Coconut

A seed, fruit, and nut in one that can float across oceans to colonize new islands/Food & Drinks

The coconut (Cocos nucifera) is the fruit of the coconut palm, and technically a drupe rather than a true nut. It has three layers: a smooth outer exocarp, a fibrous mesocarp (the husk, up to 5 cm thick), and a hard inner endocarp (the shell). Coconuts can float for months and still germinate after crossing thousands of kilometers of open ocean, which is how coconut palms colonized tropical coastlines worldwide. A single coconut contains about 400 ml of coconut water and up to 34 grams of fat in the white meat. Coconut palms produce 50 to 200 fruits per year and can live for up to 100 years.
