Ocular morphology of the Leatherback sea turtle (Dermochelys coriacea).
OBJECTIVE The Leatherback sea turtle is the largest extant reptile and the sole member of the family Dermochelyidae. Here, the eye of this critically endangered marine turtle was investigated to determine the anatomy, optics, and optical sensitivity. ANIMALS STUDIED Three Leatherback sea turtles, Dermochelys coriacea. RESULTS The eye is small in proportion to body size of the adult compared...
متن کاملThe leatherback turtle, Dermochelys coriacea, exhibits both polyandry and polygyny.
The leatherback turtle (Dermochelys coriacea) is an endangered species, and world-wide populations are declining. To understand better the mating structure of this pelagic and fragile species, we investigated paternity in nearly 1000 hatchlings from Playa Grande in Parque Marino Nacional Las Baulas, Costa Rica. We collected DNA samples from 36 adult female leatherbacks and assessed allele frequ...
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...

متن کاملFat head: an analysis of head and neck insulation in the leatherback turtle (Dermochelys coriacea).
Adult leatherback turtles are gigantothermic/endothermic when foraging in cool temperate waters, maintaining a core body temperature within the main body cavity of ca. 25 degrees C despite encountering surface temperatures of ca. 15 degrees C and temperatures as low as 0.4 degrees C during dives. Leatherbacks also eat very large quantities of cold, gelatinous prey (medusae and pyrosomas). We hy...
