Toxic Algal Bloom Off Southern California Threatens Marine Life and Public Safety

Over 140 sea lions and 50 dolphins have been affected by domoic acid poisoning, with aggressive behavior in sick animals raising safety concerns.

The ongoing toxic algal bloom in Southern California is one of the worst in recent memory, with experts fearing it may surpass the 2023 event that killed over 1,000 sea lions.
Wildlife rescue centers are overwhelmed, treating over 140 sea lions and nearly 50 dolphins since February, while many animals are found dead on beaches.
Symptoms of domoic acid poisoning in marine mammals include seizures, lethargy, 'stargazing,' and aggressive behavior, with one sick sea lion attacking a surfer in Ventura County.
The algal bloom, fueled by climate change and pollution, highlights the increasing frequency of harmful blooms, now occurring for the fourth consecutive year in the region.
Authorities urge the public to avoid approaching sick or distressed animals, as they may act unpredictably, and to report sightings to wildlife organizations.
