Interesting facts about sea turtles

  1. Sea turtles lay their eggs in a nest they dig in the sand with their rear flippers. The group of eggs is called a clutch.
  2. Sea turtles usually lay 100-125 eggs per nest and will nest multiple times over several months. 
  3. It depends on the temperature of the sand and the sex of the sea turtle. If it is colder it will produce males, and females if it is warmer.
  4. Leatherback sea turtles have existed in their current form since the age of the dinosaurs!
  5. Unlike other turtles, sea turtles do not retract into their shells.
  6. As reptiles, sea turtles breathe air, but they have the ability to remain submerged for hours at a time. They even sleep underwater. 
  7. There are 7 species of sea turtles.
  8. Turtles don’t have teeth.
  9. Marine turtle species vary greatly in size. The smallest measure around 28 inches long, and weigh up to 90lb, whilst the largest can reach up to 6ft long and weigh 1,100lb. 

These are just ideas, let the children come up with their own answers.
