The Thaumatomonadida are an order of unicellular eukaryotes that belong to the Cercozoa .
features
The representatives feed heterotrophically . The cells move smoothly, but can also swim. The cell surface is covered with a shell made of silicate flakes that overlap like roof tiles. The cell is flattened and has two flagella that beat differently . These start a little below the tip or on the belly side. Some representatives have only one scourge. The cells form extrusomes . Filopodia are formed below the apex or on the pit of the abdomen . There are cysts . There are representatives that form polynuclear and multi-flagellated plasmodia .
Systematics
The Thaumatomonadida are placed together with the Euglyphida in the group of Silicofilosea . However, they may be more closely related to the Heteromitidae .
The following genera are included in the order:
