slime flounder
A righteye flounder species (Microstomus achne) found in Japanese waters; the name is usually written in katakana.
I found a rare slime flounder at the market.
Usually written in katakana as a fish name; the kanji form 婆婆鰈 is rare and mainly used in specialized contexts.
Rare kanji spelling; the katakana form ババガレイ is standard.
The name likely derives from 婆 (baba, 'old woman') and 鰈 (karei, 'flounder'), possibly referring to its appearance, but the exact origin is uncertain.
