Toxic Algae Bloom in California Sparks Aggression in Sea Lions

Sea lions along the Southern California coast are biting people due to ingesting toxic algae that contains a neurotoxin called domoic acid. The algae blooms have caused hundreds of sea lions and dolphins to become sick, suffering from seizures, brain damage, dehydration, and muscle spasms. At least two dozen beachgoers have reported being bitten. Harmful algal blooms occur almost every year in California, but this summer's outbreak is the deadliest seen so far. Wildlife care centers are overcrowded, and some sea lions have been left on shores due to lack of space. The toxins can also pose health risks to humans, and precautions have been advised. Researchers hope to contain the contamination and prevent the spread of toxins to other parts of the Pacific Ocean.
