A species of fish. The name is usually written in katakana as コショウダイ.
I saw a crescent sweetlips at the aquarium.
Katakana spelling is common for fish names; usually written in kana.
Kanji spelling is rare and may not be widely recognized; the fish is usually written in kana.
The name likely derives from 胡椒 (こしょう, pepper) and 鯛 (たい, sea bream), referring to the fish's spotted appearance, but the exact origin is uncertain.
