Amoeboid of the month


Pelomyxa palustris

This very large amoeboid is Pelomyxa palustris. It is wide spread and not rare in low oxygen habitats, like sediments in water bodies. It moves by means of so called fountain streaming of its cytoplasm. It contains hundreds of nuclei, each surrounded by endosymbiotic bacteria, which are also present in its highly vacuolated endoplasm. It doesn't have mitochondria.
