What Whales You Actually See Off Boston

Three species do the work on Stellwagen Bank, and one that people ask about is simply not here.

Humpbacks — the reason to go

The demonstrative one. Humpbacks lunge-feed through schools of sand lance, sometimes blowing bubble nets to concentrate them, and they breach. They are also individually identifiable by the markings on the underside of the tail, which is why the naturalists can often name the animal you are looking at.

Fin whales — the big one

The second-largest animal on earth, and far less theatrical. A fin whale surfaces, blows, and goes about its business. The impression is of size rather than action.

Minke whales — the common one

Smaller, quick, easy to miss and frequently the first thing you see.

Also possible

Pilot whales, Atlantic white-sided dolphins, seals, and basking sharks. In April and May, critically endangered North Atlantic right whales pass through under strict vessel-distance rules.

Orcas: no

Orcas exist in the North Atlantic but are not part of this ecosystem in any practical sense, and no Boston operator can offer them. If a page implies otherwise it is chasing a search term. The animals here are the ones above, and a good humpback encounter beats a distant anything.
