Detailed top view of flow patterns over the same rangeomorph elements of Fractofusus misrai (Re 1 and Re 2) in different orientations relative to the current

Streamlines vary in their paths between current-parallel and current-oblique/perpendicular orientations but are routed by the surface morphology in all cases. Flow velocity is colored along the streamlines according to velocity (red fastest, blue slowest): (A–D) current-parallel (0°), (E–H) current-oblique (52°), and (I–L) current-perpendicular (90°). (A), (E), and (I) are all the case of a small F. misrai under 0.05 m/s flow in different orientations; (B), (F), and (J) are all small F. misrai experiencing a 0.1 m/s flow in different orientations. (C), (G), and (K) show the case of large F. misrai in a 0.05 m/s flow in different orientations; (D), (H), and (L) show the effects of a large F. misrai experiencing a 0.1 m/s flow in different orientations. Current flow from left to right. Velocity ranges from 0 to 0.05, or 0.1 m/s as indicated in this caption. Scale bars 0.1 cm for small and 1 cm for large F. misrai.
