Children at the Marin Country Day School in Corte Madera had an odd participant in their walk-a-thon Friday morning: "Astro," a Steller sea lion! The sea lion wandered onto the lower field bordering the bay and immediately drew the attention of students, parents, and teachers.
After several efforts to coax the sea lion back into the bay failed, a call was placed to the Marine Mammal Center (www.marinemammalcenter.org). Thanks to the numbered tag on the sea lion’s back, the Marine Mammal Center was able to quickly identify him as “Astro.”

Center spokesman Jim Oswald said Astro - abandoned by his mother off the San Mateo coast last June - apparently became accustomed to people during his rehabilitation and now will not be returned to the wild. "The problem is we got him as a young pup and he didn't know anything but humans," he said. "We had to bottle-feed him, but we tried to minimize contact. But he was still around humans." Now the mammal center will seek a home for Astro, possibly the Mystic Aquarium in Connecticut, which has accommodations for Steller sea lions, a threatened species.
Whatever the reason, Astro’s visit made for a Walkathon to remember and by the time the marine people arrived, Astro had completed a full lap of the walkathon course! The school is working to collect a donation for Astro's one lap and donate it to the mammal center.
Way to go Astro!
