March 6, 2026 — Blue whales, the largest animals on Earth, have been spotted not far off the coast of Massachusetts in what the New England Aquarium is calling an “unusual occurrence.”
Researchers with the aquarium spotted two blue whales just 15 miles south of Martha’s Vineyard on Saturday during an aerial survey. The day before, they saw a blue whale at Lydonia Canyon, 170 miles away to the southeast of Nantucket.
The aquarium team has never encountered a blue whale in the southern New England survey area before. The most recent sighting of the endangered species in the area had been off the coast of Maine in 2023. A blue whale was also spotted off Cape Cod, 13 miles east of Truro, by the Center for Coastal Studies in 2020.
