Turtles have been around for 95 million years. Their ancestors were
giant land turtles that entered the sea ages ago when the great
dinosaurs lived. The first sea turtles looked little like those of
today. It took millions of years for sea turtles to change, for legs to
become pad-shaped flippers and for heavy, bulky bodies to flatten into
lighter, streamlined shapes. The dinosaurs and the giant land turtles
are gone forever; we can see only their fossil bones in museums. But,
somehow, sea turtles have lived on.
Seven different kinds still swim in warm and temperate oceans around the
world. They spend their whole lives in the water except for the brief
times the females come onto land to nest and lay their eggs. The sea
turtles share the sea with fish, whales, other sea creatures and you and
me. In the seas surrounding Turkey, two species of sea turtles live:
Loggerheads (Caretta caretta) and Green Turtles (Chelonia mydas).
