Mary Lee is now due east of Cape May, less than 20 miles offshore, according to the most recent GPS ping from the shark.

But Mary Lee isn’t alone. Another great white shark, a male named Cisco, pinged near the mouth of Delaware Bay Saturday morning.

Mary Lee, the 16-foot, 3,500-pound great white shark with her own Twitter account, has been known to travel up and down the East Coast each spring.

The shark was tagged off Cape Cod, Massachusetts, in September 2012 by nonprofit group OCEARCH. Each time Mary Lee’s dorsal fin surfaces, a ping is emitted that is tracked on an app, Twitter and the nonprofit’s website.

A few days ago, Mary Lee popped up just east of Fenwick Island, Delaware.

Cisco, who also has his own Twitter, is logged as an immature shark that is 8 feet long and 362 pounds. He was tagged in October 2016 and last pinged off Dewey Beach in Delaware.

Could Mary Lee and Cisco be out on a romantic shark date Saturday night? Fingers and fins crossed.
