Sharks close to shore are typically juveniles ranging from newborn to several years old. The young predators are generally more interested in stingrays than you.
Those close to shore, however, are typically juveniles ranging from newborn to several years old: “babies” or “toddler sharks,” as researchers Rex and James Anderson of Shark Lab refer to them.
That’s what the researchers saw last week, as they searched for sharks off Del Mar. Rex flew the drone in long transects off the coast, looking for sharks in the surf, while Anderson communicated with colleagues on the boat to alert them to any sightings. He returned it to the site, and scouted out the shark again, while the boat crew readied a fishing spear fitted with an acoustic tag. For the next 20 minutes, the boat and shark played a game of chase behind the surf line, with the animal veering away each time the crew approached. Surfers didn’t appear to notice the race taking place nearby, and almost certainly couldn’t see the shark deep below the surface.
Anecdotal sightings of white sharks have surged in recent years, and photo identification surveys have confirmed more sharks at Guadalupe Island, she said. In a recent paper on shark populations, she estimated there are about 3,000 white sharks in the Pacific Ocean off North America.
