snubnosed eel
A deep-sea eel, Simenchelys parasitica, known for its blunt snout and parasitic feeding habits.
コンゴウアナゴは深海に生息する珍しい魚だ。
The snubnosed eel is a rare fish that lives in the deep sea.
The name コンゴウアナゴ combines 金剛 (kongō, 'diamond' or 'vajra', suggesting hardness or strength) with 穴子 (anago, 'conger eel'), but the exact motivation is uncertain.
