chromatophoren.

/ˈkrəʊmətəfɔː/

Forms: Also chromatophor.

Etymology: < chromato- comb. form + Greek -ϕορος bearing, bearer.

1. Physiology. A pigment-cell, possessing contractile processes, contained in the skin of many animals. Esp. applied to those of the Cephalopoda, which by their contraction and change of shape cause a change of colour in the skin.

1873 St. G. Mivart Lessons Elem. Anat. xii. 488 We may find (e.g. in the Chameleon) cutaneous structures termed chromatophores, which are little sacs containing pigment of various colours and each with an aperture, which when open allows the colour to appear.

1881 St. G. Mivart in Nature No. 615. 336 In trout which are kept alive in dark places, the black chromatophores are expanded, and consequently such specimens are very dark-coloured.

2. Botany. [German (F. Schmitz Die Chromatophoren der Algen (1882) 4).] A plastid containing coloured pigments, as a chromoplast or a chloroplast.
