Teaching the Parts of a Sea Turtle
When introducing the parts of a sea turtle to your students, it’s important to use language and vocabulary terms they are familiar with. Here are our recommended definitions for each part of the sea turtle. Each description provides a visual description as well as a purpose and how each part helps the sea turtle live in the ocean.
shell: the hard, smooth covering on a sea turtle’s back and belly. It is attached to the turtle’s bones and protects its body like a suit of armor, so a sea turtle can never crawl out of its shell!
head: the front part of a sea turtle’s body that sticks out from the shell. Unlike many land turtles, sea turtles can’t pull their heads inside their shells to hide!
eyes: two dark eyes on the sides of the head. They help sea turtles see clearly underwater, and sometimes it looks like sea turtles are crying, but those “tears” are just extra salt from the ocean water leaving their bodies!
mouth: the part of the head a sea turtle uses to eat. Sea turtles don’t have teeth! Instead, they have a hard, sharp beak for biting and munching on seagrass, jellyfish, and other ocean food!
front flippers: the two long, flat flippers near the head. Sea turtles flap them up and down like wings to swim through the water!
back flippers: the two smaller flippers near the tail. They help the sea turtle steer while it swims, and mother sea turtles use them to dig nests in the sand for their eggs!
tail: the short, pointy part at the very back of the shell. Boy sea turtles have long tails, and girl sea turtles have short tails, which is one way scientists can tell them apart!

Teaching the Life Cycle of a Sea Turtle
Since raising sea turtles in the classroom isn’t possible, the best way for students to learn about their life cycle is through photos, videos, and live nest cams from sea turtle rescue centers! Encourage students to notice how a tiny hatchling grows into a giant ocean traveler. Help students learn that some stages have more than one name they can use interchangeably (i.e. hatchling and baby turtle, or juvenile and young turtle).
egg: a round, white, leathery egg about the size of a ping-pong ball. A mother sea turtle crawls onto the beach, digs a deep hole in the sand with her back flippers, and lays about 100 eggs before covering them up and heading back to the ocean. The eggs stay warm in the sand for about two months!
hatchling: a tiny baby sea turtle that has just hatched from its egg. Hatchlings dig their way out of the sand together, usually at night, and race toward the bright, shiny water to start their life in the ocean!
juvenile: a young sea turtle that is still growing. Juveniles spend years drifting and swimming in the ocean, often hiding in floating seaweed where they can find food and stay safe from predators!
adult sea turtle: a fully grown sea turtle with a big, strong shell and powerful flippers. It can take 20 years or more to become an adult! Then mother sea turtles swim back to the very same beach where they hatched to lay eggs of their own!

Amazing Sea Turtle Facts
Seven Kinds: There are seven species of sea turtles: green, loggerhead, leatherback, hawksbill, Kemp’s ridley, olive ridley, and flatback.
Giant Swimmers: Leatherbacks are the biggest sea turtles in the world and can weigh up to 2,000 pounds, about as much as a small car!
Ancient Ocean Travelers: Sea turtles have been swimming in the ocean for over 100 million years, since the time of the dinosaurs.
Warm Sand, Girl Turtles: The temperature of the sand decides whether a baby turtle will be a boy or a girl. Warmer sand makes more girls, and cooler sand makes more boys!
Long Breath Holders: When they are resting or sleeping, some sea turtles can stay underwater for several hours without coming up for air.
Deep Divers: Leatherbacks can dive more than 4,000 feet deep in search of jellyfish to eat.
Not So Green: Green sea turtles aren’t named for their shells. They get their name from the greenish color of the fat under their shells, which comes from eating seagrass and algae!
Long Lives: Sea turtles can live for 50 years or more, and some may even live to be 100.

This fill-in-the-blank worksheet reinforces adaptation vocabulary using context clues. A teacher copy with answer key is included.
How Sea Turtles Survive in the Ocean
When introducing sea turtle adaptations to your students, it’s important to use language and vocabulary terms they are familiar with. Here are our recommended definitions for each term, along with how each one helps the sea turtle survive in the ocean.
flippers: the long, flat, paddle-shaped limbs a sea turtle uses instead of feet. The front flippers flap like wings to push the turtle through the water, and the back flippers help it steer, making sea turtles strong, graceful swimmers!
streamlined shell: a smooth, flat, rounded shell that lets water slide easily over the turtle’s body. Just like a swimmer wearing a cap and goggles, this shape helps sea turtles glide quickly through the ocean!
salt glands: special body parts near a sea turtle’s eyes that get rid of extra salt from the ocean water it swallows. When the salt leaves its body, it can look like the sea turtle is crying!
diving ability: being able to swim deep underwater and stay there for a long time. Sea turtles can slow down their heartbeat to save air, which helps them hold their breath while they search for food or rest!
camouflage: colors or patterns that help an animal blend in with its surroundings. A sea turtle’s dark shell blends in with the deep water when seen from above, and its lighter belly blends in with the bright sunny surface when seen from below, helping it hide from predators!

How Sea Turtles Navigate the Ocean
When introducing sea turtle migration to your students, it’s important to use language and vocabulary terms they are familiar with. Here are our recommended definitions for each term, along with how each one helps sea turtles find their way across the ocean.
migration: a long trip that animals take from one place to another, usually at the same time each year. Sea turtles migrate between the places where they eat and the beaches where they lay their eggs, and some swim thousands of miles to get there!
nesting beach: the sandy beach where a mother sea turtle digs a nest and lays her eggs. Amazingly, most mother sea turtles return to the very same beach where they hatched, even if it’s been 20 years or more!
ocean current: a giant stream of moving water that flows through the ocean like a river. Baby sea turtles ride ocean currents far out to sea, and adult turtles use them like a water highway to save energy on long trips!
navigation: finding your way from one place to another. Scientists believe sea turtles can sense Earth’s magnetic field, which works like a built-in compass to help them know which way to swim!

Protecting Sea Turtles for the Future
When introducing sea turtle conservation to your students, it’s important to use language and vocabulary terms they are familiar with. Here are our recommended definitions for each term, along with how each one connects to the ways people are helping sea turtles today.
endangered species: a kind of plant or animal that is at risk of disappearing forever because there are so few of them left. Most kinds of sea turtles are endangered or threatened, which is why so many people are working hard to protect them!
plastic pollution: plastic trash like bags, bottles, and straws that ends up in the ocean. Floating plastic bags can look a lot like jellyfish, so sea turtles sometimes eat them by mistake. Recycling and using less plastic helps keep the ocean clean!
habitat loss: when an animal’s home is damaged or taken away. When beaches are covered with buildings or ocean plants and coral reefs are harmed, sea turtles have fewer safe places to nest, eat, and live!
conservation: protecting and taking care of nature and the animals that live in it. Thanks to conservation, some sea turtle populations are growing again, and kids can help too by picking up trash and spreading the word!
nesting beach protection: keeping beaches safe for mother sea turtles and their eggs. Volunteers mark nests so people don’t step on them, and beach towns turn off bright lights at night so hatchlings can find their way to the ocean!
