Fig. 3. Downstream position of flash initiation (X1) by
Lingulodinium polyedrum (filled symbols) and Ceratocorys
horrida (open symbols) as a function of Reynolds number of the flow.
Symbols represent median values with minimum and maximum range for
approximately 40 cells at each flow. C. horrida responded at lower
flow rates, and flashes were typically located further upstream than for
L. polyedrum.
