ビッグヘッドカープ
解説 Definition
ビッグヘッドカープなど、頭が大きいことで知られる淡水魚の呼び方です。特に bighead carp は大型のコイ科魚類として、外来種問題などの文脈でよく出ます。
Bighead usually refers to a large freshwater fish, especially the bighead carp, which has a very large head compared with its body. The word is mainly used in fishing, biology, and environmental contexts. In non-scientific use, it can also have other meanings, but the fish meaning is common in species names.
覚え方のコツ Memory Tip
big＋head をそのまま絵で覚えると定着しやすい語です。魚では「頭が大きい見た目の魚」と literal に取ると、bighead carp の姿につながります。英語の魚名では bighead population や bighead carp のように出るので、まずは淡水魚名として押さえるとよいです。
This one is easy to lock in by its form: `big + head`. It often appears as `bighead carp`, so connect it with fish vocabulary right away. That helps you separate it from the informal human meaning of `bighead` in everyday English.

bighead の語源・成り立ち Etymology
big＋head の複合語。big は北部英語で広まった語、head は古英語 heafod 由来で、文字通り「頭の大きいもの」を指すので、bighead carp は見た目そのままの命名だとわかる。関連語は bigheaded、forehead。
Bighead is a compound of big and head. Head comes from Old English heafod, while big became common in northern English and Scandinavian-influenced speech. The name first follows the literal image of a large head, and from that it was used both for things like fish and for a person seen as too proud.
