观察到的萼花臂轮虫的趋光性波长依赖性变化仅部分地告诉我们眼睛感觉色素的光谱特征，因为这些变化也与辅助色素的吸收光谱有关。在420 nm和500 nm之间没有趋光性是由于感觉色素在这些波长缺乏灵敏度。在650 nm和700 nm之间没有响应是由于辅助色素的吸光度下降，因此在这些波长处不再起筛选作用。在350 nm ~ 420 nm和500 nm ~ 650 nm之间存在定向响应，这是由于两种类型的颜料在这些波长的共同干预。
The observed wavelength-dependent variations in the phototaxis of the rotifer Brachionus calyciflorus inform us only partially about the spectral characteristics of the sensory pigment of the eye, since these variations are also linked to the absorption spectrum of the accessory pigment(s).The absence of phototaxis between 420 nm and 500 nm is due to the lack of sensitivity of the sensory pigments at these wavelenghts.The absence of respose between 650 nm and 700 nm is due to a drop in the absorbance of the accesssory pigments, which consequently no longer play a screening role at these wavelengths.The existence of oriented responses between 350 nm and 420 nm and between 500 nm and 650 nmm, is due to the joint intervention of the two types of pigments at these wavelengths.
