The tide changes are very dramatic in Zanzibar. When it's low tide the sea retreats and reveals lots more sand as well as seaweed farms! The local population cultivates seaweed and it is one of Zanzibar's main exports. It is used for cosmetics, pharmaceuticals, and food. The tide was down this morning and it was fun to check out women collecting seaweed and some of the boats that were temporarily marooned on the sand.
