There is an increasing problem of sea-lions off the coast of California becoming epileptic as result of global warming.
It appears to be caused by domoic acid poisoning, which in the wrong circumstances builds up to dangerous levels in shellfish and other sea animals in the area.
Domoic acid can be released in large quantities during algae blooms, and due to global warming algae blooms are happening far more often.
Another animal this is prone to this problem are sea otters. Given the historical damage we did to the sea otter population, unfortunately lee6 could do substantial damage.
Scientists have found treatments that will allow them to deal with animals affected,however it may become necessary to find methods of making them affected instead as algae blooms will become more and more common as the temperature of the water’s increase.
