Females of G. ernsti are larger than males. Females may attain a straight carapace length of 28.5 cm (11.2 in), but males only grow to a straight carapace length of 13 cm (5.1 in).[1]
DietEdit
The diet of G. ernsti varies according to age and gender. Males and juveniles prey predominately upon insects, but females prey almost entirely upon snails and clams, including the invasive species Corbicula fluminea.[1]
ReproductionEdit
Males of G. ernsti reach sexual maturity at an age of 3–4 years, but females don't reach sexual maturity until an age of 14–19 years. Each sexually mature female lays an average of 4 clutches a year, with an average clutch size of 7 eggs.[1]
