Presently
several species of marine sea turtles are active with nesting
in the Guiana Shield region. The beachs along the coasts of
Suriname, French Guiana and Guyana are important locations for
the laying of eggs. The GSMP is planning to produce media material
about these ancient and endangered creatures and the conservation
efforts for their protection. The GSMP is working closely with
the Guyana Marine Turtle Conservation Society (GMTCS) and the
WWF . In the near future we will have more reports, stories
and photos as well as documentary programmes.
Brief
Overview
Sea
turtles are large, air-breathing reptiles that inhabit tropical
and subtropical seas throughout the world. Their shells consist
of an upper part (carapace) and a lower section (plastron).
Hard scales (or scutes) cover all but the leatherback, and the
number and arrangement of these scutes can be used to determine
the species.
Sea turtles do not have teeth, but their jaws have modified
"beaks" suited to their particular diet. They do not have visible
ears but have eardrums covered by skin. They hear best at low
frequencies, and their sense of smell is excellent. Their vision
underwater is good, but they are nearsighted out of water. Their
streamlined bodies and large flippers make them remarkably adapted
to life at sea. However, sea turtles maintain close ties to
land.
Females
must come ashore to lay their eggs in the sand; therefore, all
sea turtles begin their lives as tiny hatchlings on land. Research
on marine turtles has uncovered many facts about these ancient
creatures. Most of this research has been focused on nesting
females and hatchlings emerging from the nest, largely because
they are the easiest to find and study.
Thousands of sea turtles around the world have been tagged to
help collect information about their growth rates, reproductive
cycles and migration routes. After decades of studying sea turtles,
much has been learned. However, many mysteries still remain.
