A species of eel, Nettastoma parviceps. Used in biological and fishing contexts.
The duck-billed eel is a type of eel that lives in the deep sea.
Katakana spelling is common for this fish name; usually written in kana.
Kanji spelling is rare and may not be widely recognized; the kana forms are preferred.
The name likely derives from 屑 (kuzu, 'waste' or 'scrap') and 穴子 (anago, 'conger eel'), but the exact origin is uncertain.
