Figure 4
Enlarged views of the two sets of terminations composing the discontinuous spiral.
(a) Comparison between experimental and numerical boomerang- and cusp-like terminations from the leftmost white box in Fig. [3](b). (b) Comparison of the “fish-like” terminations seen in rightmost white box in Fig. [3](b). Cusps are the terminations of the very long left fins of the fishes. The color tables are the same ones used in Fig. [3].
