Become a Community Scientist: Report Your Sightings

Observations you provide on porpoises, dolphins and whales are valuable and add to our knowledge of these species. If you have an interesting or unusual sighting of any cetacean, please send us your report by filling out the form below.



We are especially interested in reports of harbor porpoises in San Francisco Bay north of the Richmond-San Rafael Bridge or south of the San Francisco-Oakland Bay Bridge.

We would also like reports of bottlenose dolphins from Half Moon Bay north, and if you can take photos of their dorsal fins, we may be able to match a known individual to our catalog.

If you spot a whale anywhere in San Francisco Bay, we'd like to hear about it.

Remember, if you see a marine mammal that appears sick or injured, call The Marine Mammal Center's Stranding Hotline: (415) 289-7325.
