To change colour the animal distorts the sacculus form or size by muscular contraction, changing its translucency, reflectivity, or opacity. This differs from the mechanism used in fish, amphibians, and reptiles in that the shape of the sacculus is changed, rather than translocating pigment vesicles within the cell.

Morphological change is the result of a change in the density of pigment containing cells and tends to change over longer periods of time.
