The Green Sea Turtle which is popularly known for its hard-shelled body is one of the largest sea turtle in the world. It belongs to the Cheloniidae family and its binomial name is Chelonia mydas.
Green Sea Turtles are often found in the tropical and subtropical seas. They live in warm shallow water as they are cold-blooded animals and can not produce heat inside the body themselves. They’re called by the name Green Sea Turtle due to the fat found in their body under the carapace. They’re reptiles, ancestors of whose utilized to evolve in the land once and went back to the water for living.
They’ve a gorgeous flat carapace which could be of various colours. Green Sea Turtles need oxygen to keep their physical activities functioning. They usually live under the water most of the time of their lifespan but they come on the sea surface to breathe-in oxygen. Their lungs are designed to provide them with the necessary supports which are needed to dive underwater for quite 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 cows to digest herbs.
They pass the majority of their lifespan under the sea but female turtles will need to return to the land to lay eggs. Upon maturity, turtles will need to perform great migration to lay eggs. Usually male turtles don’t accompany the female turtles while laying eggs. They mate the female turtles offshore. Male turtles try to partner every year but female turtles usually mate every two or three years. It takes approximately 60 days to incubate eggs. The newborn turtles can come from the eggs themselves and head to the sea seeing the reflection of moon on the sea water.
This mighty animal generally gets sexually mature at the age of 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 areas. Unplanned tree plantation in the sea shore causes the disturbance in the ratio of the female and male turtles because the sex of turtles are determined by the incubator temperature that may be varied with the color of the trees. Artificial light sources near the sea shore also hamper the proper hatching procedure. Pollution of water causes some acute diseases into the turtles. It creates tumor which results in a disease called fibropapillomatosis. In any case, because of being captured by people and eaten by predators like shark, crab, sea fish, birds, they are becoming extinct day by day.
