Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'водный скорпион' in a general context; while this is the direct translation, it is not a common animal name in Russian. The more common Russian term is 'водяной скорпион' (vodyanoy skorpion) or the scientific family name 'непиды' (nepidy).
Common Mistakes
- Spelling as two words ('water scorpion') is also accepted, but 'waterscorpion' is the standard single-word form in scientific nomenclature.
- Confusing it with the 'water spider' or other aquatic insects.
