GREEN TURTLE 
In shallows not far from the shore, green turtles graze along the bottom 
of the ocean on seaweeds, shrimps, lobsters and small shellfishes. Like 
other sea turtles they must from time to time come to the surface for air. 
The shell of these marine reptiles is olive or brown with yellow blotches; 
the breastplate or plastron is yellow. The term “green” arises from the 
greenish fat inside the shell. The surface of the shell is frequently covered 
in part with clusters of barnacles and short fronds of seaweed.
