HATTERAS, N.C.—A 16-foot great white shark named Mary Lee is among those who like calling North Carolina home.

The Ocearch Shark Tracker has kept track of the 3,500-pound Mary Lee since she was tagged in September off the coast of Cape Cod, Mass. On Wednesday, she was off the Outer Banks.

So far, she has traveled up and down the East Coast, including Florida, where she came within 200 yards of Jacksonville Beach a couple of weeks ago. In December, she entered the mouth of the Cape Fear River in southeastern North Carolina before traveling south.

Businessman and adventure show producer Chris Fisher says tens of thousands of people are following Mary Lee's travels online.
