zebrafish
C1/C2Technical/scientific, with some presence in general biology education contexts.
Definition
Meaning
A small tropical freshwater fish native to South Asia, with distinctive horizontal blue or black stripes on its body and tail, resembling a zebra's pattern.
Refers specifically to Danio rerio, a species widely used as a model organism in biological and genetic research due to its rapid development, transparent embryos, and genetic similarity to humans.
Linguistics
Semantic Notes
Primarily a scientific term. In everyday contexts, it may simply refer to the ornamental aquarium fish. The research context is strongly dominant in modern usage.

Common Pitfalls
Translation Traps (for Russian speakers)
- Прямой перевод "зебра-рыба" возможен, но в научном контексте используется "данио-рерио" или "данио".
Common Mistakes
- Misspelling as 'zebra fish' (open compound). Confusing it with other striped aquarium fish.
