Core Questions

How is the ocean animal suited for its current environment?

They are very good swimmers due to there flippers. They have paddle like flippers which helps them move gracefully throughout the water. And since they are cold-blooded they can stay underwater for a long time.They can stay underwater for 5 hours without coming to the surface. There limbs are non retractable and there she'll is smooth which helps them glide.

How have humans impacted the environment of the ocean animal?

Humans have ruined turtles beaches for nesting by coastal development. This has made many sea turtles have to find different beaches for nesting and different areas to eat since most of there food supply has been destroyed as well. Also pollution from coasts has also not helped the green sea turtles.They have also killed them for meat and eggs. Boat propellers and fish net catching and drowning them have killed them.

What is the future of this ocean animal? And how do you know?

The future of the green sea turtle is not looking good. They are endangered from things humans have done. If humans do not stop destroying their habitat they could go extinct. I know this from one of many of my resources like "Green Turtle." World Wildlife Fund, n.d. Web. 06 Feb. 2015. And "Green Sea Turtle - National Wildlife Federation." Green Sea Turtle - National Wildlife Federation. N.p., n.d. Web. 02 Feb. 2015., that talk about the threats that are happening to sea turtles by humans. If we don't take action now this animal could go extinct.
