Malibu, California — A rare hammerhead shark sighting near one of Southern California’s popular beaches has caught the attention of marine experts after a fisherman captured video of the unusual visitor swimming remarkably close to shore.
The shark was spotted Thursday afternoon from Malibu Pier, with video posted by the social media account @PIERMACKEREL showing the animal swimming approximately a football field away from the shoreline near Surfrider Beach.
The sighting is notable because hammerhead sharks are rarely seen this close to Southern California beaches.
Warmer Ocean Temperatures May Be Drawing Shark Closer
Nate Jaros, vice president of animal care for fish and invertebrates at the Aquarium of the Pacific, told KTLA 5 News that hammerheads occasionally enter Southern California waters when ocean temperatures become warmer.
The current El Niño conditions are contributing to warmer-than-usual ocean temperatures, which can allow subtropical marine species to move farther north than they normally would.
“It’s absolutely exciting when we see these rare visitors to our area,” Jaros said.
According to the species sighting tool iNaturalist, the last hammerhead reported this close to Southern California beaches occurred in 2015, adding to the significance of Thursday’s encounter.
Shark Was Unusually Close to Popular Surf Spot
The shark’s location was perhaps the most unusual part of the sighting.
Hammerheads are generally associated with deeper waters, where they search for the prey they typically consume. Jaros said previous Southern California sightings have more commonly occurred farther offshore, including in the mid-channel between the mainland and nearby islands.
“Hammerheads, most species in general, kind of like deeper waters based on prey that they hunt,” Jaros said. “They don’t come in so close to shore.”
He added that seeing one so close to Malibu Pier was “a little peculiar.” Based on previous sightings in Southern California, Jaros said the shark in the video was likely a smooth hammerhead.
Smooth Hammerheads Can Grow 13 Feet Long
The smooth hammerhead is a large predatory shark species capable of reaching approximately 13 feet in length, according to the Shark Research Institute.
Its diet includes bony fish, smaller sharks, skates and stingrays.
The unusual appearance comes as marine life across Southern California continues to respond to warmer ocean conditions. Stingrays, for example, have also been appearing more frequently in local waters, with lifeguard data showing the number of people struck by stingray barbs has doubled compared with last year.
Experts Say Beachgoers Shouldn’t Panic
Despite the shark’s proximity to a popular beach and surf area, experts say there is no reason for widespread alarm.
Jaros explained that hammerheads are not generally considered highly aggressive toward people unless provoked.
“There’s not necessarily a huge risk to beachgoers,” he said. “It’s rare for them to be so close, and they’re not overly aggressive unless provoked.”
Still, he recommended that people use caution whenever a shark is spotted near shore.
That means beachgoers should pay attention to lifeguard instructions, avoid entering the water where an active shark warning is in place and give marine wildlife plenty of space.
Rare Sightings Could Help Scientists Track Climate Changes
The Malibu sighting may also provide scientists with another useful piece of information about how changing ocean conditions are affecting marine habitats.
According to NOAA Fisheries, tracking hammerhead sharks during El Niño seasons can help researchers understand how their ranges and preferred habitats may shift as ocean temperatures continue warming.
For now, the hammerhead’s appearance near Malibu remains a fascinating and unusual encounter — one that highlights just how quickly changing ocean conditions can influence the animals found along Southern California’s coastline.
