Amoeboid of the month

 

Allogromia

You are looking at a division of Lesquereusia spiralis. It is a common species in mesotrophic fresh water bodies. It is remarkable that the new test, the left one, is merely built of small sand grains (xenosomes), while the other shell is mainly built of self secreted or modified elements (idiosomes).
