The coconut is a fruit of the coconut palm. The coconut starts off as green and subsequently turns brown, after which the fruit gets its thick shell. The nut can be opened by piercing a hole in one of the three black eyes. The flesh tastes sweet. The coconut water can instantly be drunk and the flesh can be eaten raw. A young coconut has a green rather than a brown shell. Green coconuts contain a great deal more coconut water than the brown coconut.
