Leatherback sea turtle hatchlings, as with other turtle species, face immense danger when emerging from their nests located on the sandy Playa Grande beach in northwest Costa Rica, where nearly forty percent of the nests are burrowed.

Climate variability associated with El Niño was associated with higher mortality for eggs and hatchlings of the critically endangered leatherback turtle, an effect that could be worsened by continuing global climate change.

The movement patterns of critically endangered leatherback turtles vary greatly depending on whether the animals live in the North Atlantic or the Eastern Pacific, with implications for feeding behavior and population recovery.

A new study provides insight into exactly how young loggerhead turtles complete a transoceanic migration that involves moving through the entirety of the North Atlantic basin.

The majestic leatherback turtle is the largest sea turtle in the world, growing to more than 6 feet in length. It is also one of the most threatened. A major new study of migration patterns has identified high-use areas—potential danger zones--in the Pacific Ocean for this critically endangered species.
