Pure-white, Arctic-dwelling beluga whales and their black and white cousins the orcas are rarely seen in the Atlantic outside of icy polar waters. While orcas migrate around the globe and inhabit both Arctic and Antarctic waters, belugas are usually at home only in the frozen north. Massachusetts residents, then, are unlikely to ever see these whales, but this month prospective whale watchers might get lucky. Just a few days ago, both whales were spotted in Massachusetts—quite a distance south from the whales’ usual frigid habitat.
On June 15th, a lone beluga was seen in the mouth of the Taunton River in Fall River, Massachusetts. The sighting was rare for two reasons: first for its distance from the arctic and second because belugas usually travel in pods and are rarely seen alone. This beluga, however, which appeared to be a healthy adult male, cruised around solo in the river for several days, delighting the citizens of Fall River but worrying advocates concerned for the whale’s safety. Meanwhile, on June 25th, the U.S. Coast Guard came across a pod of orcas about 150 miles off the coast of Nantucket. The picture below shows the orcas surfacing beside the CGC Campbell.
Scientists have been both pleased and puzzled by the unexpected appearances. While the sighting of such rare visitors to New England is certainly exciting, there may be an unfortunate reason for these whales’ presence here. Researchers from Mystic Aquarium suspect that both the beluga’s and the orcas’ movements may be an indication of melting Arctic ice and of the impact this environmental change has on the Arctic’s inhabitants—the whales may have been driven south in search of more abundant food. These aren’t the first polar visitors to New England this year, either—a bowhead whale was spotted in April off the coast of Cape Cod.
The verdict is still out, however, on what the connection is between melting ice and wandering whales. In the meantime, we can enjoy the rare sight of these beautiful creatures.
