Coconuts of French Polynesia is a fascinating blog I found though the coconut Google group. Unfortunately, it's in French, so I read in in Google Translate. Since most of us eat coconut products imported and processed far away, we don't really think about what kind of coconut those foods came from. Apparently many traditional cultures use many types of coconuts. There are oil coconuts, water coconuts, medicinal coconuts, and fiber coconuts for example.
