A neurotoxin is suspected to have caused the death of a sea lion. Domoic acid is the substance possibly responsible, and its surge may be linked to warmer waters. The Marine Mammal Center has noted this potential connection.

The sea lion's death occurred after it was seen having seizures. Further information about this incident is available from the source.

Details about the circumstances surrounding the sea lion's death are limited, but it is known that the animal died after experiencing seizures, and a neurotoxin is believed to be the likely cause.
