Bonjour,

Je joins la photo d'une étrange plume de mer qui recouvrait les feuilles de Cymodocea dans les Alfac.

Il y avait du mouvement, de l'expansion et de la contraction. Votre mesure serait d'environ 3-4 mm.

Je pense que ce peut être un hydrozoon, mais je ne connais pas l'espèce.

Merci beaucoup
