LA JOLLA, Calif. (KGTV) — Imagine swimming when suddenly hundreds of fins start gliding through the water around you.Local beachgoers may be familiar with the sight, as shown in recently captured drone video in La Jolla. The video shows a mesmerizing view of the massive grouping of leopard sharks, about 4- to 5-foot long, swimming off the coast.Andrew Nosal, a professor and marine biologist at University of San Diego, recorded the video Monday — he also studied the sharks extensively for his dissertation at Scripps Institution of Oceanography.According to Nosal, the gathering, while perhaps intimidating to some, isn't all that rare.RELATED: Killer whale pod preys on dolphins off Southern California coast"Group formation ... is a common behavior for leopard sharks. In La Jolla, these leopard sharks are mostly (over 95%) mature pregnant females," Nosal said. "They appear to be attracted to this site because of its calm, warm water, which we hypothesize speeds up the rate of embryonic development."Leopard sharks give birth every spring after a 10- to 11-month gestation period.The sharks may also be attracted to food in the area, Nosal added, as they feed on squid, octopus, crabs, and small fish in nearby submarine canyons at night.RELATED: Dad captures son wakeboarding with dolphins off San Diego coastAnd while from above the sight of hundreds of sharks may alarm some, leopard sharks aren't considered threatening to humans as long as their space is respected."If a human grabs their tails, for example, the sharks may defend themselves by swinging around and biting the offender," Nosal said. "So, beachgoers should resist the temptation to touch or harass the sharks, which is a bad idea anyway, but also illegal because these sharks are inside a marine protected area."And if one is caught up in the swimming frenzy, there's no need to panic."...Enjoy the experience," Nosal said. "They will not bite unless grabbed. They are otherwise quite skittish and hard to approach. It is best to float still near the surface and allow the sharks to swim close." 2083

LA JOLLA, Calif. (KGTV) - On Wednesday, a team of researchers from the UC San Diego Scripps Institution of Oceanography will begin a 9-day exploration of the deepest parts of Southern California's coast.Sailing on the Exploration Vessel Nautilus, they'll use a Remote Operated Vehicle called "Hercules" to dive to the bottom of the ocean."Part of our mission is purely exploration," says Professor Lisa Levin, one of the researchers on the trip. "We're visiting places nobody's been to."The team will search 9 spots off the coast of Los Angeles and San Diego, located on an area of the Continental Slope called the "Borderlands." With various canyons, ridges, and seamounts, the depths range from 1,300 to 6,500 feet."We've selected sites that were dredged sometimes in the 1930s and 40s," says Levin. "Nobody's actually been down and looked with their own eyes, or with the aid of a camera to see what actually lives down there so that that's the exploration mode we're in."The researchers hope to collect samples of marine life and also minerals like phosphorus and manganese. They'll also look for bacteria in the sediment.Once collected, the team will study if any of it has potential for use by humans, either as medicine or other mineral-based purposes.The exploration will also help establish a baseline of what the ecosystem looks like now, so it can be protected in the future."We'll be looking at the microbes that live in sediments," says Levin. "To look at the potential of these microbes to produce chemicals that can cure cancer or provide aid in industrial processes. There's a variety of ways we humans might be able to use this."Part of the mission will also allow other people to take part in the exploration. The entire voyage will be live-streamed at www.nautiluslive.org and on YouTube and social media. Levin says this will help more people understand the importance of the ocean and their work."We believe very important to make the public aware of what's in the deep ocean and why it's important, why they should care about it, and there's no better way than allowing people to view it with their own eyes," she says. 2149
