 Today we looked at the little water tank on my balcony in Dresden, Germany. Since few weeks, green algae started living in the water tank so we thought we might find some more… we found this little rotifer in there, amazing to see the speed it sucks algae in and see the movement of its stomach. Amazing as well the way it can contract and extend.
