Marine Mammal Stranding Network

The National Oceanic and Atmospheric Administration (NOAA) West Coast Marine Mammal Stranding Network coordinates information surrounding marine mammal strandings. The HSU Vertebrate Museum is responsible for all dead strandings from Pelican State Beach (near the Oregon border) to Sinkyone Wilderness State Park (north of Highway 1, Mendocino County). We also assist in live strandings and the necropsy of specimens that die during rehabilitation efforts. Our participation includes gathering data on specimens (species, sex, size, condition, etc.), collecting tissue samples for toxicological and genetic studies, examining stomach contents and studying parasites.

If you find a stranded or deceased marine mammal in our region, please contact the Marine Mammal Stranding Hotline at 707-826-3650 and we will coordinate an effort to assist the stranded animal or to collect the specimen. The Marine Mammal Protection Act makes it illegal to harass living marine mammals or to collect or possess any parts of deceased marine mammals without proper permits and authorization.

To report a stranded marine mammal please provide the following information:

  1. A description of the animal. Estimate the size, color, and other distinguishing features. Is the animal a seal, sea lion, dolphin, or whale? Is the animal alive or injured? If not, what is the condition of the body (e.g., decomposed, missing parts)?
  2. An accurate description of the stranding location, including the name of the beach and the distance from the nearest parking lot, road or trail.
  3. Record the date and time you last saw the animal. Also, please leave your name and phone number in case you need to be contacted to provide further information.
  4. Please note any other information that may be valuable in finding the animal, or that may have contributed to the injury or death of the animal.
