Swim speed and movement patterns of gravid leatherback sea turtles (Dermochelys coriacea) at St Croix, US Virgin Islands.
Swim speed, dive behavior and movements were recorded for seven female leatherback sea turtles (Dermochelys coriacea Vandelli 1761) during a single internesting interval near St Croix in the US Virgin Islands. Modal speeds ranged from 0.56 to 0.84 m s(-1), maximum speed range 1.9-2.8 m s(-1). Turtles swam continuously throughout the day and night. There were two swim-speed patterns; the most co...

متن کاملEstimating body mass in the leatherback turtle Dermochelys coriacea
Body mass is a major life history trait and provides a scale for all living processes of organisms. Unfortunately body mass cannot be easily measured for many species, because of the logistical difficulties involved in actually catching and weighing them. This is particularly true for sea turtles which are large vertebrates that spend most of their life at sea. Here we developed a general linea...
