Question

　　Strange, but the green sea turtle(小海龟)is not that green．It’s certainly not as green as a tree．In fact, its shell(壳)is nearly black or brown．The largest hard-shelled sea turtle is between 200 and 300 pounds heavy and a shell is between 36 and 43 inches(英尺)long．But its head is smaller than other turtles．

　　Little baby green sea turtles are only two inches long．As the turtle grows up, its shell keeps mostly black while the body turns orange or brown．Young turtles like living in the sea, especially in areas with lots of sea grasses．

　　Green sea turtle, like all sea turtles, are very different from land or river turtles．All sea turtles can swim through the water faster．Instead of feet for walking, sea turtles have flippers(鳍状肢)which are better for swimming．The flippers aren’t much good on land, however, and walking is hard for a sea turtle because they are usually big and heavy．

　　Another interesting thing about a sea turtle’s flippers is that they cannot be pulled into their shells．Land turtles can pull their feet into their shells for protection, but a sea turtle can’t．
