An 80-foot blue whale gave tourists a rare treat Sunday when it made an appearance off the coast of Maine during a whale-watching tour.
The critically endangered mammal was spotted about 15 miles from Boothbay Harbor by passengers aboard the Pink Lady II, a whale watching boat.
The 80-foot whale remained about 10 feet underwater, logging, or sleeping, while onlookers watched in awe.
“We don’t expect to see blue whales in the Gulf of Maine,’’ said Dominique Leclerc, a staff naturalist on the boat. “People were clapping and cheering, just having a grand old time.’’
