Two great white sharks were tagged off the coast of Massachusetts in the past week by the nonprofit group OCEARCH.

A female measuring 10 feet, 8 inches long was tagged Sunday and given the name Andromache, according to OCEARCH officials, after the Greek character “who symbolizes strength courage and maternity.”

Her movements can be tracked on the OCEARCH website. The group created for her a dedicated Twitter account (@AndromacheShark) where updates on her latest movements are posted.

“Just letting you all know that I’m off the coast of Nantucket a little south from where I was tagged,” Andromache tweeted on Tuesday.


The OCEARCH team tagged Andromache during a research trip called Expedition Massachusetts, which launched earlier this month. According to OCEARCH’s website, the data and insight gained from the trip will support 20 individual shark-related research projects that are being conducted by investigators from a number of different universities and organizations, including the Woods Hole Oceanographic Institution, the University of Florida, and Texas A&M University.

The second great white that OCEARCH tagged, dubbed Monomoy after the island he was spotted near, measured 6 feet, 7 inches long — smaller than most sharks that have been observed in the area.

“At 6′ 7″ long, he’s the smallest shark we’ve tagged in this area,” OCEARCH tweeted. “His presence means it’s not just big sharks here as is often perceived.”

Chris Fischer, the founder of OCEARCH and leader of the expedition, noted the small size of the second shark.

“It was stunning,” he said in a video posted on social media. “It was a male white shark less than 7 feet long. We have never seen a shark that small here in Massachusetts before.”

Fischer said that over the past week their the underwater cameras have been picking up images of other small sharks in the area, which “really shocked us, because when we first came up here a few years ago, it was all about big sharks.”


“There are small juvenile white sharks out here moving around these shoals, balancing out this system ... fish eaters.”
