Table 2. Sex ratios of different life stages (hatchling, immature, and adult) of green turtles at various locations worldwide.

Hatchling sex ratios are from nesting beaches while immature and adult sex ratios are from foraging grounds. NA: not applicable. CCL: curved carapace length. *: 1,199 turtles sexed, but number of turtles for each life stage was not provided.
