Marine wildlife enthusiasts are giddy over the recent sighting of a killer whale in the waters off Chatham.
The Atlantic White Shark Conservancy has shared several videos of Sunday's super rare encounter online.
The Dolphin Fleet Whale Watch later identified the bull orca as Old Thom, who has a distinctive dorsal fin.
He's made several visits to the region in recent years and has been known to travel with a pod of white-sided dolphins.
