McBride named the female shark Genie after renowned shark researcher Eugenie Clark.

After nearly 15 minutes, everybody scrambled off as the lift was lowered back into the water.

McBride grabbed Genie's tail and slowly guided her back into the ocean. They were done in 16 minutes flat. Genie drifted down into the dark water. The crew clinked beer cans and soda cups.

"That one shark alone was worth the trip," McBride said, noting she might lead researchers to breeding and birthing sites. "Any time we tag a great white shark it adds tremendous information to what we already know, which is very little."

Genie has pinged several times in the waters off Nantucket. So far, she's the crew's only catch.
