Fig. 4. Migration of melanophores during D. nigrofasciatus pigment pattern
metamorphosis. Early larval melanophores (1, 2, 4, 5) and newly
differentiating metamorphic melanophores (3) change positions as stripes form.
Some changes in position are likely to reflect passive movements due to growth
(e.g. increasing dorsal-ventral separation of melanophores 4 and 5), whereas
others can be explained only by active rearrangements (e.g. relative
dorsal-ventral positions of melanophores 1 and 2). Only selected days from the
complete image series are shown. To maintain the same region of interest,
images in this figure and in Figs
6,
9 and
12 are rescaled across days;
exact sizes and stages are available on request.
