Toxic algae bloom is being blamed for sickening several California sea lions in Malibu, Calif., according to a nonprofit wildlife rehabilitation center.

Wildlife officials believe a toxic algae bloom is responsible for sickening several California sea lions in Malibu. The California Wildlife Center said over the weekend that it had received 14 calls in four days for sea lions in distress.

The animals appear to be suffering from exposure to a neurotoxin produced by algal blooms that accumulates in fish the sea lions eat.
