According to the Turtle/Tortoise FAQ (Frequently Asked Questions): "In the USA - a turtle is found in or around water and a tortoise is found on dry land. In general, look at the back legs. If they are webbed, call it a turtle. If they are stumpy (like an elephants) call it a tortoise." "In the UK they apply terrapin to freshwater chelonians, tortoise to land chelonians, and turtle to oceanic dwellers. " "In Australia 'tortoise' is used for everything except sea 'turtles'. "
