Sea Urchin - Planktonic Origins

Barely visible to the naked eye, sea urchin larvae grow and transform into bottom-dwelling urchins.

The Plankton Chronicles series is produced by Noé Sardet, Sharif Mirshak (Parafilms) and Christian Sardet (CNRS) as part of Tara Oceans Expedition and Oceanographic Observatory of Villefranche-sur-Mer (CNRS / UPMC). Fundings by CNRS (INSB / INEE) and by the IBISA program are acknowledged.
