Did you know?
- The kanji for イルカ, which is 海豚, literally translates to 'sea pig'.
- Because イルカ is written in katakana, it visually matches the script used for foreign loanwords, even though it is a native Japanese word.
- While 'dolphin' is a single category in English, Japanese has a specific word シャチ for the orca, which is biologically a dolphin but treated as a distinct entity.
