Leatherback Sea Turtle Common Name:
The LPRC is currently conducting in-water research on male, female, and juvenile leatherbacks in the northwest Atlantic, with a particular focus on localized movements, migratory patterns, habitat use and foraging ecology. To date, we have followed and received data from 22 leatherback turtles initially tagged and tracked off Cape Cod, MA and off the northern Florida coast, two important foraging grounds.
From tagging data, we can identify what ocean habitats leatherbacks use most, how they get there and back, and where and when they breed and over-winter. With tagging, we can also evaluate the effects of oceanographic conditions such as sea surface temperature and chlorophyll-a a proxy for primary production on leatherback movements, and what cues leatherbacks may use for orientation and navigation during long distance migrations.
From the seminal historic work conducted by Dr.
Sherman Bleakney and Skip Lazell, the New England continental shelf has long been known as a seasonal forage grounds for leatherbacks. Nonetheless, only a few diet studies have been performed, and they relied on stomach content analysis, which has limited utility for identifying gelatinous and rapidly digested prey.
Our findings also offer new insight on size- and sex-related differences in the diet of leatherbacks northwest Atlantic shelf. Health and Population Studies Health threats to all sea turtle species are poorly understood, and this is especially true for leatherback turtles, that are rarely successfully kept in long-term captivity where they can be studied.
SinceLPRC researchers have collaborated with veterinary specialists from the New England Aquarium and the Provincetown Center for Coastal Studies to conduct health evaluations of leatherback sea turtles in order to better understand their baseline health, physiology, and pathology off Massachusetts.
Results from work conducted from — have been reported by Innis et al. Sincethe LPRC has also been collecting DNA samples from leatherback turtles for genetic analysis in order to contribute to a better understanding of their population structure in the Atlantic.The leatherback is the largest turtle in the world.
They are the only species of sea turtle that lack scales and a hard shell and are named for their tough rubbery skin.
Leatherbacks belong to a different taxonomic family than the six other sea turtle species found in the world. They have existed in. Turtle (Dermochelys coriacea) 5-Year Review: Summary and Evaluation. National Marine Fisheries Service, Silver Spring, Maryland and U.S.

Leatherback turtles are named for their shell, which is leather-like rather than hard, like other turtles. They are the largest sea turtle species and also one of the most migratory, crossing both the Atlantic and Pacific Oceans.

A recent global analysis of leatherback turtle hatchling output predicts that the nesting site at Sandy Point National Wildlife Refuge (SPNWR) will experience the most significant regional climate. Turtle Shell While all other sea turtles have hard, bony shells, the inky-blue carapace of the leatherback is somewhat flexible and almost rubbery to the touch. Ridges along the carapace help give.
