The Marine Mammal Center is a nonprofit veterinary research hospital and educational center. We are dedicated to the rescue of ill and injured marine mammals.
(742)

Since 1975, the Center has been headquartered in the Marin Headlands, Sausalito, Calif., within the Golden Gate National Park and has rescued and treated more than 20,000 marine mammals along 600 miles of the California coastline. In 2014, the Center opened Ke Kai Ola, a hospital for the rehabilitation of the critically endangered Hawaiian monk seal, in Kailua-Kona, Hawaii. Due to the volume of animals we rescue, we are the largest marine mammal hospital in the world. The Marine Mammal Center is a 501(c)3 nonprofit organization which relies on 80% of its funding from individuals like you.

Today we celebrate One Health Day 👏🌎

While much of our work to respond and rescue marine mammals is about giving individual patients the care they need for the best possible chance at life, it is also about populations as a whole, and the health of our ocean and humans alike. This approach is called One Health: the interdependency of human, animal, and environmental health and sustainability.

As our work expands and evolves, we prioritize making the biggest possible impact. Join our efforts by getting involved today 👉 link in the comments below 👇

This just in‼️Ke Kai Ola has some new swag 🦭🤭

We worked with local Kona artist, Keiko Saile, to design our new Hawaiian monk seal response stickers. Keiko is a watercolor painter, creating her own colors and palettes with natural pigments and binders—including Hawaiian honey! 🍯🐝 Much of Keiko’s work focuses on endangered native Hawaiian flora and fauna, including forest birds, snails, plants, and marine animals 🏝️🌿🐠🦜

If you catch us out in the community, you may just take one of these maikaʻi loa stickers home 🤙

This year, we have responded to more than 300 cases of domoic acid poisoning in marine mammals making it the largest outbreak since our founding in 1975.

This naturally occurring toxin can have severe impacts on marine mammals, causing tremors, seizures, and heart failure if left untreated. The scale of this outbreak underscores both the threats these animals face in our ocean and the challenges involved in addressing them.

California sea lions are a sentinel species, meaning their health can provide invaluable insight into the conditions of our shared ocean. As our ocean experiences rising temperatures and environmental pressures, marine mammals offer scientists a critical view into a changing ecosystem.

How you can help 👇

📏 Stay at least 150 feet away. Sick or injured wildlife can behave unpredictably
🦮 Keep pets leashed and away from wildlife
🙅‍♀️ Never touch or move an animal. Do not attempt to return a stranded animal to the water
📲 Call our response hotline at 415-289-SEAL (7325) to report sick or injured marine mammals
🫶 Please be patient. Response teams continue to manage an unusually high volume of calls and rescues
🤝 Donate to treat more marine mammal patients recovering from domoic acid poisoning

Our zodiac collection with Sarah's Scribbles is finally complete 🤩 with Ta**us ♉️

Europeans first named northern fur seals "sea bears," likely because of their thick fur coat 🧥 Making it no surprise why we chose them to represent this tactful, cozy-loving Earth sign 🌱 Plus, as our trained animal care team can tell you, these pinnipeds LOVE a snack 🐟 and absolutely have that stubborn bull energy 🐂😅

Shop the entire collection, including the Ta**us sticker, at our Gift Store (🔗 in comments) -- every purchase supports marine mammals in need 💕
