Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'морская лиса' expecting it to be a common term; it is a very specific archaic name for a shark. The modern Russian term is 'акула-лисица' or 'морская лисица', but it's also technical.
Common Mistakes
- Using it as a general term for any ocean predator.
- Confusing it with 'fox shark', which is the same thing, or 'tiger shark', which is different.
