The life of a sea turtle

One of my lifelong dreams is to be a sea turtle. You use your beak to crack the thick shell of the egg open. You see your brothers and sisters hatching around you. You get out of the cracked shell, and crawl to the water. You close your eyes as the water slowly swallows you. You open your eyes, see the beautiful coral, and blue(or green) water of the sea. You swim lower, as the sea draws you deeper. You aren't afraid of anything, not even the dark depths of the sea. Suddenly, you feel something behind you... You turn your eyes backward... And, to your huge surprise, it is a shark. You quickly swim under the nearest rock. The shark swims away... You swim upward, and see a forest of sea grass. You, being quite hungry, feed on it. Now you swim forward, on to the mystries of the sea... What does its depth hold for you?
