## What is Dive4Diadema?

A mass extinction has been taking place. The citizen science project Dive4Diadema is searching for the last of the diadem sea urchins in the Mediterranean and Red Sea. With your help we want to investigate the disappearance of the sea urchin Diadema setosum and document its presence or absence in the Mediterranean and Red Sea.

Join us and be part of the citizen science project Dive4Diadema!
