There's been a recent increase in the number of sea lions becoming sick along the California coast. Marine biologists say the cause is domoic acid, a neurotoxin found within algae blooms. Fish feed on those algae blooms, and sea lions who feed on those fish end up getting sick from the domoic acid in the fish they eat.

Toxic algae bloom is wreaking havoc on the Southern California coast, especially in local sea lions, causing seizures, stillbirths, even violence.
