How many axolotls are left in the world in 2022?
Only an estimated 700 to 1,200 axolotls now remain. The species was already listed as critically endangered on the IUCN Red List of Threatened Species.
What do salamanders turn into?
The eggs hatch and develop into larvae—tadpoles in frogs and “efts” in salamanders. But occasionally amphibian development takes an odd turn. Sometimes larvae mature to a reproductive stage without undergoing the normal process of metamorphosis for a land-based adult life.
Are salamanders friendly?
If you are interested in keeping a pet that you can simply observe, then salamanders make good pets. They are not animals that enjoy interacting with humans, though, and very few salamanders will appreciate being regularly handled.
Is it OK to touch salamanders?

What happens if axolotls go extinct?
If the animals went extinct before they could complete the sequencing, they would lose the groundwork for many studies that use the axolotl’s unique molecular toolbox. That’s key, because axolotls are one of the most important animals we have for studying regeneration.
Are axolotls blind?
Nope, axolotls are not blind. They simply have poor vision. They don’t have eyelids and they’re sensitive to light, too.
