Linguistics
Semantic Notes
A zoological term, primarily used in marine biology and ecological contexts. It is a compound noun where 'leather' describes texture, not material. Not to be confused with 'starfish' as a general term.
Dialectal Variation
British vs American Usage

- Avoid a direct calque 'кожаная звезда' as it sounds like a decorative object. Use the biological term 'морская звезда кожаная' or the Latin name 'Dermasterias imbricata'.
Common Mistakes
- Using 'leather star' as a general term for any starfish (it is a specific species). Confusing it with 'brittle star' (a different class of echinoderm).
