of embryonic blood proteins, such as fetal hemoglobin. Anatomy of cartilages of the orbitotemporal region are described for E. This synopsis compiles and reviews the available of the loggerhead sea turtle, Caretta caretta (. caretta, representing a novel pattern of development for the posterior orbital cartilage for this species. Raccoons and other animals that prey on the sea turtle eggs have become more common in the last 30 years due to human development. of the analysed unhatched eggs ceased embryonic development at Stage 6. As a result of the pollution of our waterways, eggs have been found to contain harmful chemicals such as insecticides, which can hurt the egg and the developing embryo. Comparisons among suggest that a possible remnant of the dorsal edge of the orbital cartilage remains and represents a portion of the posterior orbital cartilage in C. Phenological shifts, by initiating reproductive events earlier, in response to advanced seasonal warming is one of the most striking effects currently. The event was reported to the sea turtle rescue centre of the Stazione Zoologica. Morphological changes through prehatching ontogeny are described for all dermal and endochondral elements of the skull and jaws, and the sequence of appearance and ossification of these elements are compared with similar data for Chelonia mydas, Natator depressa, and Dermochelys coriacea. ![]() Illustrations and descriptions of the chondrocranium at Stage 25 form the basis of comparison with similar data for the Loggerhead Seaturtle, Caretta caretta. ![]() The embryonic development of the cranium of the Hawksbill Seaturtle ( Eretmochelys imbricata) is described on the basis of cleared and double-stained specimens.
