Zebrafish chromatophores, shown here mediating background adaptation, are widely studied by scientists.
A zebrafish pigment mutant (bottom) produced by insertional mutagenesis. A wild-type embryo (top) is shown for comparison. The mutant lacks black pigment in its melanocytes because it is unable to synthesize melanin properly.
FDA research used Zebrafish to show the effects of ketamine on neurological development.
