Massisteria marina Larsen et Patterson 1990 ( Figs 1u , 2r )

Observation: Cells are 4–7 μm, normally adhere to the substrate and have a dorso-ventrally flattened irregular body. The cells have delicate pseudopodia with extrusomes, which extend radially from the cell. Two short curved flagella arise from the dorsal side of the cell and are relatively inactive. Description based on observations of four cells.

Remarks: Generally, our observations are in good agreement with the observations of Larsen and Patterson (1990) and Lee and Patterson (2000). Previously reported size ranges are 2–9.5 μm and this species has been reported from marine sites in Australia, Brazil, Denmark, Gulf of Finland, equatorial Pacific and Panama ( Ekebom et al. 1996; Larsen and Patterson 1990; Patterson and Fenchel 1990; Tong 1997a; Tong et al. 1998; Vørs 1992 a, b; Vørs et al. 1995; Lee and Patterson 2000; Al-Qassab et al. 2002, Lee et al. 2003, Lee 2006a).
