blacktip grouper
A species of fish, Epinephelus fasciatus, known for its red-tipped dorsal fin spines.
The blacktip grouper is a high-grade fish that lives in warm seas.
I found a fresh blacktip grouper at the market.
Usually written in katakana as a fish name; the kanji form 赤羽太 is rare.
Kanji spelling; rarely used in practice.
The name likely comes from 赤 (red) and 羽太 (grouper), referring to the red-tipped fins.
