The surprising anatomy of the turtle 1 Shell Its her built-in home, always carried on her back. 2 Spine Its fused with the shell, so turtles cant simply leave their shell. 3 Ribs Theyre attached to the shell too, which makes their breathing very different from ours. 4 Plastron The underside part, acting as a protective belly shield. A true little armored creature, moving slowly but steadily! #turtle #wildlife #fblifestyle
