taxon notes

In the tapetal area, no melanosomes are formed indicating a nonocclusible tapetum in the Caiman sclerops.

In crocodilians, a semicircular area of the retinal epithelium in the superior fundus shows a fair sulfur yellow coloration and is specialized as a tapetum lucidum.

the tapetum lucidum is an integral part of the pigment epithelium in primitive teleosts (lying in the pro- cesses of the pigmented epithelial cells). It can vary in chemical nature.

Retinal tapeta lucida are common in fish and some reptiles, but rarely occur in mammals. In most of these species the retinal tapetum can be classified as either a lipid (in some teleosts, mammals) or guanine type (in some teleosts, reptiles). Another differentiation can be made among the retinal tapeta lucida based on whether the tapetum is occlusible (found in most of teleosts), or nonocclusible (or static) (found in mammals)

as seen in teleosts, crocodiles, marsupials and fruit bats
