Exponential relationship, as described by Gompertz regression, in male (n = 11) and female (n = 15) walruses between age (y) and total length (cm). Males grew significantly (χ2 = 29.7 p < 0.0001) faster than females, with an absolute growth rate (RG) of 26.9 cm/year for males compared to 26.6 cm/year for females. Males reached asymptote length by age 13 (95% CI: 309.7 to 338.0 cm), and females (95% CI: 255.9 to 296.4 cm) by age 9.8 y
