「くじら」の語源は九（最大の）+zilla（とてつもない）

Did you know...?
Japanese call whale "kuzilla", which is "ku" (nine, or max) + "-zilla" (tremendous, gigantic, awful).
Needless to say, the suffix "-zilla" derives from the English monster name "Godzilla", and also used in so many software names like Mozilla, Filezilla, Bugzilla etc.

と言ったら信じますかね？
