A great white shark was detected Thursday off the coast of Cape Cod.
The Atlantic White Shark Conservancy said in a tweet Thursday morning that a great white that has been dubbed Scratchy was detected on the shark cove receiver off Monomoy Island in Chatham.
The shark - a 13-foot male - was originally tagged last August.
The latest news from around the state
According to the Massachusetts Division of Marine Fisheries website, Scratchy got his name because of the large number of scratches from seals along its side.
The Atlantic White Shark Conservancy began its 2016 research season Thursday, but one report of a seal that appeared to have been bitten by a great white shark was received on Tuesday.
The first great white sharks generally arrive off the cape in mid- to late-June, once the water temperatures get close to 60.
