    But captive axolotls are not really true axolotls, they are different from the near extinct wild ones (they have a bit of tiger salamander mixed in). And this really only holds true if people breed their wild-caught aquatic animals - otherwise you are just grabbing a living being from its home and putting it in a tiny cage. There is a place for wild caught fish, but it doesn’t seem very kind to remove them from their habitat to languish in an aquarium for a fraction of their normal lifespan, which is undoubtedly what happens a lot…








  • Yeah from my brief reading it seems they can adapt to food salinity by altering their urine concentrations so I don’t think that’s a huge factor, at least it’s not something that comes into play before the other factors begin to harm them. But if you could fix their skin and buoyancy, diet may start to matter. But their prey is also a different salinity than the water it lives in a lot of the time, and sometimes they eat land animals like birds and such ofc.



  • There are types of freshwater river dolphins in the Yangtze (well, one of these species probably is extinct there as of recently but still) and the Amazon, for example. Sea dolphins can survive in freshwater for awhile but their skin isn’t adapted to it, and it will get damaged eventually. That and the difference in buoyancy in sea water vs freshwater leads to the sea dolphins eventually getting exhausted in freshwater.









  • Also a lot of typhoid and stomach flu type pathogens don’t spread butthole to butthole, they spread via the “fecal-oral” route so… that happens in situations like someone took too small a slice and touches your food (or receipt that you ate to prove they liked your gift) without washing their hands properly.
