The Pacific Marine Mammal Center in Laguna Beach last week rescued an elephant seal pup in Seal Beach, which SeaWorld had rehabilitated.
Melissa Sciacca, director of development and marketing at the center, said the incident wasn't cause for concern.
The seal, named Safari, was found weighing 92 pounds at 5 months old, and was described as lethargic, with feathers in his mouth. The center is investigating what caused Safari to become stranded. A tag designated the pup as coming from SeaWorld San Diego, according to Sciacca.
"It's important to establish first off that it's normal to get each other's animals," Sciacca said, noting that SeaWorld occasionally picks up seals rehabilitated at the center, which serves the Orange County coast.
Last month, the center also picked up a seal from SeaWorld named Yahoo due to an abscess that needed medical attention.
Sciacca insisted that the rescues are more likely due to normal stresses of the wild and that March through June is considered a busy season for pups to become stranded.
