Figure 2. Thin sections of vertebrae from three sawfish.

Digital images of thin sections of smalltooth sawfish vertebrae centra from carcasses opportunistically sampled in south Florida from 2003 through 2012. Vertebrae were from A) a 1.50 m TL male (fish 8 in Table 1), B) a 2.22 m TL female (fish 7), and C) a 4.35 m TL female (fish 13). Black circles indicate opaque zones, with the first opaque zone in each section being the natal mark following birth.
