California's Central Coast beaches are littered with dead dolphins and sea lions this summer. A sick sea lion was roped off by rescue workers to prevent people from approaching. As of June 27, the update read, CIMWI has responded to over 500 live sea lions exhibiting signs of domoic acid and over 150 dead sea lions in Santa Barbara and Ventura counties. A warning message is written in sand to prevent people from approaching a sick sea lion on the beach. Katherine Tangalakis-LippertMortality rates with adult sea lions have been "significant," according to CIMWI, and animals are dying despite receiving treatment.
