Abstract

Biometric measurements were taken of 62 newborn giant Amazon river turtles from eight nests translocated to an artificial beach located at the headquarters of the Chico Mendes Institute for Biodiversity Conservation (ICMBio) on the Crixás-Açu River in the state of Goiás, Brazil. After hatching and complete absorption of the vitellus, the newborns were removed and kept on plastic trays identified by nest number. The following measurements were recorded: carapace length (CL) and width (CW), and plastron length (PL) and width (PW), using a pachymeter with 0.10 mm precision. In addition to the measurements, the specimens were weighed on a balance with 1.00 g precision. The following mean values were recorded (in cm): CL (4.73 ± 0.24); CW (4.01 ± 0.29); PL (4.13 ± 0.18); PW (3.17 ± 0.19) and weight (g) (25.9 ± 1.59). The data presented here are the first of their kind for the species in this region and may serve as reference for future studies.
