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.

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
Thanks, that's the clarification I was not getting from TFA.
Lake Texcoco was only partially drained by the Spanish. The big project to drain the lake was undertaken by President Porfirio Díaz in the early 1900s.
> Which is why Mexico City is now facing a severe water crisis
No it isn't. Mexico city has over extracted ground water for domestic and industrial use and is facing a drought, that's why they have a water crisis. It has nothing to do with the Spanish in the 17th century.
You're spouting a lot of a historical nonsense in this thread.
Also why the whole region has so many sinkhole and similar drainage problems - it's literally built on a lake.
Yup. A lake that used to fuel the single most productive agricultural system humans have ever practiced. It's sad but there is a strong indigenous movement to bring them back. The axolotl actually became a major symbol of indigenous resistance because of this movement

Axolotls have also been used for over 200 years for medical research related to regenerative biology. They’re unique among vertebrates in that they can regenerate nearly every part of their body, even parts of their brain. https://orip.nih.gov/about-orip/research-highlights/amazing-...
Contrary to the report, they are actually not difficult to keep as pets - they are just highly sensitive to pollutants in the water.
The unfortunate case for the wild population, is that they naturally inhabit a location which today has one of the highest human population densities in the world, and hence massive pressure on water resources. We could probably quite easily re-establish a breeding population in remote areas in Europe but would constitute an invasive species and hence wouldn't happen.
As a species, they are not endangered due to their very large populations now in the pet trade (though these then get inbred, become domesticated etc).
"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.
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.
Why are salamanders illegal?

my understanding is that thr light skinned / pink variants are the results of mutation and selective breeding - and obviously racism, light skinned being considered more cute - in the pet population and almost all examples in the wild are dark skinned.

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.
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.
It's a very strange definition. Would you consider domestic chickens "endangered"? Clearly if there are many kept in captivity and bred, there's little chance of them becoming extinct even if there are nearly none in the wild.
There is in fact a difference between domesticated animals and wild animals that are kept as pets.
Do you also find it strange that e.g. various wolves are/have been considered endangered even though dogs exist?

the pet ones are almostly entirely captive bred so they are pretty distinct by now
I believe all captive ones are cross-bred, so are distinct from the native species
