Kiotari, a female Pacific harbor seal pup, was rescued on May 1, 2010, from Ross Cove at Fitzgerald Marine Reserve in San Mateo. She had been separated from her mother shortly after birth. Kiotari was malnourished and suffering from flipper trauma and an umbilical infection. She was treated and released on July 24, 2010, at Point Reyes Marine Reserve, having gained over 10 kg. The spot patterns on a Pacific harbor seal are unique to a particular individual. Photo by Aaron J. Cohen for The Marine Mammal Center.
