SAN DIEGO -- Last Friday, SeaWorld rescued a badly injured baby harbor seal from the Children's Pool in La Jolla.

Brenna Swiggum from SeaWorld is not exactly sure what caused the injury.

"I would say it was probably caused by a prop from a boat or possibly a shark attack," she said.

According to SeaWorld officials, the baby harbor seal is in very guarded condition with injuries indicative of a shark bite.

Richard Rosenblatt is a shark expert with Scripps Institution of Oceanography. He also suspects a shark attacked the seal.

"Certainly those animals are the natural prey of white sharks so you would suspect a white shark," Rosenblatt said.

Rosenblatt said there are plenty of sharks off the coast of San Diego, many of which are harmless and a few which are not.

"Mako sharks and blue sharks are the most common. Then you get a few white sharks," Rosenblatt said.

With only one natural predator -- the Orca -- and a movie called Jaws, just the mention of a great white shark can send shivers down one's spine.

Great white sharks are considered an endangered species. You can't take them out of the ocean but you can go see them in their natural habitat.

Lawrence Groth of Great White Adventures takes people on diving excursions to Guadalupe Island off the coast of Baja. He does not fear the sharks but he does respect them.

"Getting to spend time with them in the water and experience them up close and personal, people always leave with a greater respect for the whole ocean environment, not just the sharks," Groth said.

With summer just around the corner, many people will be heading to the water. Should San Diego beachgoers be worried about sharks?

"They should be more nervous about rip currents. They're much more dangerous than the sharks are," Rosenblatt warned.
