Toxic Algae Causing Brain Damage in Sea Lions along California Coast

 

Brain scans reveal damage that leads to neurological and behavioral changes, including beach strandings

AnimalScan has assisted in determining the damage from a toxin produced by marine algae that is inflicting brain damage on sea lions along California’s coast.  The toxin is causing neurological and behavioral changes that can impair the sea lions’ ability to navigate in the science pdfsea and survive in the wild.  Brain scans performed on 30 California sea lions detected damage in the hippocampus, a brain structure associated with memory and spatial navigation, in animals naturally exposed to the toxin known as domoic acid.  A complete report has been recently published in the Ecotoxicology section of Science Magazine (16 Dec 2015).  Download the publication here: algal-toxin-impairs-sea-lion
