Female rock iguanas lay about 20 eggs and green iguanas lay about 65 eggs.
When the babies hatch, they must make their way to the sea by themselves.
But racer snakes await. They eat baby iguanas so they take advantage of when the baby iguanas make their way to the sea.
The babies must make sure that the snakes don't find and eat them in order to survive and get to the sea.
Green iguanas have sharp teeth and powerful tails that come in handy when dealing with predators. They also have sharp eyesight. Rock iguanas are able to have quick bursts of speed that come in handy while running a short distance.
Not all of the hatch lings make it to the sea. The ones who do have very close escapes from the racer snakes. Escaping from the racer snakes is the most dangerous battle that the iguanas will have to fight.
