Definition
Meaning
A marine game fish, Elagatis bipinnulata, characterised by its long, slender body and distinctive blue-green and yellow stripes.
The term can also be used metaphorically to describe a person or thing that moves quickly and colourfully, or as a compound noun for various objects with a rainbow-like pattern, though this is much rarer. Its primary meaning is ichthyological.
Linguistics
Semantic Notes
This is a fixed compound noun. In non-technical contexts, it would likely be interpreted literally as 'a runner (person/thing) that is rainbow-coloured,' but such usage is not common. The zoological meaning is dominant.

Common Pitfalls
Translation Traps (for Russian speakers)
