Orphaned at six weeks of age, Repo, a southern sea otter pup, was rescued from a beach in Morro Bay, San Luis Obispo County. Because sea otter pups nurse for six months to a year and learn many skills from their mothers, orphans are extremely vulnerable. Highly specialized care is required for sea otters, including an expensive diet of prawns, chopped clams, and whole squid. When Repo arrived at The Marine Mammal Center, our volunteers provided 24-hour care, bottle feeding him every three hours, monitoring swims, and helping Repo groom his thick, insulating fur. After six weeks at the Center, Repo was transferred to the Monterey Bay Aquarium to finish his rehabilitation with a surrogate sea otter mother. Once healthy, he was fitted with a radio transmitter and released back into the wild.
