A rare fin whale turned up grounded and dead on the shallow tidal flats near Samish Island on Monday, triggering a fast response from marine mammal investigators. The carcass washed in close to shore, and responders shut down the immediate area while they worked. Residents and beachgoers were told to steer clear while experts examined the animal.
NOAA officials confirmed the discovery and said it is the first recorded fin whale death in Washington this year, according to FOX 13 Seattle. The whale was reported near the Gravely Beach area of Samish Island, and responders from the West Coast Marine Mammal Stranding Network were dispatched after a public call came in. Investigators plan to perform a necropsy to determine whether the animal was sick, entangled, or struck by a vessel.
Sighting logs and reports from professional whale-watch operators show fin whales have been popping up in the Salish Sea since last September, giving researchers some recent context for these unusual visitors, according to Western Washington University. Captains and naturalists photographed fin whales near Salmon Bank and McArthur Bank last fall, and a handful of sightings carried into 2026. Those community reports and photos help biologists check whether stranded animals match individuals that have been seen alive offshore.
Fin Whales Rarely Roam the Salish Sea
Fin whales are the second-largest whale species on the planet and are uncommon in Puget Sound, which makes any stranding in local waters stand out, according to the Encyclopedia of Puget Sound. They are sometimes nicknamed the “greyhound of the sea” for their speed, a detail noted by conservation groups such as Whale and Dolphin Conservation. In earlier Salish Sea fin whale strandings, researchers often found signs consistent with vessel strikes, so investigators will be looking closely for trauma as one possible cause…
