Turtles & TortoisesBy Mrs. Hickey3rd GradeTurtle & Tortoise Fun FactsTurtles have been on the earth for more than 200 million years. The earliest turtles had teeth and could not retract their heads.Several species of turtles can live to be over a hundred years of age. Turtles live on every continent except Antarctica. Turtles range in size from the 4-inch to the 1500-pounds. The shell of a turtle is made up of 60 different bones all connected together. Most turtle species have five toes on each limb.Turtles have good eyesight and an excellent sense of smell. Hearing and sense of touch are both good and even the shell contains nerve endings. Turtles are one of the oldest groups of reptiles and have outlived many other species.

The southeastern United States includes one of the worlds richest regions for freshwater turtle diversity. Fresh Water Turtles
Fresh Water Turtle HabitatsMost are found in rivers, reservoirs, ponds, and small lakesMost often, chicken turtles chose an older live oak and pine forest for wintering habitatSpiny softshell turtles live in riverine habitats where they often bask on sandbars and bury in clean sand in the river bottoms

Fresh Water Turtles FoodCommon Snapping Turtles can sniff out dead animals, which they add to their diet of plants, small birds and fishYellow bellied and River cooters eat insects and other aquatic invertebrates, and plantsSoftshells mostly eat meat including crayfish, fishes, and insects that live in the water, also acorns and leavesChicken Turtles are omnivorous, eating crayfish, fish, fruits, insects, invertebrates, frogs, tadpoles and plants

Land Turtle (tortoise) HabitatsBox turtle live in open woodlands and, during periods of inactivity, will find shelter under leaf litter or rotting logs
Gopher tortoise inhabits sandhill oak forests, pine flatwoods, oak hammocks, and beach scrub forests from South Carolina to Florida and west to Louisiana.

Gopher tortoises will also scavenge and occasionally feed on dead animals.

Sea Turtles journey from the beginningHatchlings must leave the nest to safely get to the sea to find food, shelter, and warm water
So how do Sea Turtles do it?
They must rely on the reflection of the moon and stars on the ocean, the downward slope of the beach, and the lack of vegetation to get them to the sea.
And then they returnWhen the female is mature and is ready to lay eggs, she returns to the very beach at which she was hatched.She digs a hole, lays her eggs, and then returns to the ocean.
and the whole journey starts over again!
Turtle PartsTurtle PartsCarapace-top shell, an outgrowth of bone.
Flippers-pond turtle has flat feet, webbed toes for digging in mud, tearing food, courtship, sea turtle has broad flippers for swimming.
More Turtle PartsPlastron-bottom shell Scutes-scales over both shells, made of keratin like your fingernails
Neck-pond turtle can fold neck into its shell in S-shape, sea turtle can't
Even More Turtle PartsNostrils-near the top of head so turtle won't have to stick head far out of water to breatheBeak-no teeth, but jagged beak catches, holds, and slices food
Ears-no outside parts to slow it down underwater
