Of all the different species of sea turtles that exist around the world, we can find three that live in the Mediterranean Sea. Those three species are the Loggerhead turtle (Caretta caretta), the Green turtle (Chelonia mydas), and the Leatherback turtle (Dermochelis coeriacea). The most common of these three is the loggerhead turtle which in fact has a stable nesting area in the most eastern part of the Mediterranean.
