Summary
[edit]DescriptionÉponge d'eau douce de forme complexe Spongilla lacustris F Lamiot 2017 16.jpg |
Français : Photo subaquatique d'une éponge d'eau douce (Spongilla lacustris) dans l'Authie ( Région Hauts-de-France, Europe de l'Ouest).
Remarque : Malgré plusieurs périodes de pluies dans les heures et jours ayant précédé cette photo l'eau est restée claire, les éponges contribuent à filtrer l'eau, mais pas en hiver pour certaines espèces comme spongilla lacustris (dont les colonies éclairées par le soleil peuvent devenir verte si elles entrent en symbiose avec une algue verte Spongilla lacustris). English: Fresh water Sponge in Authie river (in the Region Hauts-de-France, Northern France).
Note: Despite several rainy periods in the hours and days before this photo the water remained clear, the sponges help to filter the water, but not in winter for some species like spongilla lacustris. |
