noun
Pacific barrelfish
A deep-sea fish (Hyperoglyphe japonica) found in the Pacific Ocean. The name is usually written in katakana.
メダイは深海魚で、市場ではあまり見かけない。
The Pacific barrelfish is a deep-sea fish and is rarely seen in markets.
The name likely derives from the eye-like marking near the gills, combining 目 (eye) and 鯛 (sea bream), though the exact origin is uncertain.
