非洲丽鱼H. Burtoni排列成正方形阵列的马赛克，其具有围绕中心锥体的4个双锥体。光谱吸光度的显微分光光度测量显示，短单锥含有蓝色色素P455。较大的双锥细胞含有P562和P523的红绿色素对。棒散布在整个锥体阵列中，并含有视紫红质P500。光谱形状、颜料吸光度和光产物的λ max是A1基颜料的特征。H. burtoni似乎与重要的视觉识别任务匹配良好。
The retinal receptors of the African cichlid fish, H. burtoni, are arranged in a mosaic of square arrays which have 4 double cones around a central cone. Microspectrophotometric measurement of spectral absorbance reveals that the short single cones contain the blue photopigment, P455. The larger double cones contain red-green pigment pairs of P562 and P523. Rods are interspersed throughout the cone array and contain rhodopsin, P500. Spectral shape, pigment absorbance and the .lambda.max of photo-products are characteristic of A1 based pigments. The retinal receptors of H. burtoni appear well matched to important visual recognition tasks.
