Tapeta Lucida and the Organisation of Visual Cells in Teleosts
The tapetum lucidum is often typified as a reflecting layer which returns light transmitted through the retina to the visual cells. In primitive fishes tapeta are smooth and mirror-like lying in the choroid. The tapeta of most teleosts are found in cells of the pigment epithelium modified with long processes which extend vitread and contain reflecting material. Considerable variation occurs in the structure of the processes and the organisation of the visual cells. This variation and its implications to vision will be herein discussed.
