noun
Japanese armorhead
A species of marine fish (Pentaceros japonicus) found in Japanese waters. The name is typically written in katakana, as is common for fish names.
ツボダイは深海魚で、あまり市場に出回らない。
The Japanese armorhead is a deep-sea fish and is not commonly found in markets.
The name likely derives from 壺 (tsubo, 'pot') and 鯛 (tai, 'sea bream'), referring to its shape, but the exact origin is uncertain.
