             The coconut palm was once the
             mainstay of life on Pacific islands.
             It provided food, drink, fuel, medicine,
             timber, mats, domestic utensils, and
             thatching for roofs. It remains an
             important subsistence crop on many
             Pacific islands today. Its original
             habitat was sandy coasts around the
             Indo-Malayan region, but it now is
             found over a much wider area, assisted
             by its natural dispersal mechanism, and
             deliberate planting by humans. The
             fibrous husk of the coconut fruit is
             a flotation aid that enables the seeds
             to be carried vast distances by ocean
             waves and currents. The coconut palm
             cannot develop viable fruits outside of
             the tropics and subtropics.

             COCONUT FRUIT
             The fruit of the Coconut Palm weighs
             2¼–4½ lb (1–2 kg). It contains one seed,
             which is rich in food reserves and is part
             solid (flesh) and part liquid (coconut milk).
