portrait
Description:
Portrait of Pompholyxophrys, one of the heliozoon-like amoebae previously assigned to the Rotosphaerida. Pompholyxophrys has a periplast composed of endogenously formed siliceous elements of a single type within a species. These are spherical in the type species P. punicea but may be ovoid (see images of P. ovuligera), discoid or bone-shaped. Radiating spicules are absent. What appear at first glance to be axopodia are, in fact, filopods which lack axonemes and extrusomes. Contracted filopodia may appear granular leading to confusion but close examination of the extended filopodia shows extrusomes are absent. From standing freshwater near Boise, Idaho. Differential interference contrast.
