SAUSALITO — The Sausalito-based Marine Mammal Center is celebrating a milestone: the rescue and rehabilitation of its 10,000th and 10,001st sea lions.

The sea lions nicknamed Milestone and Zodiac Girl will be released into the ocean on a deserted Marin County beach on Thursday. They were found suffering from a potentially fatal bacterial infection along the shoreline in the Santa Cruz area in mid-July.

Veterinarians kept them in saltwater pens and gave them antibiotics and now say there are no signs of the infection in their blood.

In all, the San Francisco Chronicle reports ( that the nonprofit Marine Mammal Center has saved 16,000 mammals since it was established in 1975, including sea lions, elephant seals, sea otters and whales.
