Pacific Mammal Research

Pacific Mammal Research (PacMam) is a 501c3 non-profit organization dedicated to understanding more about marine mammal populations in the Salish Sea and passing on that knowledge through scientific publications and education.

This is a short but important read about the importance of biodiversity: www.seadocsociety.org/blog/nature-... "In this moment of fiscal strain, biodiversity funding is not discretionary spending. It is a down payment on our collective health, prosperity and future."

SeaDoc is a science-based marine conservation program. We understand that science informs policy, including priority setting and budgeting. Washington State faces difficult budget choices. With multi...

📸 Science in Action! Ever wonder what our researchers are doing on the shore? They’re conducting vital photo-ID surveys that allow us to identify and track individual porpoises over time without disturbing them. It goes to show how much we can learn by watching closely from the shoreline. 🌊🐬

When you get caught housing a meal... No shame in scarfing down a delicious snack in our book—definitely no judgement from this hungry harbor seal. 🦭🐟 As an opportunistic feeders they can be spotted munching on a mangled marine animal at any hour of the day!

🌊 New Year, New Impact! 🌊 Want to make a difference in 2026? Join our mission to protect the incredible marine life of the Salish Sea! We're looking for volunteers to help with harbor porpoise and harbor seal research. No biology background needed—we provide all the training!

As winter blankets Washington's peaks in snow, our marine ecosystem thrives below... The mountain watershed nourishes Puget Sound, creating perfect habitats for harbor seals, orcas and other marine mammals. Nature's cycles connect mountains to sea. How are you savoring this winter season? ❄️🗻🌊🐋

Meet Paintbrush - we have seen this harbor porpoise for the past 6 years, since 2020! This is the power of photo-ID, getting to know the individuals in the population and more about their daily lives. Do you see the marks and pigmentation patterns that are the same?

Act cool they’re watching 😳😎 These two sea lions are clearly not in the mood to share their sunbathing spot with this newbie. We can’t blame them, but what a graceful exit this little guy pulled off. 🦭

Did you know Harbor seals are opportunistic predators? This means when octopus are locally abundant they become a food source for hungry seals. While the realities of nature aren’t always pretty, the interconnected relationships species maintain are essential for healthy self sustaining ecosystems.

A series of predictable events... Unfortunately for this gull, a hard earned hefty catch like this one isn’t going to be given up so easily. New strategy? The #LongGame, with the hopes that over time this seal might warm up to idea or drop a few scrapes in the process. 🥊🦭

Can you spot the difference between porpoises and dolphins?🐬👀 A couple differences: Porpoises have round, blunt mouths unlike dolphins' elongated snouts. Dolphins have curved dorsal fins while porpoises have smaller, triangular ones. 📷: Harbor porpoise: Cindy Elliser, Pacific Mammal Research

We recently published a study showing long-term site fidelity for harbor porpoises in the Salish Sea…but what the does that mean? 🔬🐬 Long-term site fidelity roughly means an animal is returning to and remaining in the same geographic location year over year. 🔎https://www.mdpi.com/2673-1924/6/1/9

Excited to have our colleague Bill Keener from the Marine Mammal Center in CA out to the field site today! We have collaborated with him and other colleagues on many papers on foraging and mating behaviors of harbor porpoises. Together we are learning more about this amazing species! #collaborations
