Sea turtles are reptiles.
They lay eggs.
They breath air just like you and me.
Different sea turtles can weigh from 100 to 1300 pounds!
They are one of the few reptiles that depend on the sea to survive.
Carapace- harder outer covering or upper part of turtle shell.
Carnivore- animal that eats other animals
Coastline - the outline or shape of a coast.
Endangered Species - a type of animal or plant in danger of becoming extinct.
Habitat - a type of area/environment in which an animal normally lives.
Herbivore- an animal that only feeds on plants.
Life Span - the length of time that a human, animal, or plant lives or can be expected to live.
Migratory or migration - to move from one area to another.
Ominvore - an animal that lives on a diet of both plant and animal food.
Poached- to hunt, fish, or trap illegally.
Reptile- cold-blooded air breathing animal with a backbone.
Species - a group of animals or plants that are the same type.
Vunerable - able to be hurt or injured.
Dark blue areas show where a Loggerhead sea turtle may live.
Loggerhead turtles are the most abundant sea turtle in the United States. They got their name for their really large head. They have been an endangered species list since 1978.
The Loggerhead has long flippers and specialized glands that help it drink the salty sea water.
Loggerhead's are carnivores. They eat jellyfish, conchs, crabs, and fish.

Interesting Facts
Sea turtles can swim at speeds of up to 15 miles per hour.
For some sea turtles it takes 20 to 50 year before a female sea turtle can lay eggs.
Unlike other turtles, sea turtles can not retract into their shells
Most sea turtles warm themselves by going close to the surface however, the green turtle has been known to go to shore to sunbathe.
The upper part or back a sea turtle is called a carapace.
Sea turtles do not have teeth except a single tooth that they have at birth to help them out of their shell and to the ocean called a caruncle.
Dark blue areas show where a Green sea turtle may live.
Green Sea Turtles do not actually have a green shell. Their shell is normally brown or olive in color depending on their habitat. They are called Green Turtle because the green color of their skin. The Green Turtle is also called the black turtle.
Their heart shaped shell can grow to be up to five feet and they can weigh up to 700 pounds.
Each green turtle has specific features that make them easy to recognize. These features are like their fingerprints.
Green Turtles

Green Sea Turtles are the most widespread. They are found near 139 countries.
They like the Loggerhead have also been on the endangered species list since 1978.
Adult Green Turtles are herbivores. They eat mostly sea grasses and algae. Baby Green turtles are omnivores and will eat jellyfish, mollusks, and sponges.
Also like the Loggerheads, Green Sea Turtles will travel thousands of miles and lay up to 150 eggs.
Dark blue areas show where a Leatherback sea turtle may live.
Leatherbacks are the largest turtle on Earth. They can grow to be up to seven feet long and 2000 pounds. It is also the only sea turtle without a shell. Leatherbacks carapace or shell area is brownish-black and is somewhat flexible and rubbery.
Leatherbacks are carnivores and eat mainly jellyfish and other ocean drifters. They can up eat to 1,000 pounds of food in one day.
Leatherback
They are able to dive deeper than any other turtle, up to 4,200 feet. They also are able to swim in colder water as a result of adaptations like their greater body fat.
They travel the greatest distance to lay their eggs sometimes up to 3,700 miles. Female Leatherbacks are able to lay eggs anywhere from 8-15 years old. They can lay up to 180 eggs in one nest.
The Leatherback has been listed as endangered species list since 1970.
Hawksbill
Where does the Hawksbill live?
Hawksbill
Dark blue areas show where a Hawksbill

Average Life Span
Loggerhead live for more than 50 years
Green Turtles can live up to 80 years.
Leatherback live up to 45 years.
Hawksbill can live anywhere from 30 to 50 years.
Kemp's Riley and Olive Rile live to be about 50 years old.
Little research has been done on the flatback and an average life span is unknown.
Hawksbill got their name because they have a similar slender body, head, and narrow beak as a hawk. They are small compared to other turtles growing up to only 45 inches and 150 pounds. They are said to have the most beautiful shell that is colored reddish or dark brown with males tending to be brighter than females. Another unique feature they have is the pair of claws on their flippers.
Loggerhead

