Post your questions or anything interesting that you have about the green turtle here and let your friends comment on them. Let's build our knowledge on the green turtle.
Total there are seven types of sea turtle in our ocean. Grean sea turtles are reptiles. Their ancestor lived about 150 milions years ago. They are one of the few species that remains after the dinosaurs period. They are cold-blooded, meaning that they get theirbody heat from the environment rather than making their own. The shel also called 'carapace' covers both the dorsal( back ) and ventral ( belly ) surfaces and is considered the most highly devoloped protective armor of any vertebrate species ever lived. When sleeping or resting, which usually occurs at night,adult sea turtles can remain underwater for more than two hours without breathing. This is due to the fact that turtles are capable of containing higher concentrations of carbon dioxide in their blood than most other air-breathing animals, enabling them to use their oxygen very .efficiently
Singapore goverment did not allow turtle eggs from other countries because we will get fined. When I go to Tanjung Pinang I saw singaporeans buying and eating turtle eggs. They are not helping to save the turtles from extinction.
The Green sea turtle (Chelonia mydas), also known as green turtle, black (sea) turtle, or Pacific green turtle,[3] is a large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia.[4] Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans.[5] Their common name derives from the usually green fat found beneath their carapace (upper shell).
The green sea turtle is a sea turtle, possessing a dorsoventrally flattened body covered by a large, teardrop-shaped carapace and a pair of large, paddle-like flippers. It is usually lightly colored, although parts of the carapace can be almost black in the eastern Pacific. Unlike other members of its family, such as the hawksbill sea turtle and loggerhead sea turtle, C. mydas is mostly herbivorous. The adults commonly inhabit shallow lagoons, feeding mostly on various species of seagrasses.[6]
Like other sea turtles, they migrate long distances between feeding grounds and hatching beaches. Many islands worldwide are known as Turtle Island due to green sea turtles nesting on their beaches. Females crawl out on beaches, dig nests and lay eggs during the night. Later, hatchlings emerge and walk into the water. Those that reach maturity may live to age 80 in the wild.[5]
C. mydas is listed as endangered by the IUCN and CITES and is protected from exploitation in most countries. It is illegal to collect, harm or kill them. In addition, many countries have laws and ordinances to protect nesting areas. However, turtles are still in danger because of several human practices. In some countries, turtles and their eggs are hunted for food. Pollution indirectly harms turtles at both population and individual scales. Many turtles die caught in fishing nets. Also, real estate development often causes habitat loss by eliminating nesting beaches.
