Apple snails survive by breeding faster than predators can eat them. They don't have a need for poison as poison take time and energy to produce which reduces their reproduction rate. Apple snails are also edible that's one of the reason why they were introduced in Asia. Unfortunately, just like many other invasive species, people still preferred to eat the native species and left them alone instead.

Both animals are native here where I live (South Brazil). It was a surprise to see the Mystery Snail as a threat to the Snail Kite because here they hunt almost exclusively this species of snail. You can tell where these birds live by the dead shells they let on the shores. By the way, we call them 'gavião caramujeiro' (Hawk that fishes snails) and 'caramujo maçã' (Apple snail). :D

The place where I use to see them more frequently is at the wetlands areas of the restinga vegetation in the city of Laguna, SC. In wetlands of very near cities (such as Jaguaruna), where the Mystery Snails are absent, the kites are nowhere to be found. Even if there are other species of snails there (planorbid snails, etc). That is why I got so surprised to see these snails as a threat in the video. Here, they seem to be necessary for the birds to live.

Cool. I could learn Portuguese pretty easily, I speak Spanish fluently and I understand lots of Portuguese when I read it. It sounds like Spanish and French mixed to me. I'd love to study a bit and visit Brazil, and Portugal too. I lived in Costa Rica for 9 years and I loved it. I'm sure Brazil would be similar.

It's happening with cane toads in Australia too, native animals have been learning how to get around the poison and making it a meal. The ibis, although not endangered, has even figured out how to eat the entire toad, by shaking the toad so it releases its poison and washing it off in water. Other native birds have been observed learning from this.

Really interesting video! Just one note though, in the aquarium trade, typically the species sold and labelled as the Mystery Snail usually is just the species Pomacea Bridgesii. This species is a fair bit smaller than its other apple snail cousins, about 2 inches, and notably does not usually choose to eat live plants, instead feeding mostly on algae and decaying plant and animal matter. This is actually how you can tell that someone received a different apple snail from a pet store rather than a mystery snail if they start eating aquarium plants. However plenty of other apple snails circulate in the trade and this was definitely how they ended up as invasive species. Being mislabeled as Mysteries here and there probably contributes to this a lot, as irresponsible people are tempted to just toss out a mistakenly sold apple snail after it grows larger than expected and starts eating expensive aquarium plants.

Phenotypic plasticity is such an incredible thing to see. It's why you have groups of the exact same species who have vastly different body plans. Domesticated animals like dogs, cats, horses, and pigs are actually a good example of this, because humans specifically selected for different physical traits, but genetically all the "breeds" are part of the same species (canis familiaris, felis catus, equus ferus caballus, and sus domestica). Even we humans have the same thing, albeit on a smaller scale usually!

The birds were fully equipped to change their beak size on a dime. They probably did just that, multiple times, before humans ever existed, changing their beak size rapidly depending on the local snail population

People have even tried eating these snails, and you'd see why if you held one in your hand; they are SO huge and so easy to gather along the shoreline, it would seem they could be worthwhile as meat. --Especially down here on the Gulf Coast where it would fit right in with the French cuisine. But these are not escargot candidates, unfortunately, taste terrible and are full of parasites. I suspect that would not be the case if they were farmed, as it's undoubtedly the high portion of algae in their wild diets that gives them the 'rotten' taste, and parasites could be easily controlled in a captive rearing setup. But then, a farm doesn't incentivize wild harvesting, which is exactly where they need to be removed from.

sadly the parasite aspect is also why they can't even really be wild harvested for the pet trade. plenty of fish and reptiles eat snails, Puffer fish for one quite literally need a steady diet of them to keep their beaks filed down, but a lot of parasites can pass from snails to fish, and parasite medication is both expensive and as likely to kill the snails themselves.

An idea pulled straight from the air (this is KZread comments after all) - if the species was suffering from food shortages, maybe all individuals were smaller than they were capable of being, given better nutrition. But after the snails had been around for a while one kite discovered a technique to get into the snails' shells, even with its standard beak. It grew larger from more food and taught it's peers/offspring. The young who learned this method grew more healthily and developed longer beaks, which made it even easier to eat the snails.

The island Apple snail is not a mystery snail. All mystery snails are apple snails (as it relates to shape, not species) but not all apple snails are mystery snails. The true mystery snail is P. bridgesii where as the island apple snail is p. maculata. It’s not common to get p. maculata any more in the trade as it is illegal for them to be transported across state lines.

That snail lives in South America and the snail kites also live in South America 🤔 Snail kites are adapted to eat those snails, but in Florida they were adapting to local snails, the evolution probably was taking part before the invasive snail (developing a new smaller species of snail kite), with the invasive snail they probably are going back to what they are in South America, don't you think?

I wish there are some animals that can clear the golden snails in my country.

Fun fact: The island apple snails aren't fully grown when they hatch, in fact, then they're much smaller than newly hatched Florida apple snails. The idea that the eventually larger size of the island apple snail contributed significantly to a 80% population decrease in a few years seems, well, not very well though thru. And come on, how much did the average beak size increase, really? Anywhere close to the difference in "fully grown" Florida and Island apple snails? No, didn't think so. They claim the increase was approximately 1 SD (standard deviation), not to twice the normal size. For those who don't know, an increase of 1 SD where all values ar very similar to each other, as in this case, the change is very small, insignificant in cases like this, and possibly not even real, beaks are not that easy to measure that exact, especially with that shape. Increase in beak size actually happened or not, it can't explain extreme changes in population, if real, that increase represents in the ballpark of a few days of growth for the snail "in season".
