Now, new research provides intricate details showing that vertebrae anatomy might support the mechanics of extreme body bending in thresher sharks, enabling these expert hunters to weaponize their tails. Using micro-CT scanning similar to CAT scans in humans and two-dimensional shape analysis, results suggest vertebral anatomy and mineralized microstructure meet the demands required for fast swimming and tail-whipping behavior seen in these species.
