Star sand is not in fact the mineral sand but foraminiferan (protozoan) creatures, which have an external shell (called a "test") made of calcium carbonate. When alive, they inhabit offshore on seaweeds and so on, following death, their remained shells are washed up on the beach and found as star sand. The shell size is around 1 mm with 5?7 processes, making it a real star shape. Okinawan star sand comprises mainly two materials, i.e., Baclogypsina sphaerulata (pored shell body with sharp spiny processes) and Calcarina spp. (thick and round trunk with stout processes), the latter may being more dominant in the listed star sand. Such curious and lovely "sand" may be popular among people worldwide. The listed star sand was produced from the alive creatures collected at the offshore and bleached and dried. Therefore, it is not damaged unlike the washed up one found on the beach, but it may contain a little bit of other materials including other foraminiferans (Marginopora), fine (micro) molluscan shells, and coral bits. Here I would propose buyers a large amount of 1 kg Okinawan star sand, which can be utilized for a gift, personal collection, handcraft and so on.
