The green turtle has the most numerous and widely dispersed nesting sites of the seven species, and was once highly sought after for its body fat – a key ingredient in the popular delicacy, ‘green turtle soup.’ Although it has become illegal to trade them in many parts of the world, green turtles and their eggs continue to be consumed.
Nesting areas throughout tropical regions are often on islands and coral atolls in addition to mainland beaches

Green turtles were important for European explorers to the New World; they provided an essential source of food, and they helped crews navigate around islands at night by the increased volume of their aggregated breathing
The former abundance of green turtles in the Caribbean is estimated to have been as high as 500 million individuals
Eastern Pacific green turtles are termed ‘black turtles’ because of their darker coloration. They tend to be smaller and to lay fewer eggs than green turtles elsewhere.
Green turtles nest in highly diverse types of habitats, including archipelagoes, isolated coral atolls, mainland beaches, in all tropical and sub-tropical oceans
