Girl, 10, finds rare Mexican axolotl under Welsh bridge

It amazes me she chanced upon it at the right time and even knew exactly what it was.
culi•1h ago
Axolotl's have become a global icon. First as an anti-colonial protest symbol for indigenous peoples. But now it's even a creature in Minecraft

Edit: oh the article says as much

> Axolotls as pets have seen a surge in popularity in recent years after they were introduced to video games such as Minecraft and Roblox.

Also, the child seems quite familiar with the wildlife

> She said Evie was "always finding things" like newts and bugs, but said the axolotl discovery was a surprise.

What's even funnier is the mother's reaction who apparently didn't believe axolotl's were real

> "I've been telling Evie all this time that those creatures she watches on YouTube, they're not real.

I stopped trying to correct my kid about wildlife facts when he turned 5…
codezero•1h ago
Yeah, I didn't want to spoil the article with my comment, it was a good read, but it did immediately make sense why they were so popular now. I've met multiple people in passing who own Axolotl. I used to think I was super special that I met a guy who owned one, and I assumed it was because he was a famous neuroscientist, and had some special permission, but now they're relatively common as pets (to a degree).
MBCook•45m ago
> Experts have warned axolotls should never be bought on impulse as they can "very challenging" to look after.

> This is because they have the same environmental, dietary and behavioural needs in captivity as they do in the wild.

I thought this was just odd. Don’t most animals that aren’t heavily domesticated like that? I mean that’s true of most all pet fish, for example.

macintux•38m ago
From another comment here: "you need to be able to keep the water below 24 Deg C, this means spending some money on chillers even in sub-tropical countries"

I think people anticipate needing heaters for certain types of fish, but I'd never have expected to buy a cooling unit for aquatic life.

quickthrowman•20m ago
Yeah, adding in a chiller makes things way more complicated than just adding a resistive heater. A decent looking chiller for an aquarium is ~$1,000, plus you need temp sensors and control wiring to maintain the setpoint properly, and then you need to pray the electricity doesn’t go out. A 1/3rd HP chiller draws around 1kW including the circ pump
fragmede•16m ago
An aquarium backup battery for a simple pump is like $50 for something that'll last a few hours of outage, but for a chiller with that kind of draw, it's a bit more expensive.
JaggedNZ•23m ago
Unfortunately, the whole Minecraft thing caused a lot of people to buy them with little understanding of proper care, so I suspect there's some "that's cool but please don't rush in unprepared" in the hard to keep message. There are also some misconceptions around water quality requirements, they really don't like chemical pollutants, but I have no issues with local municipal water, other areas could have issues and require RO water, etc. but there are plenty of tropical fish keepers in this same situation.

And then there's the water temp thing, that caught me off-guard and I was using frozen water bottles for a few weeks until my chiller arrived, if the tank had been located in a different part of the house it might have been required.

psychoslave•31m ago
First time I learnt about it was while reading The Book of Barely Imagined Beings. Fantastic book.
mikestew•1h ago
Sooo, if they are/were popular as pets, how come there's less than 1000 left worldwide? Those two facts don't reconcile for me.
bombcar•1h ago
"in the wild" might be doing a lot of heavy lifting, or it may be based on subspecies or similar.

I don't really expect to find endangered species at the local pet store.

elzbardico•1h ago
Why not. We found plenty of endagered species at zoos. They are endangered not only as a function of the number of species, but due to their vanishing environments.
JaggedNZ•1h ago
I have three axolotl's in the next room, there are no subspecies to my knowledge, except maybe for some cross breeding with Salamanders in the US.

They are common in scientific research as they have amazing regenerative abilities; they will often mistakenly bite each other's legs off as juveniles (they are not the smartest creatures) and then grow them back in a few weeks, good as new. They made it into the exotic pet trade and now they are quite common in captivity, but now critically endangered in the wild. There are attempts to breed and repopulate them, with some limited success.

Another interesting thing, in many countries and states it is legal to keep an axolotl and illegal to keep a Salamander.

They are actually fairly easy to keep in my experience, with two caveats. 1) you need to be able to keep the water below 24 Deg C, this means spending some money on chillers even in sub-tropical countries. 2) If you have a pair in the same tank (regardless of sexing) you need to be prepared to cull the eggs! (freeze them) Prices here went from ~$50NZ each down to around $10-15 each due to the Minecraft craze.

Ifkaluva•58m ago
Why are salamanders illegal?
bombcar•49m ago
Because they burst into flame! 90% of wizard dwelling fires are caused by salamanders!

