    It¡¯s all in the name: Hoshizuna no Hama, or Star Sand Beach, located on Taketomi Island in Okinawa, Japan, is filled not with sand made up of rocks and minerals, but instead with microscopic star-shaped particles. These tiny particles have no relation to the stars in the night sky, nor to the starfish that often wash up on shore with them.

    Star sand is actually the remnants of tiny organisms, a group of animals belonging to the subphylum Foraminifera. Each little star is the exoskeleton of small, single-celled organisms known as Foraminifera. Their scientific name is Baculogypsina sphaerulata, but marine biologists call them ¡°living sand,¡± although technically the discarded exoskeletons of the microscopic animals that wash up by the millions on shore are just the dead remains.

    One of the rarest forms of sand, star sand, is both a beautiful sight and a scientific marvel. Found on the Taketomi, Hatoma, and Iriomote islands of Japan, star sand is exactly what the name implies — small, millimeter-sized pieces of sand in the shape of stars. At first glance, the beaches look like any other. Only when visitors take a closer look at the beach they stand on does it become clear that this is no ordinary sand. Despite the small size of the sand particles, beach-goers have no problem seeing this incredible five-pointed star shape with the naked eye.

    Unlike most beaches, the sand on Hoshizuna Beach and other surrounding Japanese beaches is made up not of rocks and minerals, but rather of the remnants of previous organisms. 

    As the waves roll in on the beach, the water carries with it the shells and exoskeletons of these tiny organisms, constructing the unique shoreline. This particular, star-shaped species of Foraminifera, known as Baculogypsina sphaerulata, is found only in the coral reefs of East Asia, making this special sand shape one of the rarest in the world.

    Take a stroll along Hoshizuna no Hama (Star Sand Beach), located on Iriomote Island, and your feet will become encrusted with tiny star-shaped "tests," or shells, produced by microscopic, unicellular protists known as Foraminifera. When Foraminifera die, their shells remain in the sea and the tide brings them ashore. In the case of Hatoma, Iriomote and Taketomi islands in Okinawa, this results in beaches sprinkled with star sand.

    When we think of beaches, we tend to imagine only one type of sand, but there are interesting types of sand around the world, in addition to Japan¡¯s star sand. On Hawaii¡¯s Papakolea Beach, its olivine sand is made up of crystallized magma, and the whole beach is green. California¡¯s Pfeiffer Beach has one of the only locations dominated by garnet sand, meaning entire sections of its beach are purple. New Zealand¡¯s Muriwai Black Sand Beach is made of darkly colored volcanic glass.
