Fin whales reach Maine waters as visitors passing through deep water, not residents of any single bay, and the state’s 45 occurrence records trace scattered summer encounters rather than a resident presence.
Following baitfish into the Gulf of Maine
Fin whales lunge-feed on schooling fish and krill, turning sideways through a ball of prey with mouths open. Maine’s stretch of the Gulf of Maine, including the deep basins and ledges that extend south toward Jeffreys Ledge, concentrates the herring, sand lance, and krill this whale needs, drawing animals in from farther offshore through the warmer months.
A summer visitor, not a Maine constant
Maine’s records climb sharply in June and July and fall off fast by fall, matching the months when Gulf of Maine baitfish schools run thickest. Once the water cools and prey scatters, fin whale sightings in Maine waters largely disappear until the following summer.
Status in Maine
NatureServe hasn’t assigned Maine a specific conservation rank for this species, since a fin whale spends most of its life in open ocean beyond what any one state can track, and its status here reads as unranked. It’s classified as native to Maine’s waters.
