This study investigated the sex ratio of leatherback turtle hatchlings along the Huon Coast, Papua New Guinea, from January to March 2007.

The long-term decline of leatherback nesting along the Huon Coast, in conjunction with the highly male-biased sex ratio, presents serious challenges for the management and recovery of the western Pacific leatherback meta-population.
