Donate to Seal Sitters

Founded in 2007, Seal Sitters Marine Mammal Stranding Network (SSMMSN) is an all-volunteer group dedicated to the protection of marine mammals and strives to inspire stewardship of our fragile marine ecosystem.

SSMMSN responds to reports of all species of marine mammals, dead or alive, along West Seattle’s coastline, including that of the industrialized Duwamish Waterway and Harbor Island. As a member of NOAA’s West Coast Marine Mammal Stranding Network, Seal Sitters provides health and mortalities data to government agencies and biologists who monitor marine mammal populations and emerging disease.

Seal Sitters has created a unique opportunity for protection, conservation, education and research in a highly challenging urban location.

We receive no funding from Federal, State or City governments to perform our service. Seal Sitters is thankful for generous donations from the public and businesses which enable us to continue our work. For more info, please visit
