prawn epithelial chromatophores were more disperse and appeared to contain more pigment (Fig.2).
Considerable variation existed between the colour of individual prawns, and it should be noted that these images were selected to visualise the effects quantified using digital images. Prawn epithelial chromatophores were observed to have expanded or contracted in response to exposure to black or white substrates, respectively (Fig. 2). However, the expansion of blue colour was not restricted to the chromatophores themselves, and extended into the tissue between individual
chromatophores (Fig. 2)
