Mariners are being urged to proceed with caution through the waters of Martha’s Vineyard and Nantucket following the probable sighting Sunday of three right whales north of Oak Bluffs.
The whales were spotted two and three miles offshore, said Tim Cole, a fisheries biologist with the National Fisheries Science Center in Woods Hole.
Less than 450 Atlantic right whales are known to be in existence, making them one of the most endangered marine mammals in this area.
