- Avoid literal translation into components like 'карта черепаха'. The correct zoological term is 'географическая черепаха' or the transliteration 'мап тертл' in specialist contexts.
- Do not confuse with 'сухопутная черепаха' (tortoise) as map turtles are aquatic.
Common Mistakes
- Using 'map turtle' as a general term for any turtle with a patterned shell (it's a specific genus).
