Unionoidea Rafinesque 1820

2011-12-03 Austria, Lower Austria, district Bruck/Leitha - Danube bayou which has fallen dry, National Park (140 msm Quadrant 7867/2).German names: Teichmuschel (Anodonta sp.) + Wandermuschel (Dreissena polymorpha)Identified by Andreas Tiefenbach at naturbeobachtung_at: only genus is determinable with the big one*), while he could identify the smaller ones.*) (I think it is rather A. anatina, but A. cygnea cannot be ruled out.)Water levels of Danube river are extremely low, which is why these mussels are lying in the open, on a bayou which has fallen dry.And while it is only normal hat water levels are lowest in early winter (late november and december) they're still at a record low: only ~140 cm at Wildungsmauer, and even below 100 cm at Thebnerstrassl (water levels of Danube river can be checked here - however, only the most recent data, or monthly or yearly stats, so the low of december, 2012 only will be shown there for a limited period of time).For habitat shot please click here.
