Green Sea Turtle Latest News

The carcass of a green sea turtle washed ashore on Marina beach in Chennai recently.

It is the largest hard-shelled sea turtle.
Scientific Name: Chelonia mydas
They are unique among sea turtles in that they are herbivores, eating mostly seagrasses and algae.
This diet is what gives their fat a greenish color (not their shells), which is where their name comes from.

Green turtles are found throughout the world, mainly in tropical and subtropical waters.
These turtles are found nesting along the coastline of more than 80 countries, with the largest nesting populations found in Costa Rica and Australia.
Similar to other sea turtles, green sea turtles migrate long distances between their feeding grounds and their nesting sites, with recorded distances longer than 1,615 miles (2,600 kilometers).

They are large in size, attaining about 120 cm in length and weighing about 136-159 kg.
They have a comparatively small head.
The green turtle has a smooth carapace which varies in shape, between sub-circular and heart-shaped, and in colouration between black, grey, green, brown, and yellow. The plastron (bottom shell) is yellowish-white in colour.
They 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.
Lifespan: Estimated to be 60-70 years.
