Sea lions

Once a rescued marine mammal has been brought to our center, we provide the animal with medical attention and care during its recuperation period. We operate much like a human or domestic animal hospital in treating our patients. However, marine mammals have unique adaptations to life at sea that present challenges which require special medical care.For example, pinnipeds have a thick blubber layer that rejects many suture materials, and surgery is complicated due to their dive reflex, which causes their heart rate to slow, their breathing to stop, and their blood to pool centrally during anesthesia.

Husbandry is the core of our rehabilitation efforts – this includes nutrition, handling techniques, hygiene and sanitation, housing, disease prevention, and stress reduction. Volunteers help us with many aspects of our rehabilitation and release efforts, including much of the day-to-day care of the animals.

We constantly refine our protocols in order to provide the highest level of care possible for the animals while they receive medical attention and recuperate.

Maintaining the animals' wildness and reducing the stress they experience is an integral part of our work. The animals are not used to interacting with humans, and we want to be able to eventually return them to their habitat with their instincts and abilities intact.


Release back to the wild is our ultimate goal for every patient and affirmation of hours of service and hard work by volunteers and staff. To be released, animals must pass final examinations, and must be able to successfully forage for fish. All patients receive a flipper tag; some that are released may receive satellite or radio tags so their progress can be tracked if they are re-sighted.

The overall survival rate of animals admitted to the Center is just over 50% -- a positive statistic considering we rescue and admit very sick animals.

We study marine mammal health, collaborate with researchers around the world, and publish findings in peer-reviewed scientific journals. By doing so, The Marine Mammal Center contributes to the understanding of the state of our greatest resource – the oceans.Our scientific research program unites veterinary clinicians, pathologists, rehabilitation specialists, wildlife biologists, and research scientists to identify causes of marine mammal strandings and investigate health issues in our patients.

Our findings add to our knowledge of the health of marine mammals, lead to the development of new diagnostic tests and clinical techniques, determine the efficacy of rehabilitation, and reveal the effects of human and other stressors on the marine environment.

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:

How can you describe how the sea lions get used to humans once they have been rescued?

What did the author say about the amount of animals they rescue each year?

What are the pros and cons of rescuing the sea lions?

Why do you think it's good or bad? Explaine.

What would you do if you couldn't return a sea lion to its home?

What would you suggest they do with the sea lions they cannot return to the wild?


Feeding the sea lions help the sea lions become more comfortable with humans.

They rescue about six hundred each year.

The pros are that they can help the sea lions return to the wild and save the animals life. But some animals may suffer from shock or be unable to go back into the wild and will have to be taken care of for the rest of their lives.

I think it's good that they are saving them but the ones that have to live in captivity for the rest of their lives cost money and they have to be taken care of.

If I had to keep a sea lion I'd prolly try to fully tame him or her and teach them to do cool tricks and such it would be like having a dog but different.

They should just build them homes that make them feel like they are back in ht weird and give them other sea lions to play with so that they are not lonely or anything.
