Sea lions sickened as toxic algae threatens California’s marine mammals

Number of animals affected by neurological toxin increases in past week as experts warn of impact from climate crisis

The number of marine mammals in California affected by a neurological toxin from algae has surged in the past week, in what could be another deadly year for animals such as sea lions, seals, dolphins and larger whales.

According to the Marine Mammal Care Center, a rescue facility based in Sausalito, California, the facility is treating more than 30 animals affected by a toxic algal bloom, with eight animals admitted on Wednesday. The algae bloom off the California coast has been on the rise in recent years, producing a neurological toxin called domoic acid.
