The Growth of the Slider Turtle, Pseudemys Scripta Elegans

Structure and Growth of the Utricular Macula in the Inner Ear of the Slider Turtle Trachemys scripta

“…When sexual maturity is reached, growth of the turtle decelerates dramatically and reaches a maximum value asymptotically (Moll and Legler 1971) and growth of the UM seems to follow this pattern. In some specimens growth ceases completely (Cagle 1946(Cagle , 1950. Furthermore, repeated observations show that senility often occurs in Trachemys scripta (Cagle 1944).…”

“…One should be cautious when including chronology as a fixed factor correlated to growth since growth patterns in turtles are extremely perplexing. Temperature during and after embryonic development has both direct and indirect effects on growth in turtles (Williamson et al 1989;Rhen and Lang 1999), and other ecological factors such as food availability and quality are key elements in controlling growth (Cagle 1946;Gibbons et al 1981). In general, however, when animals are kept under suitable conditions, the known growth spurt pattern in juvenile turtles (Cagle 1946;Sarnat et al 1981;Limpus and Chaloupka 1997) can be correlated to the number of HCs and the area of the UM, since the area and number of HCs increase from 0.33 mm 2 and~4000 in prehatchlings to 0.5-0.65 mm 2 and~5000-6000 in juveniles.…”

“…According to Senning (1940) and Cagle (1946), amphibians and reptiles exhibit periodic growth, and this temporal pattern is recorded in certain bones. This pattern can also be observed in the epidermal scutes of chelonians (Halliday and Verrell 1988).…”
