Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводите дословно как 'парусная рыба' в научном контексте; используйте 'марлин' только с осторожностью, так как это другой род рыб. Стандартный зоологический термин — 'парусник' (Istiophorus).
Common Mistakes
- Confusing it with other billfish like marlin or swordfish. Using it as a common noun for any fish with a large fin. Incorrect plural: 'sailfishes' is acceptable but 'sailfish' is often used for singular and plural.
