The ecology of Chelonia mydas changes drastically with each stage of its life history. Newly emerged hatchlings are carnivorous, pelagic organisms, part of the open ocean mini-nekton. In contrast, immature juveniles and adults are commonly found in seagrass meadows closer inshore as herbivorous grazers (Wikipedia). Habitat Green sea turtles move across three habitat types, depending on their life stage. They lay eggs on beaches. Mature turtles spend most of their time in shallow, coastal waters with lush seagrass beds. Adults frequent inshore bays, lagoons and shoals with lush seagrass meadows. Entire generations often migrate between one pair of feeding and nesting areas (Wikipedia). Turtles spend most of their first five years in convergence zones within the bare open ocean that surround them. These young turtles are rarely seen as they swim in deep, pelagic waters. Green sea turtles typically swim at 2.5–3 km/h (1.6– 1.9 mph) (Wikipedia). Gazelle : The Palestinian Biological Bulletin – Number 149 – May 2017
