California surfer RJ LaMendola said he was surfing recently, when he was attacked at Oxnard State
Beach in Ventura County, California, by a "demonic" sea lion that bit
him and dragged him off his board, he wrote on Facebook. LaMendola
described the sea lion as "feral" and "almost demonic." The surfer was
struck that the mammal was "devoid of the curiosity or playfulness" he
usually associates with sea lions. "This
isn’t normal sea lion behavior -- it’s something darker, something
dangerous," he wrote, saying he won't be surfing again "anytime soon."
Marine researchers are saying that sea lions on
the California coast are displaying strange behavior, likely
due to a harmful algae bloom impacting the region. The
sea lions are likely being poisoned by domoic acid, a neurotoxin within
the algae blooms, which they ingest through the fish they eat,
according to marine experts. Ingesting domoic acid can cause amnesic
shellfish poisoning in humans and marine mammals, according to the Marine Mammal Care Center.
There
have been reports of the marine mammals acting aggressively in some
cases, and in others, they appear lethargic, Jeni Smith, rescue
supervisor at SeaWorld San Diego, told ABC San Diego affiliate KGTV.
Smith described one sea lion who appeared to be "star-gazing." "Some animals seem very, very sleepy, maybe right after having a seizure," Smith said. "They may be abnormally aggressive."
Harmful algal blooms occur when colonies of algae grow out of control
and produce toxic or harmful affects on people, according to the National Oceanic and Atmospheric Administration.
Some blooms produce toxins that can kill fish, mammals and birds. In
some cases, the algal blooms can cause illness or death in humans,
according to NOAA.
Researchers are now seeing multiple consecutive
years of harmful algal blooms, Dave Bader, chief operations and
education officer at the Marine Mammal Care Center in San Pedro, told
KGTV. The Marine Mammal Care Center has taken in nearly 150 sea lions since
February, Bader said. There have been reports of dolphins and seabirds
falling ill as well, and this event could be worse than the bloom that
occurred in 2023, which killed 1,000 sea lions, according to the marine
conservation group.

SeaWorld's Jeni Smith urged the public to do their part to create a better environment for marine life and prevent pollution. "Throwing
away their trash, not allowing anything toxic to go down the storm
drain, because everything goes back to the ocean," Smith said.
