Fig. 7. Flow patterns around swimming hydromedusae. Arrows represent particle paths at the end of the effective phase of bell pulsation. Arrow lengths represent particle velocities. The bars to the right of each species’ name are a scaling reference and represent a particle velocity of 3 cm s^–1. Medusae diameters (cm) were as follows: Aglantha digitale, 0.68; Sarsia sp., 0.8; Proboscidactyla flavicirrata, 0.54; Aequorea victoria, 4.32; Mitrocoma cellularia, 6.8; Phialidium gregarium, 2.2. Medusae are drawn at maximum contraction.
