Leatherback. There are at least two types of sea turtles found in the Steps and Tres Palmas area, including Hawksbill and Leatherback. Here we show that egg and hatchling mortality of leatherback turtles (Dermochelys coriacea) in northwest Costa Rica were affected by climatic variability (precipitation and air temperature) driven by the El Niño Southern Oscillation . Your symbolic adoption protects hatchlings and their nests from immediate threats such as predation, tidal inundation, and illegal harvest. Leatherback hatchlings take around 53 days to hatch from their eggs. The Leatherback hatchling uses an 'egg tooth' - a special tooth-like growth on the end of its beak - to break out of its egg. Hatchlings from certain nests have slower righting response times along with slower crawl times, both of which . 2011), typically Whereas hatchling mass increased significantly with egg mass (n = 218 clutches), hatchling mass increased by only approximately 2 g for each 10 g increase in egg mass and was approximately 10-20 g greater than yolk mass.
