Memory Aids
Mnemonic
Think: 'DESert MAN' is wrong—it's a water animal. Remember 'DES' + 'MAN': 'DES' for 'desperate' because it's rare, 'MAN' for mammal.
Conceptual Metaphor
A living fossil / a specialist swimmer in the mole family.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- The Russian word 'выхухоль' (vykhukhol') refers specifically to the Russian desman. Do not confuse with more general terms for mole or shrew.
Common Mistakes

- Mispronouncing as /ˈdɛsmæn/.
