Primarily a zoological term. In metaphorical use, it draws on the fish's fearsome physical traits (fangs, bioluminescent lure in the dark) rather than its behavior, which is unfamiliar to most.

- Avoid calquing as 'гадюка-рыба'. The standard Russian zoological term is 'хаулиод' or 'рыба-гадюка' (a direct but established loan translation).
Common Mistakes
- Misspelling as 'viper fish' (two words) is common but the standard is one word.
- Confusing it with the 'viperfish' (one word) and the 'viper fish' (two words, which can refer to other species).

FAQ
Frequently Asked Questions
No. It lives at depths of 200-5000 metres and is too small (typically under 30 cm) to pose any threat to humans.
It is a carnivore, feeding on smaller fish and crustaceans, which it catches with its rapid strike and impales on its fangs.
The bioluminescent lure (called an esca) attracts curious prey in the pitch-black deep sea close enough for the viperfish to strike.
It is exceptionally rare due to the difficulty of collecting and maintaining deep-sea species. They do not survive the pressure change well.
