Anatomical studies!
So, there was a line in TMNT’03 when Raph complains about his ribs that got me thinking, isn’t a turtles shell their ribs?
So, I did a little looking into the skeletal structure of turtles and how it might apply to the brothers, particularly the Rise brothers as they’re all different species. Here’s the little chart of common bone and scute patterns, and some speculation on how their reptilian features affects them!
I’ll post my individual skeletal studies after!
