河豚 [ふぐ] – blow fish; fugu

  • 河 [カ・かわ] – river
  • 豚 [トン・ぶた] – pig; pork

Fugu is the fish famous for being so potentially deadly, that only specialized chefs are allowed to prepare it.  I must admit that I had never seen this word written in kanji before today.  My experience is that the word is normally written in hiragana, a somewhat common practice for when oddly-pronounced or complex kanji are involved.  Still, “river pig” has a certain ring to it, don’t you think?