They have a reddish brown hard shell. They can grow to be up to four feet in length and weight up to 250 pounds.
They will travel for thousands of miles to lay their eggs on the same beach they hatched on. They can lay up to 120 egss in a nest.
The Hawksbill is a carnivore and eats sponges, jellyfish, starfish, fish, urchins, and crustaceans.
Unlike the leatherback the Hawksbills stay away from deep waters and stick close to the coastline. Females can lay up to 160 eggs in one nest.
The Hawksbill is an internationally recognized endangered species and has been the on United States endangered species list since 1970. They are often poached for their beautiful shells.
Kemp's Ridley
Kemp's Ridley sea turtles are the smallest of the sea turtles only growing up to 2 feet and 100 pounds. They have an oval or heart shaped shell that is greenish gray.
Kemp's Ridley sea turtles are onimvores and eat crabs, fish and shrimp. They also will occasionally eat seaweed and sargassum.
Kemp's Ridley
The Kemp's Ridley was also placed endangered species list in 1970 and is the most endangered sea turtle. 50 years ago there were 40,000 nests compared to 2,500 today. Kemp's Ridley can lay up to 100 eggs in each nest. The Kemp's Ridley nest differently than the other sea turtles. They meet at the edge of the water and all come out at the same time a process called arribada (which means arrival in Spanish).
Where do Kemp's
Ridley live?
Where does the Olive Ridley live?
Olive Ridley
Also similar to the Kemp's Ridley the Olive Ridley is the smallest of the sea turtles also growing up to two feet and weighing up to 100 pounds.
The Olive Ridley is an omnivore and eats lobsters, fish, crustaceans, mollusks, algae, fish eggs and jellyfish. They will occasionally eat seaweed and algae.
Olive Ridley
Olive Ridley turtles are also an endangered species however they are the most abundant of the endangered sea turtles. They remain endangered because they have very few nesting sites left.
They tend to be solitary and prefer the open waters of the ocean. They spend their entire lives in the ocean only coming to shore to nest. Similar to the Kemp's Ridley they congregate at the edge of the water and come to shore together. Where they also lay up to 100 eggs.
Dark blue areas show where a Kemp's Ridley
sea turtle may live.

Flatback
Flatback sea turtles get their name because instead of having a rounded shell their shell is flat. The Flatback sea turtle grows to be a little over three feet and can weigh up to 200 pounds. The Flatback is found around Austrailia and has been recognized as vulnerable in Australia since 1992.
The Flatbacks are the least migratory of the sea turtle species. They tend to live inshore, in bays, and shallow sea beds.
Flatback
Flatback sea turtles are omnivores and eat sea cucumbers, jellyfish, prawns, bryozoans, and seaweed.
When they nest they lay up to 50 eggs, the smallest amount of any sea turtle. The hatchlings are known to be beautiful with black outlining and blue eyes.

Major threats to the sea turtle population come from commercial fishing where the sea turtles get caught in nets intended for other fish.
Poaching is also a problem of adult sea turtles for their meat and shells. There are also some who will take the eggs as well.
Ocean pollution is also a problem, sea turtles will eat plastic bags thinking they are a jellyfish.
Development and destruction of the sea turtles nesting areas are also threatening the turtles. This leaves the turtles with no place to lay their eggs.
There are many protection laws for sea turtles and in some places the number of sea turtles are going up!
What you can do...
Donate money to a conservation group
Stop using plastic bags
Educate people about endangered species.

Danielle Wentworth lives in Ashland, Ohio with her family. She is married and has two children. She is currently a student at Ashland University where she is working to obtain her teaching license. She has always liked sea turtles and believes they are beautiful creatures.
Kindergarten:
LS- Living things have physical traits and behaviors, which influence their survival.
First grade:
LS- Living things have basic needs, which are met by obtaining materials from the physical environment.
Living things survive only in environments that meet their needs.
Second grade:
LS- Living things cause changes on Earth.
Third Grade:
LS- Offspring resemble their parents and each other.
Individuals of the same kind differ in their traits and sometimes the differences give individuals an advantage in surviving and reproducing.
Plants and animals have life cycles that are part of their adaptations for survival in their natural environments.

I learned a great deal doing this project. It is a different approach to presenting material to children. I also like how you can control what information they get and to make sure it is grade level appropriate. I have always enjoyed sea turtles and learned a great deal myself throughout this project.
