Notes:
Summary Alterations in cell shape of the light-sensitive chromatophores of Centrostephanus longispinus are described. Upon illumination a centrifugal pigment movement starts within extremely thin filopodia which radiate from the cell body. With continued pigment migration the cellular processes increase in length and diameter and give the cell an irregular stellate appearance. Pigment movement within the cellular processes is discontinuous in space and time and may occur independently in single filopodia. The motion of single granules shows characteristic features of a saltatory movement.
