It belongs to the Cheloniidae family and its domain is Chelonia mydas.
Green Sea Turtles are usually found in the tropical and subtropical seas. They are called by the name Green Sea Turtle because of the fat found in their body under the carapace. They are reptiles, ancestors of whose used to evolve in the land once and went back into the water for living.
This gorgeous creature can weigh up to 200 kilograms and grow 4-5 feet long. They have a gorgeous flat carapace which can be of various colours. Green Sea Turtles need oxygen to keep their physical activities functioning. They generally live under the water the majority of the time of their lifespan but they come on the sea surface to breathe-in oxygen. Their lungs are designed to give them the necessary supports which are required to dive underwater for a long time. They have two large flippers which enables them to swim at the rate of 35 mph.
Juvenile Turtles are omnivorous and adults are often herbivorous. They have the same enzyme as cattle to digest herbs. But adult green sea turtles have rarely been observed in the wild to know their food habit.
They pass most of their lifespan under the sea but female turtles need to come back to the land to lay eggs. Upon maturity, turtles will need to perform great migration to lay eggs. Usually male turtles do not accompany the female turtles while laying eggs. They mate the female turtles abroad. Male turtles try to partner each year but female turtles generally mate every two or three decades. It takes about 60 days to incubate eggs. The newborn turtles can come from the eggs and head towards the sea visiting the reflection of moon on the sea water.
This powerful animal usually gets sexually mature at age 25 and can live up to 80 years in the wild.
This species has been endangered by numerous natural and human generated reasons. Erosion of sea-beaches and reclamation of sea lands hurt their nesting places. Unplanned tree plantation in the sea beach causes the disturbance in the ratio of the female and male turtles as the sex of turtles are determined by the incubator temperature which can be varied with the shade of the trees. Artificial light sources near the sea shore also hamper the proper hatching process. Pollution of water causes some severe diseases into the turtles. It creates tumor which results in a disease known as fibropapillomatosis. In any case, because of being caught by people and eaten by predators like shark, crab, sea fish, birds, they are getting extinct day by day.
