Cane toads and the gene shredder program remind me of the krogan from the Mass Effect video game series. A very aggressive and fast reproducing species was uplifted to fight a galactic invasion, and after they won the war they started reproducing out of control. Eventually the other species deployed a sterility plague which meant the majority of females are infertile, keeping their reproductive rate more in line with the other species.

I agree! That was amongst the most awesome of transitions into an advertisement I have ever seen or heard.

I grew up in far north Queensland as a boy, the LZ of the cane Toad... this is an informative video, but I can add a little more information. There is a little monitor lizard that has reached the endangered list because it sees the toad as a frog that is a normal part of its diet, also this little monitor is the ONLY animal to predate on the largest and most aggressive of the crocodiles, the "Saltwater crocodile" this little monitor will sneak into a crocs nest and steal eggs when the parent is off feeding... So now without a reduction in the crocs clutch, all the babies are hatching, this has in turn caused a boost in croc numbers...

By 2050, Australia will either be toad-free or overrun by genetically engineered truck-sized mega toads. Either I'm excited to see it.

There is now a genetic technology that is being used on invasive fish species in the USA. Essentially they genetically engineer males in the invasive species that have two Y chromosomes. This means when they mate they produce all male offspring including 50% YY males. Eventually the number of females in the population fall to such low levels that the invasive species dies out. This might be adapted to get rid of other invasive species, including Cane Toads in Australia.

When it actually did rain.. which was fairly irregular their populations would absolutely explode and we would do exactly what was told here.. get our dads golf clubs and a large bin of any description and cull as many as possible.

As an avid gardener and insect enthusiast, what you said about honeybees at 3:35 is kinda wrong. They've been linked to the decline of both native bees and plant species in many areas in the U.S at least. They outcompete native bee species and hoard resources, while also spreading pathogens and parisites to them from flower-to-flower contact. Honeybees also can't pollinate a lot of native plant species, and on top of reducing the number of native bees able to pollinate them, lead to the overall decline of native plant species too. Honeybees certainly aren't the worst invasive species, and can be neutral or even benificial to some ecosystems. However the damage they cause to native pollinators shouldn't be ignored, especially considering how the whole "save the bees" campaign focuses on them and largely ignored the other bees at risk.

🎯 Key Takeaways for quick navigation: 00:03 🦗 Australian sugar cane crops were attacked by cane beetle grubs, leading to a misguided attempt to control them by introducing cane toads from Hawaii. 00:33 🐸 The introduction of cane toads to control cane beetles in Australia turned into a massive ecological disaster, with toad populations exploding and causing harm to native species. 01:28 🐸 Cane toads have become invasive in Australia, growing large, poisonous, and consuming various prey items but failing to control the cane beetle population. 02:25 🌿 Invasive species harm native ecosystems by outcompeting or preying on native species, and the cane toad's toxic nature makes it particularly destructive. 04:17 🌍 Introduced invasive species disrupt ecosystems where native species haven't evolved defenses against them, leading to negative impacts on native plants and animals. 05:12 ☠️ Cane toads' extreme toxicity and the lack of natural predators in Australia result in native species suffering massive declines and extinctions. 07:33 🥚 Cane toads lay vast numbers of poisonous eggs, and their tadpoles are also toxic, posing threats to predators that try to eat them. 08:56 🐸 Cane toads have evolved to spread faster and are rapidly moving across Australia, potentially due to the longer legs of the toads on the leading edge of the invasion. 10:20 🌱 The invasive cane toads are driving rapid adaptation in native predators, including cannibalistic behaviors and developing tolerance to the toxin. 11:44 ⚙️ Various attempts to control cane toad populations involve culling, trapping, and genetic modification methods to reduce their reproductive success. 14:31 📽️ The cane toad issue inspired humorous documentaries, serving as a reminder of the challenges posed by invasive species and the need for intervention. 16:22 📺 CuriosityStream and Nebula offer educational content and documentaries, supporting creators and providing access to informative material. 17:14 🌍 Signing up for the CuriosityStream and Nebula bundle supports educational creators and provides access to exclusive documentaries and original content.

Haven’t Honey bees been linked to the endangerment of native bee species?

