Common Pitfalls
Translation Traps (for Russian speakers)
- Not a common word in Russian either. The direct translation is 'протей' (protey) or 'чоловеческая рыбка' (čelovečeskaja rybka - 'human fish'), but these are also highly specialized terms.
Common Mistakes
- Confusing it with 'elm' (the tree).
- Assuming it is a common noun with broader application.

FAQ
Frequently Asked Questions
They are both amphibians and share neotenic traits (retaining larval features), but they belong to different families. The olm is a salamander in the family Proteidae, while the axolotl is in the family Ambystomatidae.
Due to its pale, pinkish skin colour, which was thought to resemble human flesh in some local traditions where it is found.
No. The olm is completely blind as an adaptation to its lightless cave environment. Its eyes are undeveloped and covered by skin.
Olms have an exceptionally long lifespan for an amphibian, with some estimates suggesting they can live over 100 years in captivity.
