KRON, Apr 13, 2017 (emphasis added): A troubling trend – sharks and other marine life are washing up on Bay Area shorelines. First, it was Santa Cruz, and now, it’s the Peninsula… dead sharks were found washed up Thursday morning… Experts say similar reports are coming in every day, and it’s not clear why all the marine life is washing up… [T]he Pelagic Shark Foundation in Santa Cruz is pleading with Bay Area people to be alert on walks and report to them immediately.

KRON transcript, Apr 13, 2017: “There are a lot of small dead sharks that have been found, just today… it’s just not clear why all the marine life is washing up like this.”

Santa Cruz Sentinel, Apr 8, 2017: [Sean Van Sommeran, Pelagic Shark Research Foundation executive director] said there have been too many white-shark strandings this year throughout coastal Northern California… he is frustrated about the lack of help for stranded sharks. “There’s been over 100 dead this year in San Francisco, San Mateo, Oakland and Berkeley Aquatic Park… We get them all the time in the San Francisco Bay Area.”

California Department of Fish and Wildlife, Apr 14, 2017: The carcass of a young great white shark was recovered on April 8 near Pleasure Point in Santa Cruz… It died of multiple organ failure, with major lesions in the brain, liver and heart… Unidentified microorganisms were observed in the fluid surrounding the brain and heart. Additional testing is underway to attempt to identify these pathogenic organisms…

CBS San Francisco, Apr 11, 2017: Marine Biologist Giancarlo Thomae said a necropsy found an infection had damaged the shark’s brain and other organs. “The species of the bacteria that contributed to the shark’s death is unknown at this time… However, the brain did have many lesions. In additional to that the shark’s heart and liver also showed damage, so we can conclude that the immune system of the shark was also compromised.”… Die-offs of leopard sharks and other types have occurred in the San Francisco Bay in the last two years…

KXTV, Apr 14, 2017: Washed up Great White Shark died of organ failure… Biologists believe the shark died of multiple organ failure, with major lesions in the brain, liver and heart. Unknown microorganisms were also found and additional testing is being done.

NBC Bay Area, Apr 11, 2017: A pathogen that eventually caused brain lesions is the reason why a shark became stranded on a Santa Cruz beach and later died last weekend. Animal experts say the pathogen is unlike any kind of bacteria that has been seen in sharks before.

KSBW transcript, Apr 11, 2017: “They say it could be the same infection that’s killing mako sharks this year… but the question remains, why is the infection making its way through different shark species?” — Sean Van Sommeran, Pelagic Shark Research Foundation executive director: “Let’s see if we can exactly identify what appears to be a new type of brain infection — first of its kind, documented in a white shark like that.”

KSBW, Apr 11, 2017: Van Sommeran said the pathogen is unlike any kind of bacteria that has been noted in sharks before. “Necropsy results show severe necrotic brain lesions“…
