Spectral light sensitivity of isolated chromatophores of the sea urchin centrostephanus longispinus


Comparative Biochemistry & Physiology A 76(2): 279-282
Spectral light sensitivity of isolated chromatophores of the sea urchin centrostephanus longispinus
The chromatophores of the diadematid sea urchin C. longispinus react to changes in illumination: in darkness they have a round or ovoid shape. When subjected to light they change shape to a stellate form by stretching of pigment bearing cellular processes. The pigment cells show a different sensitivity to light between 370 and 650 nm with a maximum of sensitivity between 430 and 450 nm. The extinction curve of pigment shows a maximum between 500 and 540 nm and does not correspond to the spectral sensitivity of pigment dispersion.
