Six adult (three female and three male) leopard tortoises (Testudo pardalis) were stud ied to document the radiographie anatomy of the gastrointestinal tract and the transit time of barium sulfate. Tortoises were chemically immobilized with succinylcholine and dosed orally with barium contrast suspension. Both dorsoventral and lateral radiographs were taken. The lateral radiographs were extremely difficult to interpret because of the overlapping of the gastrointestinal tract and other soft tissue organs. Complete gastric emptying occurred between 5 and 9 hr after barium administration. Barium entered the small intestine at 0.2-1 hr and the large intestine between 5 and 8 hr. The contrast material began to exit the colon between 144 and 166 hr.
