Old Thom, the solitary male orca known to frequent New England waters, was spotted just 10 miles off Nantucket on Wednesday by Capt. Shawn Deane of Sure Shot Charters, who shared this video with the Current.
Massachusetts shark biologist John Chisholm said Old Thom was easily recognizable in the clip due to his unique dorsal fin, which has a distinct notch.
While orcas typically travel in highly-structured family groups called pods, Old Thom is usually spotted alone in the waters of the North Atlantic, or sometimes cruising with a group of white-sided dolphins. Old Thom was most recently seen on Stellwagen Bank in April, and is a regular visitor to the Gulf of Maine, the Bay of Fundy, and the waters off Cape Cod.
Thanks to Capt. Shawn for sharing this incredible encounter with us!
