FreshwaterSpongillidae

Description:

Description: English: Freshwater sponges (Spongillidae; genus Spongilla?, species Spongilla lacustris?) on the ground of a clear forest pond about 45 cm in depth (photographed from above of the water surface – with the help of a polarizing filter). The antler-like shape is typical for sponges in still water, the green color is caused by embedded single-celled algae. All around there is some waterweed (Elodea sp.). Deutsch: Süßwasserschwämme (Spongillidae; Gattung Spongilla?, Art Spongilla lacustris?) am Grund eines recht klaren Waldweihers in ca. 45 cm Wassertiefe (fotografiert von oben durch die Wasseroberfläche – mit Polfilter). Die geweihartige Wuchsform ist typisch für Standorte in Stillgewässern, die grüne Farbe kommt von eingelagerten einzelligen Algen. Rundherum befindet sich etwas Wasserpest (Elodea sp.).
