Sand is normally round… That’s what we think!
But on Hoshizuna Beach in Okinawa, Japan the sand is actually made up almost entirely of star-shaped exoskeletons of tiny creatures.
The “stars” you can see are in fact the exoskeletons of foraminifers.
Most live in the sediments of the sea floor, and can wash ashore after they die.
Did you observe all the different shapes? Awesome
Some biologists suggest some of the fossils could be as old as 550 million years old!
