Fig. 5. Three-dimensional reconstruction of the wake behind the cyclically swimming
zebrafish larva (age 3 d.p.f.) (overview panel; letters correspond to flow
diagrams A–C). The vortex rings (red) shown in the overview panel take
time to develop, so the ring immediately behind the tail has not yet fully
formed (blue broken line), as is also evident in C. Transverse cross sections
through the larval flow field (A) in front of and (B) behind the larva. (C)
Horizontal cross-section through the larval wake. The stronger vortices are
due to a slight turn (Fig.
3).
