Abstract:

Body size measurements were obtained from 53 hatchlings and 276 juvenile to adult hawksbill turtles (Eretmochelys imbricata) at Mona Island, Puerto Rico. Allometric change in the size of body structures were examined by regression analysis. Turtle heads underwent the greatest proportional change, with larger turtles presenting a significantly decreased head width to carapace length ratio. The proportion of carapace width to length remained constant for hawksbill turtle throughout the size range examined. Sexual dimorphism in tail size was observed from 68.2 cm straight-line carapace length. Australian and southern African turtles differ from Caribbean hawksbill turtles in having significantly greater carapace width in proportion to carapace length.
