There are two species of marine turtles that that are commonly found in the Red Sea: the Hawksbill and the Green Turtle.
You can read more about how to know the two species from each other in this blog post .
You can help in gathering information about their distribution and life cycle, if you send your pictures to TurtleWatch Egypt – which we strongly support. Any information is useful, but you can learn more about identifying individuals here.
You can download a catalogue (a pdf – available at the end of the blog post) with more than 70 individual Green turtles – absolutely free.
