Summer shark season has officially arrived, as three great white sharks were spotted off different areas of Cape Cod on Monday morning.
According to the Atlantic White Shark Conservancy's Sharktivity app, two great whites were spotted Monday afternoon in Cape Cod Bay.
The Cape Cod Chronicle said the Chatham harbormaster also reported seeing a 13-foot great white shark eating a seal near Monomoy Island on Monday morning.
No further information on the sightings was immediately available.
Just last week, police in Manchester-by-the-Sea on the North Shore of Massachusetts reported that a large shark was spotted near House Island. Swimmers were told to be cautious but not ordered out of the water.
The sharks typically return to the Massachusetts area sometime in June. Researchers with the Atlantic White Shark Conservancy were scheduled to be out on the water on Monday.
Two people were attacked by sharks on Cape Cod last year, including Massachusetts' first fatal attack since 1936. The first attack occurred on Aug. 15 at Longnook Beach in Truro. The victim, a New York man, survived but was badly injured. The second attack on Sept. 15 at Newcomb Hollow Beach in Wellfleet claimed the life of 26-year-old Arthur Medici of Revere.

Ever since, towns on the Cape have been wrestling with a variety of possible solutions for the shark crisis, including building ocean barriers and reducing the seal population.
