Fishes with Eye Shine: Functional Morphology of Guanine Type Tapetum Lucidum
In several teleost fishes, guanine type ocular tapeta lucida were studied by conventional light and fluorescence microscopy. Retina1 tapeta lucida were found in the eyes of Chlorophthalmus albatrossis, Chlorophthalmus nigromarginatus, Chlorophthalmus acutifrons, Beryx splendens, Beryx decadactylus, Polymixia japonica and Polymixia bemdti. Choroidal tapeta exist in the eyes of Neoscopelus microc...
متن کاملComparative morphology of the tapetum lucidum (among selected species).
OBJECTIVES The phenomenon of 'eye-shine' is seen in a variety of animal species, and is generally thought to be related to the presence of an intraocular reflecting structure, the tapetum lucidum. The tapetum lucidum is a biologic reflector system that is a common feature in the eyes of vertebrates. It normally functions to provide the light-sensitive retinal cells with a second opportunity for...
متن کاملAbsence of eye shine and tapetum in the heterogeneous eye of Anthocharis butterflies (Pieridae).
Insect eyes are composed of spectrally heterogeneous ommatidia, typically with three different types. The ommatidial heterogeneity in butterflies can be identified non-invasively by the colorful eye shine, the reflection from the tapetal mirror located at the proximal end of the ommatidia, which can be observed by epi-illumination microscopy. Since the color of eye shine is determined by the sp...
متن کاملFine structure of the canine tapetum lucidum.
The structure of the canine tapetum lucidum appears to be basically similar to that described in some other carnivores, but specific distinctions are present. The reflecting rodlets of the dog are similar in their dimensions to those of the cat, but they are more closely packed, resulting in a unique value for the wavelength of maximal reflectance. In addition, the rodlets are less precisely or...
متن کاملElectron Microscopy of the Tapetum Lucidum of the Cat
The fine structure of the tapetum of the cat eye has been investigated by electron microscopy. The tapetum is made up of modified choroidal cells, seen as polygonal plates grouped around penetrating blood vessels which terminate in the anastomosing capillary network of the choriocapillaris. The tapetal cells are rectangular in cross-section, set in regular brick-like rows, and attain a depth of...
