When they are young the turtles are omnivores. They eat crabs, jellyfish and worms, but as they mature they become herbivors meaning they eat sea grass and algae.
When the turtles are born they are only 5cm or 2in.
When they grow up they can be up to 1.5 meters weighing up to 300kg! This makes them the biggest hard shell turtle.
