35. Secret sand

The 35th chapter of the “Inhabitants of the microworld” series is called “Secret sand”.

The grains of sand forming the beach hide a lot of secrets. Among these grains live a great population of minimal living beings (crustaceans, annelids, flat worms, protozoans, etc.) keeping alive a singular ecosystem. They are, mainly, responsible for cleaning the sea water pushed by waves to the shore and filtered through the free spaces remaining among the irregular grains.

This is the 35th chapter of a series that will bring to us a video per day during this confinement forced by COVID-19.

We hope that you enjoy this initiative, which gives access to a documentary series for free to the world, and you share it with everyone you think will possibly be interested.
