Reproduction occurs by plasmatomy of multinucleate amoebae: they form division rosettes or divide unequally. The cytoplasm clearly differentiated into ectoplasm and endoplasm. Vesicular nuclei (1-32 per cell) with a single central nucleolus. Nuclear envelope surrounded with microtubules in all life cycle stages.
Why was Pelomyxa carolinensis named Chaos Chaos?
In 1926, Asa A. Schaeffer argued that Pelomyxa carolinensis was, in fact, identical to the amoeba that had been seen by Rösel in 1755, the “little Proteus” which Linnaeus had named Chaos chaos. Therefore, he urged that, in keeping with the principle of priority governing biological nomenclature, the name of the organism should be Chaos chaos.
