| Abstract |
|
Malaclemys terrapin Hatchling diamondback terrapins were studied in 1974 on Little Beach Island, New Jersey . Of the nests studied 36%, were not destroyed by predators during the incubation period and 69% of the eggs in these nests hatched, and 76% of the hatchlings emerged successfully. Hatchlings in individual nests emerged over a 1-8 day period, and most hatchlings emerged during the day. Hatchlings emerging from nests on flat sand areas showed no compass orientation, while those emerging on sloping dunes moved downward. Results of tests on an incline apparatus were consistent with field observations. Hatchlings emerging from nests on flat areas moved directly to the closest vegetation. Results of tests indicated a preference for the nearest grass clump. Hatchlings tested on an incline apparatus moved to the vegetation regardless of the direction of the slope.