Yeah this video is so retarded, honey bees in north america have wrecked havoc on the ecosystem, but people won't call it invasive because of $$$. Same can be said about crops/livestock, monocultures of potatoes for example have certainly destroyed many ecosystems, but humans only care about our own interest, the term invasive means nothing, humans are after all the most invasive organism of all.

yes, the ´´killer bees´´ are a breed of western and east african honey bees that exists because back on the end of the 50s i guess they introduced east african honey bees to brazil to increase honey production but some of these bees escaped from the kind of quarantine they where and started to spread and reproduce, creating that new variation that is much more defensive and aggro responsive than other kind of honey bees

Great post my friend. I appreciate any awareness being brought to light concerning invasive species.

I've seen Owls swoop down, flip a toad on its back to avoid the poison glands and peck out its organs they're learning and adapting.

even then it could be arbitrary as like a cobra a snake that is evolved to defend it self against bipodal hominins. It has no need for any other animal it naturally encounters to be able to spit venom up to 2 meters in the air (about the height of the eyes of a standing adult human). at that moment there venom against humans is more used as a defence not because it wants to eat us but to want us to not eat/kill them. It's also most likely the reason they developed there ''wings'' so we as humans can see them even better so we know we can and they know we will they to avoid them.

I was aware of the toad invasion from some years already... But totally didn't know about the whole evolution of the native animals as well as the toads themselves. Nature's fast...

These kind of insane invasive species that we did to our selves.. freak me out so much, and think about how much it has changed a amazing ecosystem. Like Australia's ecosystem that before was so unique and different than anywhere on the planet. Before this plague of toads.

Honey bees are invasive, for example in the US where they have crowded and killed off native pollinators and caused declines in some native plant species. They also actively compete with the native bee species and are causing some to go extinct.

1. The cane toad's expression says, "I fully intend to cause trouble-lots and lots of trouble. Just for fun." 2. The cane toad is almost as big as my cat. That is disconcerting. 3. Australian government: "I've made a HUGE mistake."

Actually, they're quite horrible. They pretty much hump anything that moves. Seen em humping half a squashed toad plenty of times. Seen them swim into fish ponds and release their poison, then hump the fish as they jump out the water. They basically wait til they're halfway down a dogs throat before releasing their poison. They're nasty, horrible, ugly things. Source: I'm Australian. There are other animals who deserve your sympathy here, certainly not these ones.

Licking cane toads is something people sometimes do in northern Australia. It's extremely dangerous because it's impossible to know what dosage you will receive. It takes only a small amount to give you life long brain damage.

I’d would have called them Chaswassers.

You make amazing videos. This videos contains a lot of knowledge. Expecting more videos from you😍

5:00 "Venom secreting poison glands" I feel like something is not right, the poison glands secrete venom ? So the toad has to bite to inject it ? Or venom gland that secrete poison ? Then why would the venom glands be on it's back and not somewhere more convenient for injection ?

Good video, although the use of the word "evolution" is somewhat not correct, as the genetics of the toad hasn't been changed, it's only already a natural tendency to be bigger in size when the environment is suitable. Like lions during rainy season when the food is abundant, they will be heavier in weight and reproduce more frequently and efficiently than during draught season without any changes in the genetics.

Okay... _Who the freak_ thought it was a good idea to bring POISONOUS toads in to save their crops??? Like _bruh..._ I could understand non-toxic toads, but seriously!? Poisonous ones?

I wonder if there's been any research into a chemical solution? Their poison is apparently unique to the species, and present in every stage of their life cycle. Could a compound be found that reacts with the poison to either produce a lethal toxic reaction or at least neutralize the poison and leave them subject to normal predation? It would need to be harmless to non-cane toads and practical to produce and distribute in large quantities, as well as breaking down into environmentally safe by-products over time, all of which is a big ask - but it might still be worth looking into if that hasn't been done already. Turning their unique advantage against them would be an ideal solution if possible.

This kinda reminds me of The Simpsons when they introduced the lizards and then they send in Chinese needle snakes to eat them, followed by snake-eating gorillas, which will "simply freeze to death" when wintertime rolls around.

The documentary is called "Cane Toads: An Unnatural History" and I highly recommend it. My favorite part is a scientist holding a struggling cane toad and imitating its mating call completely deadpan.

Okay great video, however u might want to know that the cane toad produces poison not actually venom. You would have to actually orally taste the toads liquid white substance in order for you to feel the effects. Hence venom and poison are two very different things.
