The Earth is made up of 71% water, of which the sea and oceans occupy 96.5%. The ocean plays a significant role in regulating the Earth's climate and supports much marine life such as sharks, whales, jellyfish and sea turtles. Sea turtles are recognized as ancient animals that have existed for more than 100 million years since the time of the dinosaurs. Sea turtle is the public name of the sea turtle that includes the super family Chelonioidea. It is a large marine reptile with a bony or leathery shell, large upper eyelids, a non-retractable head and powerful front fins (Lim & Das, 1999). Sea turtles are part of the marine life that can help maintain a healthy marine food web and are responsible for recycling nutrients from oceans to beaches, especially during the nesting season, to support vegetation as well as prevent erosion. According to Spellman (2008), the five common species of sea turtles are the leatherback turtle (Dermochelys coriacea), the Kemp's ridley turtle (Lepidochelys kempii), the green turtle (Chelonia mydas), the hawksbill turtle (Eretmochelys imbricata), and the Loggerhead (Caretta caretta). ) (refer to Figure 1 in Appendix 1). The first type of sea turtle is Dermochelys coriacea. According to Gulko and Eckert (2004), it is the only living representative of the Dermocheyldae family. Dermochelys coriacea is the largest sea turtle, commonly known as the leatherback turtle. It has the widest global range. It is widespread in all oceans except the Antarctic and the Arctic. The shell length of the leatherback turtle is approximately 178 cm and it weighs from 250 kg to 907 kg. A male turtle sometimes reaches a shell length of 6.5 feet, or 198 cm, and weighs up to 907 kg. They get their name from their shell. Leatherback turtles are... center of paper... er, L., & Heppell, S. (2011).
