Our Patients


Every year, on average, we help approximately 600 distressed marine mammals, rescuing and rehabilitating them at our hospital facilities in the Marin Headlands.

Our patients include include pinnipeds like California sea lions, northern elephant seals and harbor seals, as well as sea otters, whales, dolphins, porpoises, and even sea turtles.

We may have dozens of patients on site at any given time in various stages of treatment or rehabilitation.

The most common reasons these animals have been rescued and are under our care are:

H.C. was a California sea lion that was rescued when he was found to be entangled in a large plastic band. His story provides a good overview of the work carried out by The Marine Mammal Center, along with the treatment and care we give to our patients.
