Three great white sharks were spotted around Cape Cod Monday, officials said.
A 13-foot great white was spotted “feeding on a seal” around 11 a.m. off the southern tip of Monomoy Island, said Chatham Harbormaster Jim Horne.
Horne said just before 1 p.m. that there had been no further information about the shark leaving the area, but that it was at least five miles from the beaches.
“They’re always down there. Wherever the seals are that’s where the sharks are,” he said.
A seal carcass with “bite wounds” was found off the island Saturday, the Atlantic White Shark Conservancy said on Facebook that afternoon.
“This time of year, white sharks are moving back into the area,” the post warned.
Two sightings were reported to the Conservancy Monday afternoon just off Wellfleet Harbor, according to the Sharktivity app, including previously tagged Ashley Grace, a 12-foot female.
Another sighting of an untagged shark was reported at 12:42 p.m. nearby, but it was unclear how close to shore the two were.
Researchers had previously announced they would be focusing efforts on shark research within the bay, citing the uptick in sightings in recent years.
“We don’t believe it’s a separate population,” Greg Skomal, senior fisheries scientist with the state Division of Marine Fisheries, told the Globe last week. “We just want to look at the connectivity between the bay and the outer Cape.”
