Retinomotor movements of retinal cones and pigment epithelium melanosomes were studied in the neon tetra, Paracheirodon innesi. The cone myoids clearly contracted during the daytime, but the migration of the total population of pigment granules was less easy to see. However, when rod-shaped melanosomes were measured separately from granular-shaped melanosomes it became evident that the rod-shaped melanosomes, but not the granular melanosomes, did migrate in response to circadian changes in light intensity. Retinomotor movements of both the cones and the rod-shaped melanosomes persisted for at least 2 days in continuous darkness. Microspectrophotometric measurements of spectral transmission of small groups of melanosomes showed that absorption was greatest at shorter wavelengths, but that there was also a distinct absorbance maximum at about 480 nm.
在霓虹脂鲤（Paracheirodon innesi）中研究了视网膜视锥细胞和色素上皮黑素体的视网膜运动。视锥肌样在白天明显收缩，但色素颗粒总体的迁移不太容易观察到。然而，当将杆状黑素体与颗粒状黑素体分开测量时，很明显杆状黑素体而非颗粒状黑素体确实会随着昼夜光照强度变化而迁移。视锥细胞和杆状黑素体的视网膜运动在持续黑暗中至少持续2天。对小群黑素体的光谱透射进行的显微分光光度测量表明，在较短波长处吸收最大，但在约480nm处也有明显的吸光度最大值。
