BOSTON >> Crews have disentangled a nearly 60-foot-long fin whale that was spotted swimming with fishing rope and buoys lodged in its mouth east of Boston.

WCVB-TV reports that crews helped the whale Wednesday after a tuna spotter pilot saw it on Stellwagen Bank.

The pilot alerted the Center for Coastal Studies and stayed with the animal until the Marine Animal Entanglement Response team arrived.

Responders threw a grappling hook overboard and a buoy to help dislodge the entanglement. When the whale dove, it dragged the buoy with it, which allowed the hook with 60 feet of line to cut through the large loop of fishing ropes. The team then repeated the process.

Recreational boaters had first spotted the entangled whale on Saturday.
