Btw až rozjedete trojku, případně šestku a budete rybarit na plazi Okinawa, tak....
The sand in Okinawa, Japan contains thousands of tiny "stars". These "grains of sand" are actually exoskeletons of marine protozoa, which lived on the ocean floor 550 million years ago.
A 1mm star!
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 magnifyin glass to realize 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 million years. These are not true starfish in the literal sense of the word, but protozoa, a mineral shell that can take many forms depending on the species, including a star. Their size generally varies from 38 mm to 1 mm.
