Pink beaches are named after microscopic organisms called foraminifera, which have reddish pink shells. These single-celled organisms build shells from water minerals and when they die, they mix with the sand. Coral reefs produce a red pigment from foraminifera, which is washed ashore when corals are destroyed. Limestone sediment, released by parrotfish, also mixes with the red foraminifera to create pink sand. Pink beaches are found on various islands, including Harbour Island, Bonaire, and Komodo Island. Factors contributing to the pink color include a high concentration of foraminifera, unique shell composition, and wave action and tidal patterns.
