Detailed explanation-1: -turtle, (order Testudines), any reptile with a body encased in a bony shell, including tortoises. Although numerous animals, from invertebrates to mammals, have evolved shells, none has an architecture like that of turtles.

Detailed explanation-2: -The eastern box turtle is one of six extant subspecies of the common box turtle. It has a high-domed, rounded, hard upper shell, called a carapace.

Detailed explanation-3: -Tortoises (/ˈtɔːr.təs.ɪz/) are reptiles of the family Testudinidae of the order Testudines (Latin: tortoise). Like other turtles, tortoises have a shell to protect from predation and other threats.

Detailed explanation-4: -Tortoises are a group of turtles that can be distinguished in part by their round, dome-like shells. This shape provides protection from the teeth and claws of predators and helps a tortoise to right itself if it happens to roll (or be flipped) onto its back.

Detailed explanation-5: -Tortoises have more rounded and domed shells where turtles have thinner, more water-dynamic shells. Turtle shells are more streamlined to aid in swimming. One major key difference is that tortoises spend most of their time on land and turtles are adapted for life spent in water.
