	Females	Males
Carapace length (mm) (Range)	100.4 ± 5.5 (89.3–112.1)	115.3 ± 5.9 (102.7–128.1)
Age (Yr) (Range)	27.5 ± 11.6 (11–58)	21.0 ± 10.2 (9–55)
Median Lifespan (Yr) (Age x, 50% of adults alive)	22.6	19.4
Maximum Lifespan (Yr) (Age x, 5% of adults alive)	42.4	35.6
Initial adult mortality rate (IMR) (95% Credible Interval)	0.05 (0.04–0.053)	0.07 (0.06–0.08)
Rate of Ageing (RoA) (95% Credible Interval)	0.041 (0.003–0.05)	0.043 (0.003–0.056)
Mortality rate doubling time (Yrs)	16.1	16.9

Mean adult body size and age ± 1 SD for the N = 102 females and N = 98 males included in the immune measures (above the bold line). Below the bold line, for the entire sample of N = 1530 female and N = 860 marked animals in this population, median and maximum adult lifespan (age x at which 50 and 5% adults remain alive, respectively); ageing parameters obtained by fitting Gompertz accelerating mortality model of the age-specific mortalities: u_x = Ae^bx where A is the initial adult mortality rate (IMR) modeled at age 11 years for both sexes and b is the rate of accelerating mortality (Rate of Ageing, RoA); and Mortality rate doubling time (Ln(2)/b)
