A frog's chromatophore is a specialized cell that contains pigment granules which allow the frog to change its skin color to match its surroundings and help with camouflage. These cells are controlled by the frog's nervous system and can expand or contract to alter the color and pattern of the frog's skin.

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.
