Abstract

The Trachemys scripta elegans turtle species, which was described by WIED, in 1839, it belongs to the suborder Cryptodira and the Emydidae family, it came up from the Mississippi Valley, United States of America. It is probably the most widespread reptile species worldwide. This study aims to determine the dimensions (thickness, length and width), the mass and volume of their kidneys and establish a correlation between biometric parameters of the left and right kidneys, and those with biometrics body. The kidneys are located in the caudal portion of the coelomic cavity, parallel to the vertebral column, and disposed dorsally on the syntopic organs to them, adhered to the carapace, after the bridge, in close proximity to the oviduct, in females, and testicles, in males. They also have elongated morphology craniocaudalis, rough aspect and brownish. In literature, there is no data concerning to the dimensions, mass and volume of the turtles kidneys, specifically either the Trachemys scripta elegans species, and this is the first study determining such parameters. For most individuals, the variables (mass, volume and size) established correlations, it demonstrates the interdependence of biometric parameters and renal body of the turtle. And even where there was no correlation, the values were very close to the limit set by statistical analysis (|r| > 0.5). Similarly, we observed a significant correlation between the parameters of contralateral and intersex kidneys. So it follows thefore that the biometrical renal values of Trachemys scripta elegans is proportional to the somatometric.
