Notes:
H = hatchlings; PJ = pelagic juvenile; BJ = benthic juvenile; and A = adult. H–A represents age at sexual maturity. For H–A or H–PJ, the size distribution
denotes the range in sizes for which the authors considered turtles to be adults or to be at the end of the pelagic stage. Otherwise, the size distribution is the range
in size for which duration has been estimated. Captive growth rates are not included.
a
Indicates actual number of turtles in study; some studies used multiple recaptures of the same turtle as additional data points.
b
Results were extrapolated beyond the range of the data.
c
Number of growth records used, actual number of turtles not reported.
d
Animals from this study were kept in captivity for first year, then released as part of the head-start program for Kemp’s ridleys.
