Green Sea Turtle
Green sea turtles are reptiles. They evolved from ancestors who walked on land and then went back to the sea many million years ago. Turtles are part of a species that are so ancient in standing that they themselves watched dinosaurs become extinct.
Green Sea Turtles are cold blooded, and breathe air. They possess scaly skins and have a hard outer shell like nearly all turtles.
Many land turtles are able to take their heads back into their shells for protection. Sea turtles are unable to do this and their heads will remain out at all times.
The sea turtle has adapted itself to a watery life.
Their shells have evolved and are lighter in weight than those of their cousins who live on land. They have flippers which help them to move through the water very rapidly. Sea turtles can swim at speeds of up to 35 miles per hour for a reasonable distance.
They swim to the surface every few minutes to take a breath and then dive again, but can remain underwater for as long as two hours without taking a breath when they sleep. Their bodies use oxygen in a very efficient way so that they need less oxygen than other animals.
Additionally their muscles and their blood will store large amounts of oxygen which permits them to stay under the water for a lengthy time span. Smaller turtles or infant or juvenile turtles have not yet developed this and must sleep at the surface.
Behind each sea turtles eye is a salt gland that aids them in ridding their bodies of the salt they take in. They will cry great salt tears which rid their bodies of the extra salt they have taken in from the water.
Green sea turtles are given their names from the color of their body fat, which is green due to the algae they ingest.
While adult green sea turtles eat only herbs and vegetation, the juveniles will also eat meat. Jellyfish is a large part of their diet.
Adult sea turtles can weigh in at about 500 pounds.
The life span of sea turtles is still unknown. Some seem to mature and grow very slowly.
Sometimes, they take from 10 to 50 years before they begin to mate.
Sea turtles live in the ocean for most of their adult lives. Females however must enter land to lay the eggs.
Researchers believe they do this in the same place they were born, sometimes traveling as much as a thousand miles to get there.
Mating is usually in the late spring, when the females enter the beach. They do not mate each year, but come ashore as many as five times to make nests and lay eggs when they do mate.
Green Sea Turtles only nest during the night. The female digs a pit and deposits as many as 100 eggs, which are called a clutch.
The eggs feel very much like leather, as she covers them and buries the pit then returns to the sea. She does not guard the nest or return for her young, which take about two months to hatch.
They must then find their way to the ocean and swim for the next day or two. They do not enter land again for another year or more.
Many hatchlings do not reach the ocean. They are eaten by crabs, birds or sharks as they enter.
Only a very few of those which are born survive the trip to the ocean the first time. Green sea turtles are found throughout the world’s oceans and like some other sea turtles are considered endangered species.
Man is the predator which poses the greatest threat to their survival.Find out more about the Green Sea Turtle over at Wikipedia »
please be specific. you have not given enough information which could help the students to make a project file on endangered species.please give the name of the place where they exists.
you are absolutely right. What a horrid oversight.
I will be glad to research that for you and add it to the file in the next day or so.
There are many more endangered animals coming in the next few weeks from the red list.
I will make sure that we include areas and habitat on each of them.
Thanks for your suggestion.
You’ve done great research! I love LOVE sea turtles and i just adopted my first sea turtle last sept.! it’s a good way to donate to conserve these ancient creatures!
Great article!Thank you!
Poor sea turtles! They are endangered and im sorry for them i really want a pet sea turtles. Great article. Remember SAVE THE SEA TURTLE!

I am obsessed with green sea turtles and they need to be saved or we may have over population of fish they are also very important to our habitat.
SAVE THESE POOR CREATURES FROM BECOMING EXTINCT. WE NEED TO TAKE A STAND. IF WE DON’T, IN A TWINKLE OF AN EYE ALL THE ANIMALS WILL BE GONE OFF THE FACE OF THE EARTH.
