They Also Have No Predators, And Great Whites Are A Protected Species.

Some Growing Challenges In Reasonable Plans In Commercial News Stories

"It extends from the upper torso area down to the pelvis," Sauri said. "A lot of these sharks spend most of their time literally 100 feet off the beach," said marine biologist Chris Lowe, who has been tracking the growing shark population off Southern California for more than a decade. In 2014, Lowe showed CBS News how his team is using underwater drones to follow and observe sharks. Shark attacks on both coasts are raising new concerns about beach safety this summer. New technologies like drones could make swimming less risky... He said the number of juvenile great white sharks in the area is rising significantly. They're drawn to warm water caused by El Nino and an abundance of fish to feed on. They also have no predators, and great whites are a protected species. "The questions that we're trying to answer now are, why are they at these beaches, how long do they stay at these beaches, what makes this beach so much more special than that beach?" Lowe said. According to Lowe, the six- to seven-foot-long juvenile great whites are skittish and usually stay away from swimmers. But with more sharks and more people in the water, "I think the rate of shark attack is going to continue to go up," Lowe said.
