۱٫ Introduction
The controlled chromomorphism of the skin
is a characteristic employed by several organisms for active camouflage
and, as argued by Messenger (2001), for communication. Octopuses for
example use the tight neuro-muscular interaction of brain impulses with
chromomorphic skin cells to generate extremely sophisticated visual
patterns that run along their bodies for the purposes of social
interaction. Cephalopods such as the common cuttlefish, Sepia
officinalis, shown in figure 1 also rely on the effectiveness of their
chromomorphic appearance to disrupt or confuse the visual attention of
natural predators (Allen et al 2009, Hanlon 2007, Cornwell et al 1997).
There are many different types of biological chromatophores (Mathger ¨
and Hanlon 2007). For example, cephalopod chromatophores contain pigment
granules which are spread under local muscular action, while zebrafish
chromatophores rely on pigmented fluid which is translocated, or
‘pumped’, from a sub-dermal reservoir to a display structure near the
skin surface. All mechanisms however have evolved to maximize visual
impact and hence maximize the potential for evasion, escape or for the
attraction of a mate (Mathger ¨ et al 2009)
