SAN FRANCISCO (AP) - She's being called Olive, the miracle mom.
California researchers say they are amazed that a 4-year-old sea otter survived an oil tar soaking near Santa Cruz more than three years ago and went on to deliver a healthy pup.
The San Francisco Chronicle says Olive is the first sea otter to live through a dunking in oil and later become a mother.
The oil tar-covered otter washed up on Sunset State Beach in February 2009. Natural seepage was blamed.
Experts at the Marine Wildlife Veterinary Care and Research Center coated the otter with olive oil to loosen the tar and washed her with dish soap.
She was later outfitted with radio transmitter and released.
Last week, Olive was spotted atop a kelp forest with a pup on her belly.
