Tortoises vs Turtles

Tanto las tortugas de tierra (tortoise) como las marinas (turtle) son dos reptiles de la orden de Testudines, pero pertenecen a diferentes familias de clasificación . La principal diferencia entre las dos es que unas habitan en la tierra, mientras que las otras lo hacen en el agua o muy cerca de ella.
Los cuerpos de ambas tortugas están protegidos por una concha, a la parte superior se le llama caparazón, la parte inferior es el plastrón. El caparazón y el plastrón están unidos por un puente, lo que significa que aunque la cabeza y las extremidades pueden ser retirados de la concha, el cuerpo no puede ser en ningún caso totalmente separado de ella. Estos reptiles son generalmente solitarios y tímidos. La tortuga de tierra vive entre 80 y 150 años, aunque algunas han sobrepasado los 300, son mayormente hervíboras. Las de agua son omnívoras, pesan menos y también viven menos, entre 20 y 40 años.




Tortoises and turtles are both reptiles from the order of Testudines, but in different classification families. The major difference between the two is that tortoises dwell on land, while turtles live in the water some or nearly all of the time.
The bodies of tortoises and turtles are both shielded by a shell, the upper part of which is called carapace, with the lower portion called a plastron. The carapace and the plastron are attached by a bridge, which means that though the head and limbs of a turtle or tortoise may be withdrawn from the shell, the whole body can never be totally detached from it. These reptiles are generally reclusive and shy in nature.
