Description:

Massisteria (mass-hysteria) marina Larsen and Patterson, 1990. Cells are 3 to 6.5 microns and dorso-ventrally flattened irregular body. The cells produce delicate pseudopodia with extrusomes, which extend radially from the cell and normally adhere to the substrate. Two short curved flagella arise from the dorsal side of the cell and are relatively inactive. Rarely observed.
