Shark tracks

You can follow Genie, Mary Lee and other tagged great white sharks at OCEARCH's website or visit their Facebook page.

Move over Mary Lee, Genie the shark is hanging out off the coast of Charleston - again.

After three months of silence, the nearly 15-foot, 2,292-pound great white shark pinged Sunday along the Continental Shelf, according to OCEARCH, the nonprofit organization that tagged the sharks to study their migrating habits.

Genie is far more coy than Mary Lee, not often pinging the satellite signal that is supposed to transmit whenever she breaks the surface. Mary Lee, a 16-foot, 3,456-pound great white, repeatedly has pinged since her 2012 tagging. She moved back in off Charleston from the deep ocean in November and has been cruising the region's coast for the past two months. She signaled Christmas Eve just off the mouth of the Savannah River.

Mary Lee became a social media sensation when she arrived outside the Isle of Palms breakers in November 2012, with the newly attached tracking device. A Web alert among surfers morphed into a pop trend of thousands tracking her every move, and made her a household name. Genie joined her in December 2012, pinging off Edisto Beach.

The great whites are among a few dozen sharks tagged by Ocearch to learn more about the little-known habits and haunts of the creatures.

Ocearch was engaged in low-key, somewhat publicity shy research when Mary Lee went viral. But oddly enough, her fame has gone a long way to accomplishing one of the chief research goals - promoting public appreciation for a grand animal of the ocean that had maybe the most sinister reputation.
