longhorn cowfish
A boxfish with prominent horns above the eyes, found in the Indo-Pacific. The name is a specific biological term; in everyday contexts, it may simply be referred to as a type of ハコフグ.
I saw a longhorn cowfish at the aquarium.
The longhorn cowfish is characterized by its horn-like projections.
ハコフグ is the general term for boxfish, while コンゴウフグ specifically refers to the longhorn cowfish (Lactoria cornuta).
Katakana spelling is standard for this fish name; usually written in kana.
Kanji spelling is rare and mainly seen in specialized contexts; the katakana form is strongly preferred.
The name combines 金剛 “adamantine, extremely hard” with フグ, referring to the fish’s rigid, armor-like body.
