Restore to good health in baby turtle, Trachemys scripta elegans with chronic anorexia and blind eyes

As the first case, a baby red eared slider turtle, Trachemys scripta elegans, 1.77 inches long, with a 4 month history of anorexia and blind eyes was referred to the Aquatic Animal Clinic, School of Veterinary Medicine, Shiraz University, Iran. The eyes of the pet were swollen and he was not active in swimming and feeling around. In the clinic, after stress treatment, he was kept in a clean aqu...

Phallus development in the turtle Trachemys scripta.

Development of a phallus occurs in almost all amniotes; however, considerable variation in phallus morphology among different amniote lineages has contributed to the debate about their structural homology. Mammals are the only amniotes that form a closed urethral tube within the penis. In contrast, the phallus of reptiles and birds has an open urethral groove, or sulcus spermaticus, that facili...

Radial glia in the proliferative ventricular zone of the embryonic and adult turtle, Trachemys scripta elegans

To better understand the role of radial glial (RG) cells in the evolution of the mammalian cerebral cortex, we investigated the role of RG cells in the dorsal cortex and dorsal ventricular ridge of the turtle, Trachemys scripta elegans. Unlike mammals, the glial architecture of adult reptile consists mainly of ependymoradial glia, which share features with mammalian RG cells, and which may cont...

Morphological and mechanical changes in juvenile red-eared slider turtle (Trachemys scripta elegans) shells during ontogeny.

Turtles experience numerous modifications in the morphological, physiological, and mechanical characteristics of their shells through ontogeny. Although a general picture is available of the nature of these modifications, few quantitative studies have been conducted on changes in turtle shell shape through ontogeny, and none on changes in strength or rigidity. This study investigates the morpho...

Red-eared slider turtles (Trachemys scripta elegans)

Photoreceptors and visual pigments in the red-eared turtle, Trachemys scripta elegans.

Absorbance spectra of cone outer segments and oil droplets were recorded microspectrophotometrically in the retina of the red-eared turtle, Trachemys scripta elegans. There are four cone visual pigments, with lambda(max) = 617 nm (red sensitive), 515 nm (green sensitive), 458 nm (blue sensitive), and 372 nm (UV-sensitive). The red-sensitive pigment resides in single cones with red or orange oil...
