Habitat

The sea turtle lives in warm open waters and coasts all over the world other than the arctic circle because it is too cold. Some sea turtles like to live near the coasts in shallow water so that they can burrow into the sand. They also swim out into the deep oceans as well. They are born on land, but quickly move to the sea and spend most of the rest of their lives in the sea. Sea turtles hunt for food in coral reefs and other similar places. The sea turtles are endangered. Their habitats are being destroyed and their nesting sites being destroyed as well by climate change.


Movement

When sea turtles are born, they move quickly from their nests on the land into the water using their flippers to move them. “Most sea turtles migrate between foraging and nesting grounds, and seasonally to warmer waters. Often these migrations take them hundreds and even thousands of miles.” (Oceanic Society 1). They move through the water with their strong flippers. Their speed can reach up to 35 miles per hour. Although they swim and spend a lot of time underwater, they have lungs and go up to the surface to get oxygen through their mouths and nostrils. They can be under the ocean for up to two hours without going up to the surface for oxygen. Even though they swim far, when the female is ready to lay her eggs, she almost always goes back to the nesting place and beach where she was born.

Body Covering

The Turtle has never left home cause It goes into it's shell which is it's home when it needs to. But it also has other perks. Sea turtles have hard, but lightweight, body shells that help protect them from predators. Their shells can be grey, green, black and brown. The shell covers both their dorsal and ventral sides. Their heads are too large to fit in their shells. They also have powerful and strong flippers, without any toes, that allow them to move quickly. “Sea turtle mouths and jaws are also shaped differently depending on their particular diet. Greens sea turtles have a beak with finely serrated edges, like the teeth of a saw, which enable them to tear sea grasses and scrape algae off of hard surfaces.” (Ocean Society 1).

Diet

Turtle have a very diverse diet, they are omnivores which means that they eat both meat and plants. But some species just eat plants. The sea turtles diet includes algae, seaweed, sponges and seagrass and crab, fish and shrimp. Some sea turtles eat jellyfish. The sea turtles that eat grasses have the serrated edges like a saw so they can scrape the algae off rocks and tear the grass and seaweed. The sea turtles that eat jellyfish have two pointed teeth so they can tear through the jellyfish. The sea turtles that eat crabs and shrimp have strong jaws so that they can crush the shell. The sea turtles that eat sponges are the turtles that have the beak so they can reach the sponges in the small holes in the coral reefs.

Reproduction

The Sea Turtle Reproduces is sexually with a male and a female. Mating happens every 2 to 4 years, and most of the time happens close to the shore. They swim far distances to mate. Most females return to the beach where they were born to lay their eggs. The female sea turtles go on to the shore to lay her eggs. She first digs a hole in the sand and then lays about 50 to 100 white, leathery eggs. Then she covers the hole up with sand and goes back to the ocean. In 45 to 70 days after the mother turtle lays the eggs, dig their way out of the sand and crawl to the ocean. In the ocean the babies find cover in seaweed beds. About 90% of baby sea turtles are eaten by predators and do not make it.

adaptation

Sea Turtles are almost every where in the ocean except for some places where the water is too cold or too hot. Nearly all species of sea turtles are endangered. They are wanted for their meat, eggs, skin and shells. Also, their habitats are being destroyed by humans. Many sea turtles “die each year from ocean pollution and ingestion or entanglement in marine debris. Marine debris is manmade waste that is directly or indirectly disposed of in oceans, rivers, and other waterways.” (Ocean Society 1). There are also plastic bags in the ocean, and sea turtles mistake the bags and other garbage for food and eat it, which will kill them.
