It is actually incorrect to refer to a chromophore as having one shape. There are 4 different shapes of chromatophores, each shape depending on the concentration of the coloured pigment present within the chromatophore itself. The shapes are referred to as: Punctate Puncto-stellate Stellate Reticulo-stellate Reticulate Punctate describes a chromatophore which is roughly circular in shape and represents the fully concentrated state of a chromatophore, thus having its coloured pigment concnetrated. on the other hand, reticulate appears more or less as a network, this showing the most dispersed condition of the pigmented material within the chromatophore. stellate shows the middle condition between the two extremes, as do puncto-stellate and reticulo-stellate.
