Fish pigmentation. Comment on "Local reorganization of xanthophores fine-tunes and colors the striped pattern of zebrafish".

Mahalwar et al. (Reports, 12 September 2014, p. 1362) observed the onset of pigment pattern formation in zebrafish. They concluded that their data do not support our Turing mechanism-based model and presented an essentially different mechanism. Here, we clarify their misunderstanding that may have caused their conclusion and explain past experimental data that do not support their proposed mechanism.
