The Mainer who snapped the photo says it appeared the endangered fish had been hit by a propellor.

A Maine man caught a rare sight on camera over the weekend.

Ken Kantro tells WMTW he was walking on Pine Point Beach in Scarborough when he came upon a large Atlantic Sturgeon that had washed up with the tide.

He said the roughly six-foot-long fish appeared to have been hit by a propellor.

"It was awe-inspiring, but sad to see this “living fossil,” Kantro said.

He told WMTW he’s been living in Maine for 60 years.

According to the National Oceanic and Atmospheric Administration’s Fisheries sector, Atlantic Sturgeon can weigh up to 800 pounds and 14 feet in length, over a lifespan that can reach up to 60 years.
