Description:

Goniomonas (go-knee-owe-moan-ass) pacifica Larsen and Patterson, 1990. Cells are 4 to 10 microns long and with several distinct longitudinal ridges on both sides of the cell. There is a row of about seven to nine ejectisomes near the anterior end of the cell, which is truncated with the posterior end rounded. Two flagella of similar length emerge from a small anterior depression and are directed anteriorly. When the cells are swimming, two flagella diverge in different directions. Less common than G. amphinema in marine sites.
