Etymology
Noun
tortoise (plural tortoises)
Any of various land-dwelling reptiles, of the family Testudinidae (chiefly, North America) or the order Testudines (chiefly, UK), whose body is enclosed in a shell (carapace plus plastron). The animal can withdraw its head and four legs partially into the shell, providing some protection from predators.
Synonym: shellpad
Usage notes
Differences exist in usage of the common terms turtle, tortoise, and terrapin, depending on the variety of English being used. In American usage, turtle is often a general term; tortoise is used only in reference to terrestrial turtles or, more narrowly, only those members of Testudinidae, the family of modern land tortoises; and terrapin may refer to turtles that are small and live in fresh and brackish water.
British usage, by contrast, tends not to use turtle as a generic term for all members of the order but instead as a synonym for sea turtle specifically, and also applies the term tortoises broadly to all land-dwelling members of the order Testudines, regardless of whether they are actually members of the family Testudinidae.
Land tortoises are not native to Australia, yet traditionally freshwater turtles have been called tortoises in Australia.
