"SANTA BARBARA, Calif. — Sea lions are stranding themselves on a long stretch of the California coast and showing signs that they may have been poisoned by a bloom of harmful algae, experts said Thursday.
The Channel Islands Marine & Wildlife Institute said that since July 26, it has been inundated by daily reports of sick sea lions along 155 miles (249 kilometers) of shoreline in Santa Barbara and Ventura counties, northwest of Los Angeles.
The marine mammals are suffering from domoic acid, a neurotoxin that affects the brain and heart, the institute said in a statement. The poisoning event is largely affecting adult female California sea lions, it said.
The nonprofit said it had rescued 23 animals so far. Coastal Vandenberg Space Force Base released photos of sea lions being rescued from one of its beaches on July 29."
