Meaning of Flying Fish, Barracudas, Dorados, Porpoises, Seals

Flying Fish follow the boat Joshua in the first part of the journey in the South Atlantic. The flying fish are followed by the predator fish, the dorado and the barracuda. Flying fish are a good fish to eat, and Bernard catches one that falls on deck, but lets it go since it is dark and he fears it could be a poisonous fish. At points around New Zealand and the Pacific, Joshua is followed by seals and porpoises. At one point Bernard thinks that porpoises help guide him out to the Pacific, avoiding dangerous reefs.
