Great white shark George and Mako shark Oscar pinged off the coast of the Outer Banks this week, according to the Ocearch global shark-tracker program.

George, a 9-foot-10 inch, 702-pound shark tagged in Massachusetts in 2016, pinged about 25 miles off the coast of Ocracoke around 9:30 a.m. Monday morning. He’s believed to be the son of Mary Lee, the great white made Internet-famous by Ocearch and Twitter in the last few years.

On Tuesday, a tagged Mako shark named Oscar, weighing in at 320 pounds and 7 feet 8 inches long, pinged about 50 miles off the coast of Nags Head at 5:55 a.m. Oscar was tagged in Cape Cod in 2015.

Ocearch is a Massachusetts-based organization dedicated to tracking and studying sharks in conjunction with conservation outreach and education.
