They're hard-shelled, air breathing reptiles that live in the tropical and subtropical seas of the world. And let's face it - they are adorable!

There are seven species of sea turtles in total. Let's count them:
1. Loggerhead
2. Green
3. Leatherback
4. Flatback
5. Hawksbill
6. Kemp's ridley and
7. Olive ridley.

Sea turtles come in many sizes, shapes and colors. The olive ridley weighs up to 45 kilograms/100 pounds while the leatherback can weigh up to 600 kilograms or 1300 pounds! Wow, that's one big turtle! How many of you would it take to weight up to one leatherback sea turtle?

Sea turtles live most of their lives in the open ocean and travel great distances. They're very graceful in the water and are awesome navigators. Can you believe adult females return to the exact same beach where they were born to lay their eggs in the sand? How do they find their way home? Scientists are still unlocking the clues to this mystery.

Sea turtles don't have teeth. Instead they have "beaks" they use to eat their favorite foods like sea jellies. When plastic bags and balloons get in the water, sea turtles often mistake them for jellies and eat the plastic by mistake. There are also other dangers facing our sea turtle pals including pollution, entanglement in fishing nets and destruction of nesting beaches.
