were only available behind paywalls though, so I couldn't see what animals they were - were ones not confirmed to be eating the pythons in the wild) but I do wonder in situations like this if the criteria they are using is too tough, like you say, if the birds are gone anyway.....
A more interesting suggestion was the Australian Kookabura, likewise ruled out because it eats other animals, not just pythons, but I think it would actually be VERY interesting to research in more detail exactly where the kookaburra would potentially fit into a new eco-system created by it's introduction. Would it maybe replace one of the animals wiped out by the pythons & so change the eco-system, but not in a bad way? 30,000 years ago marsupial tigers went extinct in Australia, but there exact extinction date is hard to even pin down because Indigenous humans replaced them as apex predator & until they were replaced by non-indigenous humans 200 years ago, the eco-system functions completely fine. Plenty of other examples of this in the world too.
The studies on Guam seem to be focused on Australian style successful biological control introductions, which are limited to ONLY introducing predators that target exclusively the pest & die out if the pest is eradicated - prickly pear moth, rabbit specific viruses, cattle dung beetles etc. That's a good safeguard, but in a situation like this, I wonder if easing up those rules would still get a better result than no action. Introducing a kookaburra would probably create a situation where a native bird species or 2 would forever be unable to survive alongside it, but if hundreds or thousands of other native species could recover, is that still worth doing?
The part on brown tree snakes was super helpful for my uni assignment Thanks! :)
*Reading the suggested scishow videos on the right*
ARGGHHH!! I WANT TO WATCH THEM ALL!!!
Did you really need a planet analogy?
Rabbits in Australia are a real example, they have transformed a third of the country into desert, that's a 1/3 desert on top of the per-existing arid third.
Or perhaps the Koala introduction to kangaroo island where they eating themselves into extinction and no one is willing to cull them due to them being "cute and cuddly".
Whoa, super predators? Calm down there Hillary.
His checklist for determining invasive species:
1.) Originally found in a different ecosystem.
2.) Transported to different environment through technology.
3.) They go hegemonic on the new ecosystem and take over.
4.) They out-compete the native competitors.
5.) They spread new diseases which devastate native populations.
6.) They hybridize with the natives and dilute its gene pool to the point of extinction.
7.) They massively alter the new ecosystem.
8.) They are really happy to be in the new ecosystem, its a pradise for them, but for everyone else, it's hell.
He's talking about White people right?
I guess you think this is ok because it's against white people. Yes it is possible to be racist to us.
hummerskickass
I think it's OK to call White people "Invasive Species" because you White people think it's OK to call others "Invasive species".
I'm just using your own standards against you. Is that a thought crime?
Who exactly are all white people calling a invasive species? If your going to be a racist fuck you can at least be more specific.
***** Agent Smith from the Matrix said it best.
"Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet."
Movies blow minds, man.
It's called several of the fittest
thats it ive watched like 10 videos im subscribing right now :) great video
He forgot to mention prickly pair (Opuntia stricta) that ravaged Australia country side which was quite effectively managed by a particular moth called, quite imaginatively, cactoblastis moth. Though not effective everywhere, where they did like our climate, they were very effective. Then there is the absolute failure of the cane toad which was introduced to stop the cane beetle, but failed epicly and just went to town on our ecosystems, everywhere.
totally! the rabbits & rabbit viruses too & also dung beetles. Australia apears to be the world leader on this stuff, with both the best and worst examples & the clearest examples for a video like this
DONT TRY THE CLAM IN OJ .........clammy : (
The only invasive species you needed to talk about was humans
but we aren't
"You really like it here"
"Me and Daisy are gonna kiss"
HANK YOU ADORABLE DORK!!!
He is totally adorkable.
The major reason that the mongoose didn't eat the rats in Hawaii is that the mongoose is diurnal, the rats are nocturnal. Ooops.
hey look at the worst invading species, us!
Fernando Peña we aren't an invasive species we are a migratory species
Love the beard my man. Keep It going!
New Zealand is plagued by a number of invasive species all on its own. You should do an episode on our little corner of the world.
Just when I thought my subscriptions were getting stale and lame...this rolled around while I was randomly venturing in the wilds of the TH-cam jungle.
Suddenly I have about 202 new videos to watch. Let's begin!
This is my favorite scisho episode
Lol, thanks. Well, I'll check them out if I can find them with subtitles. I'm not a big movie fan but I really recommend Let the Right One In and Interview with the Vampire. They're both vampire movies but Interview is really interesting, they're nothing like the modern Twilight stuff we have now. And if you're tired of the usual happy endings Interview is one of the few American movies without a real 'happy' ending.
Hello hank, and other scishow members!
Pheasants are another species that was introduced and succeeded and not only thrive but also gain a place in the ecosystem as well.
Omg I love this video. The European starling is super pretty!
thanks for helping me on my science homework, Hank!
Love Scishow Thanks so much!!!
Can we mention (probably again) that bunnies don't actually eat carrots because it would kill them (because they can't digest them, must like dogs with cooked bones)... they actually just eat the greens off the carrots...
@GabriellaGallelo no, people developed a disease called myxomatosis which killed all the rabbits and then spread across the world breaking havoc on all native rabbit populations. Kind of odd he didn't mention it since it's one of the biggest catastrophes regarding invasive species. This happened in Australia btw.
I love the way he light up with the animals. He's just a big ole scientific softy.
I love how he actually made a cover, and most likely wrote all of the book, just for this video.
i live in austin tx, and we have invaseive quaker parrots! they actually dint do much harm so weve kinda just left them alone, but its funny to see a bright blue or green parrot flying around in down town lol
4:02 Why did I just crack up laughing? xD
I love that you just made a flight of the concords reference.
I thought this was going to be about the rabbit situation in Australia. But this was very interesting, also.
I really just wanted a show about Hank reading about bunnies
Considering Hanks recovery in 23 this is so nostalgic
in London (England) we have parakeets and some instances of wild parrot. basicly in summer time there are huge flocks in parks.
I love your delicious science. I've started watcing and I can't stop
Ok, I really hope that other people caught the Flight of the Conchords quote at 8:49. That just tickled me pink.
These videos are amazing, and I would love to use them in my class; however, random inappropriate comments prevent me from doing so.
HI Hank. Didn't know you were from my neck of the woods; congratulations on escaping this overly humid/crowded/generally insane area of our great country. They still encourage wild hog murdering pretty heavily, especially in the center of the state where agriculture like fruit production has given way to ranching. Cows, mostly. Beef cows.
