与謝蕪村
The dolphins in the novel speak three languages: Primal, Trinary and Anglic. Primal and Trinary are represented as haiku-esque poems (two of the human characters quote Yosa Buson), while Anglic is a hypothetical English-derivative (not to be confused with the actual Anglic family of languages containing modern English, its ancestors, and its close relatives like Scots), rendered for the reader as standard English.
