Did you know that a turtle（乌龟）can lay 12 eggs in oneminute? A large sea turtle lays around 150 eggs at a time. She lays all theseeggs in just a few minutes.

Large sea turtles live in the warm seas ofthe world. Except for when they lay their eggs, they spend their whole lives inthe water. When it is time to lay their eggs, the females(雌性) swim to land.

They usually return to the place where theythemselves were born. How they find their way back there is unknown.

When they reach shore, the big, heavyturtles crawl slowly up to the high water mark. Using their flippers, they pullthemselves along the sand. They must struggle like mountain climbers.

When they finally reach dry sand, they restbefore beginning the difficult task of laying eggs.

The turtles lay the eggs in deep holes andcover them with warm sand. The sand protects the eggs from harm. Then thefemales leave them. After a few weeks, if you happened to be walking along thebeach, you might see the sand begin to shake. You may see tiny black ballscoming out of the sand. The tiny heads of baby turtles!