(in reality probably the law banning them as pets to protect them didn't include axolotls because the legislature didn't know they existed)

JaggedNZ•36m ago
Often Axolotls have been "grandfathered" into the legal exotic pet trade, and salamanders have not and they tend to be considered separate species, even though biologically it's a very blurry line. Also, it often happens in areas where there is a local wild salamander population that is being protected from poaching.
mikestew•35m ago
They're either an invasive species, and therefore should not be introduced to the area (and you know that many pets will be introduced once the novelty wears off). Or they're native to the area, and should be left alone because they're endangered or otherwise threatened.

Those are just two reasons, but I'd bet they cover a lot of cases.

dmonitor•34m ago
most places ban exotic pets that are able to survive in the local climate to prevent invasive species from outcompeting the local feral cat population.
bryanlarsen•24m ago
You likely don't have wild axolotls nearby so if a pet escapes it'll just die and not affect the ecosystem. OTOH, an escaped salamander might thrive and displace wild salamanders and disrupt the ecosystem. Or carry a disease, or ...
fineIllregister•37m ago
It's a similar story for Venus fly trap plants. It has a tiny habitat so it's exotic. They're easy to breed so it's cheap to start selling them. But their limited habitat is being destroyed, so they are endangered and also on the clearance rack at the garden store.
culi•1h ago
1000 wild ones. There's much more in captivity than in the wild.

They evolved to be quite dependent on the unique agricultural islands in the Valley of Mexico called Chinampas. These were drained by the colonizers. Which is why Mexico City is now facing a severe water crisis and also why these creatures are endangered

mikestew•1h ago
Thanks, that's the clarification I was not getting from TFA.
ZeWaka•43m ago
Also why the whole region has so many sinkhole and similar drainage problems - it's literally built on a lake.
liveoneggs•1h ago
the pet ones are almostly entirely captive bred so they are pretty distinct by now
nom•1h ago
This is so unlikely to happen. There is a good chance that they are not as rare as we currently think, at least in that particular area.
culi•1h ago
They are unique to like 2 lakes in Mexico. This is someone's pet that they dumped there. It would not have survived more than a week in Britain had it not been found.
codezero•1h ago
I think it likely speaks to how much more common they are as exotic pets than they have been in the past. That she found it before it died is surprising, and the longer I think about this story the longer I wonder if they just bought it as a pet and the river discovery was a gag for online clout.
kreyenborgi•59m ago
One in a million chances happen nine times out of ten.

Especially with 8 billion humans wandering around.

janalsncm•1h ago
Indeed, most axolotls in Wales are Welsh axolotls.

But I do wonder how many do live in Wales. If it’s not just an abandoned pet that would be really interesting.

codezero•1h ago
From the article it doesn't appear they've ever been found alive in the wild anywhere but their natural habitat. This was likely a remarkable chance happening where an owner released one and she found it within close succession or else it likely would have died very quickly.

If there is a wild population, that would be an even more amazing story.

poolnoodle•1h ago
Why not leave it in the wild? Now the poor thing has to stare at the inside of a bucket for the rest of its life.
neuralkoi•1h ago
As mentioned in the article, this was almost certainly someone's pet and dumped in the river when they couldn't take care of it anymore. Axolotls are endemic to Mexico.
loloquwowndueo•1h ago
Not its natural habitat - it would probably die in winter

Axolotls are somewhat popular as pets so I’m thinking someone got rid of theirs by tossing it in the river and the girl just happened to find it afterwards.

Far more plausible explanation than “found in the wild 9000km and an ocean away from its place of origin”

reactordev•1h ago
They freeze and thaw like Iguanas do in Florida. They can’t survive prolonged cold temperatures but when it does get to 15c they stop moving.
illwrks•1h ago
I wonder if that's why she had caught it so easily, not many people are visiting the UK for it's sunny climate.
scns•53m ago
The UK is sometimes warmer in winter than other european countries further south because of the gulf stream.

mr_toad•14m ago
Yeah, but the water temperature at this time of year is still pretty cold.
oidar•1h ago
It's against the law for it to be in the wild. And the temperature range in which it can survive is quite narrow, it would probably die sometime this year if left alone.
bastardoperator•19m ago
I suspect someone dumped their pet. Considering its from Mexico I also suspect it prefers a warmer water/climate?
WJW•13m ago
1. The article already mentions the parents of the girl who caught it are looking into how to best keep an axolotl and a bigger tank has already arrived.

2. Axolotls can't survive in a Welsh climate. This creature will live much longer as a pet than it would in the wild.

We're speaking English, so why even entertain the idea of pronouncing "axolotl" differently, in that case? The Japanese say "en", but that doesn't seem to inspire anyone else not to say "yen".
mc32•19m ago
That’s like telling the Japanese that “cutlet” is not pronounced “katsu.” It ain’t gonna change. Or even having southerners pronounce squirrel with two sellable. Good luck with that!
