Star sand

One of my co workers brought back some star sand for me from a beach in Taiwan. The star shaped grains of sand are actually tiny exoskeletons of foraminifers, a marine protozoa. These creatures lived on the ocean floor, but their skeletons are washed up by the tide. Walking along a beach like that, you would be walking over millions of skeletal remains of creatures from an alien world you’ll never visit…Nature is strange, and interesting…
