The Marine Mammal Center
The Marine Mammal Center is a private, non-profit U.S. organization that was established in 1975 for the purpose of rescuing, rehabilitating, and releasing, marine mammals who are injured, ill, or abandoned. It was founded in Sausalito, California by Lloyd Smalley, Pat Arrigoni, and Paul Maxwell. It also serves as a center for environmental research and education regarding marine mammals, namely cetaceans (whales and dolphins) and pinnipeds (seals, fur seals, and sea lions). Marine mammal abandonment refers to maternal separation; pups that have been separated from their mother before weaning. At the Center, they receive specialized veterinary care; diagnosed, treated, rehabilitated, and ideally, released back into the wild. Animals in need of assistance are usually identified by a member of the public who has contacted the Center. These animals represent the following major species: California Sea Lion, Northern Elephant Seal, Pacific Harbor Seal, Northern Fur Seal, and the Southern Sea Otter. On a few occasions, the Marine Mammal Center has taken in Guadeloupe Fur Seals, Stellar Sea Lions, and Bottlenose/Pacific White-Sided Dolphins. The only non-mammals that the Center takes in are sea turtles.
