Common Pitfalls
Translation Traps (for Russian speakers)

Common Mistakes
- Using 'cusk-eel' to refer to a true eel (Anguilliformes).
- Omitting the hyphen.
- Capitalizing it as a proper name (it is not).

FAQ
Frequently Asked Questions
No, it is not. It is a fish from the family Ophidiidae, which is in a different biological order (Ophidiiformes) than true eels (Anguilliformes).
They are found in marine environments worldwide, from shallow coastal waters to the deep sea.
Some species are caught as bycatch and may be used for fishmeal, but they are not a common food fish for humans.
The name comes from its superficial resemblance to an eel and its taxonomic relation to other fish like the cusk (a type of cod).
