Chelonia mydas
Usually 80 to 120 cm in shell length, reaching a maximum of around 150 cm.
From 0 to over 50 metres, most commonly found in shallow coastal waters.
Adults feed primarily on seagrass and algae, while juveniles also consume small invertebrates.
Usually solitary, regularly surfacing to breathe.
Regularly encountered, particularly along the east coast of Cyprus.
Currently listed as "Least Concern" globally (IUCN), but still strictly protected regionally and locally threatened in parts of its range.
Native species and an important nesting species in the eastern Mediterranean.
The Green Sea Turtle (Chelonia mydas) is one of the most iconic marine animals found in Cyprus. It is the world's largest herbivorous sea turtle and is regularly observed at dive sites such as Green Bay near Protaras. Cyprus is considered one of the most important nesting areas for this species in the Mediterranean.
Where to Find in Cyprus: Dive Sites & Habitat
Cyprus is one of the most important breeding areas for the Green Sea Turtle (Chelonia mydas) in the Mediterranean. The turtles use both protected nesting beaches and the island’s coastal seagrass meadows as feeding grounds. Areas with extensive growth of Cymodocea nodosa are particularly important, as this seagrass forms a significant part of their diet.
In the past, Green Bay near Protaras was considered one of the most reliable locations for sea turtle sightings. In recent years, however, the number of encounters has declined noticeably. One of the main reasons is the illegal feeding of sea turtles by excursion and tourist boats. This causes the animals to lose their natural wariness and spend more time at the surface near boats, significantly increasing the risk of collisions with vessels and propeller injuries.
Through Project Xenios, Cyprus Diving Centre has been systematically documenting sea turtle sightings in the region for several years. The collected data helps improve understanding of local population trends and allows changes in sighting frequency to be identified at an early stage. The Green Sea Turtle remains one of the most characteristic inhabitants of Cyprus' coastal waters, although sightings are no longer as frequent as they were a few years ago.
Behavior & Key Features Underwater
The Green Sea Turtle (Chelonia mydas) is the only sea turtle species that feeds primarily on plants as an adult. It grazes seagrass meadows much like an "underwater lawnmower", playing a vital role in maintaining the health of these important ecosystems. Females undertake remarkable migrations, sometimes travelling several thousand kilometres before returning to the very beaches where they hatched to lay their own eggs. Scientists believe that they navigate, at least in part, by using the Earth's magnetic field.
For divers, snorkellers, and swimmers, it is important to remember that sea turtles should never be fed, touched, or chased.
In Cyprus, the feeding of turtles by tourist and excursion boats has become a serious issue. As a result, turtles lose their natural wariness and spend more time near the surface, significantly increasing the risk of collisions with boats and injuries from propellers. We have also observed cases in which sea turtles became more aggressive towards people as a consequence of such interactions.
Frequently asked Questions (FAQ)
Where can you see Green Sea Turtles in Cyprus?
Your best chances are at Green Bay near Protaras and other coastal areas with seagrass meadows. Green Sea Turtles are particularly attracted to these habitats because they provide important feeding grounds.
What does the Green Sea Turtle eat?
Adult Green Sea Turtles feed mainly on seagrass and algae. As a result, they play an important role in maintaining healthy coastal ecosystems.
Why should sea turtles not be fed?
Feeding causes sea turtles to lose their natural wariness of boats. They spend more time near the surface and around vessels, which significantly increases the risk of injuries from boat propellers and collisions.
