HIRTH, H.F. 1978. A model of the evolution of green turtle (Chelonia mydas) remigrations. Herpetologica, 34, 141-147.

(Speculations on how long-distance remigrations evolved...perhaps through a stage of passive drift).

(initial travel paths of hatchlings are roughly at right-angles to beaches; paths do not change when land is out of sight at turtle eye level).

(3 out of 4 hatchlings survived in captivity for at least 249 days; cooler water may have helped reduce swimming against sides of tank; chicken liver diet used).
