Northern Elephant Seals Return to the Ocean; Seals to Depart from San Francisco Zoo on Wednesday, June 21

Share Article

Four malnourished elephant seals, rescued by The Marine Mammal Center, will be released back to the ocean on June 21. The pinnipeds have been recuperating at the San Francisco Zoo since June 1. They'll be taken to Point Reyes National Seashore to maximize their successful return to the wild.

The Marine Mammal Center on Wednesday, June 21 will return six young northern elephant seal pups to the ocean, four of which have been temporarily rehabilitating at the San Francisco Zoo. They will be released at Chimney Rock at Point Reyes National Seashore in Marin County. This last, important step of the rescued seals’ recovery and rehabilitation is part of a conservation partnership between the Zoo and The Center to support the return of orphaned seal pups to their ocean home.

What: Media are invited to come to the San Francisco Zoo on Wednesday, June 21 at 9:45 AM to witness a three-step process involving removing the four seal pups from the Zoo’s seal pool, weighing the pups, and loading the pups into a transportation vehicle for their trip to Point Reyes. Media are also invited to accompany the rescue vehicles out to Point Reyes to view the release. Maps to the exact release location will be provided that morning.

When: Wednesday, June 21 at 9:45 AM. The event should take up to one hour.

Where: Media are asked to come to the Service Gate Entrance of the Zoo, which is located on the Zoo’s southeast side at the end of Herbst Road.

“We’ve been monitoring these young elephant seals since their arrival at the Zoo and are pleased that they have gained the proper strength and weight they’ll need to forage and compete for food in the ocean,” said Deb Wickham, manager of animal husbandry at The Marine Mammal Center. “We are grateful to the zoo for allowing us to utilize their pool, which has really helped these young pinnipeds develop their motor skills for a quicker recovery.”

Bob Jenkins, director of animal care and conservation for the San Francisco Zoo, added, “It’s been a great pleasure to partner with The Marine Mammal Center. The seal pups seemed to thrive here, with each consuming some eight to ten pounds of fish each day. Our visitors enjoyed seeing these wonderful animals prior to their return to the ocean.”

Young northern elephant seals rescued by The Center due to malnutrition are treated for as long as it takes to get them to the proper weight and to get them to the stage of being able to eat fish on their own. The entire process -- from rescue to release -- takes approximately two to three months. The four seals being released on June 21 were first at The Center, where they learned how to eat fish on their own, passed a physical exam, and then delivered to the Zoo on June 1. The Zoo provided swimming and recuperation space for the young seals, allowing them to “fatten up” to achieve the proper weight needed to survive in the wild and to continue their muscular development and motor coordination needed for prolonged swimming.
