Green sea turtles are considered large, with adults typically ranging from 1.0 to 1.5 meters (3.3 to 4.9 feet) in length. They generally weigh between 110 to 190 kilograms (240 to 420 pounds), although some can grow larger, up to 220 kilograms (485 pounds).They have a smooth, heart-shaped, and relatively large shell that is usually olive or dark green in color, with shades of brown. This is where they get their name: the "green" refers not to the color of their shell, but to the greenish hue of their fat, which results from their herbivorous diet of sea grasses and algae.Their head is relatively small compared to the size of their body, with a narrow, beak-like mouth that is adapted for grazing. Green sea turtles have large, paddle-like flippers, which they use to glide gracefully through the water, making them highly efficient swimmers.
Green sea turtles are found in tropical and subtropical waters around the world. They are commonly seen in coastal habitats, including beaches, shallow lagoons, coral reefs, and seagrass beds, though they can also be found in open ocean waters at times.They are known to nest on sandy beaches, especially in the Pacific, Atlantic, and Indian Oceans, with notable nesting sites in regions like Hawaii, the Great Barrier Reef, and along the coasts of Central and South America.reen sea turtles are highly migratory, with some individuals traveling thousands of kilometers between feeding and nesting sites. They often return to the same beaches where they were born to lay their eggs.
