Mysterious sharks surround man at La Jolla Shores

SAN DIEGO – A local diver captured his recent encounter with several seven-gill sharks, a species Marine researchers are trying to figure out.

Trystan Smodgrass dove 40-feet deep into the ocean near La Jolla Cove and took video and pictures of sharks swimming as close as 3 feet away from him.

“Just right over by the buoy,” said Smodgrass, “Suddenly, there were six or seven of them surrounding us.”

Marine researchers at UCSD said seven-gill shark sightings are becoming more common, especially this time of year, but they don’t know why.

“We know very little about the movement pattern of this species in southern California,” said Andy Nosal, researcher at Scripps Institution of Oceanography in La Jolla.

To learn more about the “mysterious” species, researchers have started tagging seven-gill sharks with acoustic transmitters.

“We’re actually going to get to learn a lot more about when they actually arrive and when they leave La Jolla every year,” said Nosal.

There have been virtually no reports of seven-gill shark attacks locally in recent years, but experts are reminding divers they can be dangerous.

“Because of the size, they get to be about 10-feet long, their mouths are very large with very sharp teeth. It’s not a species you want to touch. A lot of divers try to pet these animals, that’s a really bad idea.” Nosal said.

    Really? Researchers can’t figure out that these sharks have figured out a new food source? The seals at La Jolla Cove are attracting predators. Yet another reason we should return the Cove to its rightful owners – people.

    Um, DUH! City of San Diego and all of the "environmentalists" who are trying to turn the children's pool into a seal showcase NEED TO STOP. Seals are cute and awesome, but do we really need to manufacture a feeding ground to attract predators? Many of us enjoy the water. Contrary to what the crazy activists will have you believe, there are countless places for seals (which are not endangered) to thrive. Not to mention the public health threat that the defecating mammals are creating on our beautiful beaches. Every year the smell gets noticeably worse. Smell = an overabundance of bacteria, folks. I'm still trying to figure out who's benefiting by wanting to close off the beach for human use. Who's pockets are being lined and WHY? IF YOU CARE ABOUT SURFERS, SWIMMERS, DIVERS, KAYAKERS, DO NOT SUPPORT THE MAN-MADE SEAL ROOKERY.
