Now, before you leave, do you want to make a seal's day?




Early in the morning on February 11, 2015, a small California sea lion pup was found crossing a four-lane road in San Francisco. A National Park Ranger protected the pup until rescuers from the Center arrived and transported him to the hospital for care. The park ranger named the pup Percevero, meaning “to persevere” in Latin, a name quite apt for this pup who seemed determined to survive.

Percevero was extremely underweight, dehydrated, and suffering from pneumonia and parasites. He was started on tube feedings of fish mash before transitioning to eating whole fish. Medications were also added to feedings: antibiotics for his pneumonia and a de-wormer for his parasites.

After six weeks of care, Percevero had nearly doubled in size, gaining 23 pounds. On March 30, 2015, Percevero was given a clean bill of health and was released at Point Reyes National Seashore, along with six other young sea lions.
