During an field trip with Prof. Dr. Klaus Hausmann (FU Berlin) we were able to observe the final stage of a binary fission in Eufolliculina moebiusi. The binary fission was already completed, the image series shows about the last two minutes of the process, in which the swarmer is about to leave the lorica of the mother cell and finally leaves it to look for a building site for its lorica.

14 images. The specimen was grown on a slide suspended in water.

In 2008, I also had the opportunity on Hiddensee to observe a swarmer emerging from the lorica of the mother cell and to document the construction of the lorica.

First:	The swarmer is looking for a free building site for its lorica.
Second:	The swarmer has found a free building site for its lorica.
Third:	The body has become extremely flattened in order to secrete chitin for the ground plate of the new lorica.
Fourth:	The formation of a sickle-shaped cilia collar at the front end of the hawk moth indicates that the construction of the neck for the lorica has begun.
Fifth to seventh:	Hi-res views on the early state of lorica formation. DOF images.
Eighth to tenth:	Further views of advanced stages of lorica formation. Image #10 shows the completed lorica. DOF images.
Eleventh to fifteenth:	Some stages of peristome lobe formation. DOF images.
