We launched Sharktober and Sharktoberfest celebrations in 2008 to celebrate the return of the white sharks to our Sanctuary offshore, and to educate and motivate the public to protect sharks.

The basic configuration of a vertebra varies; the large part is the body, and the central part is the centrum. The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles, two laminae, and seven processes. The laminae give attachment to the ligamenta flava (ligaments of the spine).
