"I am a turtle."
Translation:Sono una tartaruga.
The Oxford English Dictionary seems to be wrong about this. My edition of the OED says that turtles are marine tortoises. In this case, I prefer Funk and Wagnall, which says all members of the order Chelonia are turtles, whether they live in the sea, freshwater, or on land. In British English, turtles have flippers and live in the sea. Tortoises live on land and have feet like elephants.
