To watch a species, you must be a member of Réseau des observateurs sous-marins.
Watching a species consists of adding it to a list that will send you an email message every time a new observation is added. If you no longer wish to receive these messages, you may easily remove the species from your list at any time. You just have to visit the description file of the species or change your parameters on "Watched Species" on your personal page.
