    "summary": "Micro-CT scans linked internal vertebral mineralization across six shark species to speed, maneuvering, tail strikes and slow cruising.",
    "body_text": "Florida Atlantic University and NOAA researchers compared vertebrae from great white, shortfin mako, porbeagle, common thresher, sand tiger and basking sharks. Fast swimmers carried stiffer, mineral-rich architecture toward the tail, sand tigers favored flexibility, threshers reinforced structures for powerful tail strikes, and basking sharks had much less mineralization. The Journal of Anatomy study connects form with swimming style across specimens; it does not measure live performance directly or turn the anatomy into an engineering design by itself.",
