North Coast Marine Mammal Center


On an average year, the Northcoast Marine Mammal Center rescues between 30 and 60 stranded marine mammals per year. The NMMC has rescued 732 marine mammals since 1988, and has rescued over 100 animals per year during 2009 and 2010. The most common patients at the Center have been California sea lions, which have accounted for 39% of all rescues between 1988 ‚Äď 2009. Pacific harbor seals have been the second most commonly rescued marine mammal and account for 35% of rescues, followed by Northern elephant seals (23%). Other species that the Center has rescued include Northern fur seals, Steller sea lions, and Guadalupe fur seals. Steller sea lions and Guadalupe fur seals are both listed as ‚ÄúThreatened‚ÄĚ under the Endangered Species Act (ESA) and Northern fur seals are designated as ‚ÄúDepleted‚ÄĚ under the Marine Mammal Protection Act.

Current Rescues

Elephant Seal “Weaners”

Over the last two weeks the Northcoast Marine Mammal Center has welcomed 15 Elephant Seal “weaners.” Weaners are Elephant Seals who have been ‘weaned’ from their mothers’ milk, still may not be familiar with how to catch fish or even know what fish are.

Weaner Elephant Seals currently in residence in the Center’s outdoors pens include:

Violet (Point Saint George rescue)
Jelly Bean
Andy Irons

(This article will be updated asap when complete information is available!)

Violet and Taco

We brought in two more Elephant Seal weaners yesterday. Violet is the one from Point St. George and Taco is the one from right in front of Battery Point Lighthouse, close to the Northcoast Marine Mammal Center (NMMC).

Taco is a big boy at around 110 lbs.

Winston & Walter

Winston and Walter were found in crescent City, CA. Winston came to us on the first of April, and Walter came to us on the second. They are both about four months old. They came in weighing 82 pounds and 78 pounds. They did not properly learn how to eat fish once they were weaned from there mothers at about a month old. They should each weigh somewhere between 150-250 pounds. Once they have gained enough weight and have learned to eat on their own they will be released back into the ocean.

Muddy — Harbor Pup

Muddy was was found on a beach just south of Eureka, table bluff I believe. Volunteers were up to their knees trying to get to the beach (hence the name). He was brought in because of maternal separation and prematurity. He still has his lanugo coat, meaning he was born premature. He weighed only 13.5# on intake, he should weigh in the low twenties by now. He had labored breathing and was lethargic on intake. He is approximately 7 days old.

Mr Muddy -- 27 March 2014

Whiskers — Sea Lion

Whiskers is about 150# and was rescued also on March 9th from the Chart Room. He is likely to have Leptospirosis, so he will continue to stay in quarantine until further notice. Last blood draw was on 03.26.2014 and still showed signs of elevated kidney and liver enzymes. He is starting Doxycycline treatment and will have labs repeated in 2 weeks to determine whether he has kicked the lepto or not. *REMEMBER lepto is transmissible to you and your pets!* He will likely stay at least another month.

Rangerette — Sea Lion

Rangerette is a little 30 pounder who was rescued from Trinidad with multiple dog bite abscesses. She has been treated with laser therapy and had a drain placed to facilitate healing. She is currently on antibiotics. She is still underweight, yet eating well; we are going to continue feeding her about 20% of her BW to get a good blubber layer on her to protect her from the elements. Because she is still so small, she is in condo and pen depending on the severity of the weather. We would like to tong feed her meals, but leave a few fish in a small pool for her to forage herself if she chooses.

Bell and Oso: Our Northern Fur Seals

Animal Names:¬†Bell and Oso (aka ‚ÄúClock‚ÄĚ)
Admit Date: Late Spring 2013
Admit Weight: Approximately 15 and 20 lbs
Current Weight: Bell 29.5 and Oso 39
Released Date: TBD
Progress Notes: 
Bell and Oso came to us through a series of Marine Mammal Center transfers. During the unprecedented herring die-off on the South and Central California coasts they were rescued. Bell has never developed her secondary layer of external fur. Consequently, reintroduction into the wild would result in her demise, but she has a larger future in store for her. The New England Aquarium (Find them at: ) will be adopting her in the near future. Oso is extremely vocal. His goat-like calls regularly alerting staff and visiting members of the public to the presence of a seagull, raven, or other event in he and Bells pen. They love to swim and groom themselves in their pools. The NMMC anticipates releasing Oso concurrently with Bells transfer to New England (thanks to FedEx and their expert handling capabilities!).
