Contrary to popular belief, a turtle cannot come out of its shell. The turtle’s shell grows with them, so it’s impossible for them to grow too big for it!
"Turtle" is the umbrella term for all 200 species of the testudine group, which includes turtles, tortoises, and terrapins. All turtles have two distinct features: A shell to which their ribs and vertebrae are fused, and a pelvic girdle that sits inside their rib cage. This “compressed anatomical structure,” says Madrak, is what gives turtles their signature lumbering walk.
