On the beaches of Okinawa in Japan, the sand is mostly made up of foraminifera (a one celled organism that feeds on the minerals found in sea salt).
You just have to take a handful of sand and look at it with a magnifying glass to realise that the grains are pretty little stars.

The same goes for Bermuda, where they also take on a pinkish color due to algae.

These little stars are neither animals nor plants and have been present on earth for 500 millions years. Also they are not true starfish in literal sense of word, but Protozoa, a mineral shell that can take many forms depending on the species, including a star. Their size generally varies from 38mm to 1mm
