The tapetum lucidum of gars (Lepisosteidae) and its role as a reflector

Canadian Journal of Zoology, 1974
Eyes of four species of gars were studied, namely, alligator (Lepisosteus spatula Lacépède), spotted (L. oculatus (Winchell)), shortnose (L. platostomus Rafinesque), and longnqse (L. osseus (L.)). The retina is duplex, a yellow tapetum lucidum is present, rods and retinal pigment move, and the tapetum is uncovered in dim light. The visual pigment is a

Studies on the eyes of gars (Lepisosteidae) with special reference to the tapetum lucidum

Canadian Journal of Zoology, 1973
Eyes of gars (Lepisosteus) possess a yellow tapetum lucidum which is located in processes of the pigment epithelium. A yellow reflecting pigment is involved, enclosed in tapetal spheres each about 240 nm in diameter. Retinomotor movements take place: in darkness (or dim light) the black retinal pigment retracts, exposing the tapetum, and the rods ...

Primer designs for identification and eDNA detection of gars (Lepisosteidae)

Transactions of the American Fisheries Society, 2017
AbstractGars (family Lepisosteidae) serve important roles as apex predators in freshwater ecosystems., helping to balance fish populations. Several gar species are exploited as food and game fish, and some species are classified as vulnerable due to habitat loss.

Liver lesions in the gar fish (Lepisosteidae) as biomarkers of exposure

Marine Environmental Research, 1996
Abstract The objective of this research was to identify lesions and diseases in fish as biomarkers of exposure to environmental contaminants from polluted wetlands typical of the Mississippi River Basin. Devil's Swamp, located northwest of Baton Rouge, Louisiana, is an ecosystem contaminated with a variety of metals and organic chemicals.

The larval attachment organ of the tropical gar Atractosteus tropicus Gill, 1863 (Lepisosteiformes: Lepisosteidae)

Journal of Fish Biology, 2021
AbstractLarval attachment organs (LAOs) are unicellular or multicellular organs that allow larvae to adhere to a substrate before yolk‐sac absorption and the free‐swimming stage. This study documents the LAO of tropical gar, Atractosteus tropicus, using a combination of scanning electron microscopy and light microscopy.
