The feeding mechanism of gars (Ginglymodi : Lepisosteidae) is characterized by cranial elevation and lower jaw rotation but minimal cranial kinesis. Gar jaws have numerous, sharply pointed, elongate teeth for capture of evasive prey. Their mandibles range from relatively short to extremely long depending on the species.

Riboflavin in the eyes of gars (Lepisosteidae)
Canadian Journal of Zoology, 1972Eyes of gars (Lepisosteidae) have a yellow tapetum lucidum containing an as yet uncharacterized yellow pigment. They also contain fairly high levels of riboflavin, about 14 mg/100 g wet weight, which lies in tissues external to the retina and tapetum and which is, therefore, not a tapetal pigment.

A Standardized Procedure for Internal Sex Identification in Lepisosteidae
North American Journal of Fisheries Management, 2001Abstract During population dynamic and reproductive biology research on three species of Lepisosteidae (i.e., alligator gar Lepisosteus spatula (also known as Atractosteus spatula), longnose gar L. osseus, and spotted gar L. oculatus), we determined that misidentification of sex through gross examination of the gonads was probable.

Abstract Scales of the lepisosteid fish † Obaichthys decoratus and † O.? laevis, from the Lower Cretaceous of the Araripe Plateau (Northeast Brazil) resemble those of palaeoniscoid-type, in which a ganoine layer overlies a dentin layer located above a basal plate composed of lamellar bone.

ABSTRACT Gars (Lepisosteidae, Actinopterygii) are reported from Madagascar for the first time, from exposures of the Upper Cretaceous (?Campanian) Maevarano Formation in the Mahajanga Basin, northwestern Madagascar. The material includes relatively common isolated scales, and vertebral centra, teeth, fin rays, and dermal cranial elements, all assigned ...

Parasitology International
A new genus, Cordicestus, is proposed to accommodate proteocephalid tapeworms parasitising gars (Lepisosteiformes: Lepisosteidae) in North and Central America that were previously placed in the polyphyletic genus Proteocephalus Weinland, 1858. The new genus differs from other proteocephalid genera by the particular morphology of the scolex, which is ...
