Description

10 Foot male White shark stranded off Pleasure Point in Santa Cruz, CA yesterday. The white shark appeared to be sick and stranded. Despite team effort to release it back into the water; it continuously showed up back at the shore break.
The shark did not recover. Arranging follow up recovery and formal lab necropsy, hopefully at local UCSC lab or CDFW or NOAA facility to determine causes. Speculations are that this shark, a sub adult male white shark has stranded due to a Carnobacteroum Infection documented to be killing related species of mako sharks, salmon sharks and thresher sharks (Lamnid/Lamniforms sharks)

Several strandings of dead and dying leopard sharks in basin near Berkeley CA potentially related to water quality. Recorded by Sean Van Sommerman, Pacific Shark Research Foundation.
"Location is Berkley Aquatic Park; by standers called in several dead or distressed sharks and volunteers responded. 3 dead sharks near shoreline on private property, others seen seemingly acting unusually and in unusual location, inside of the tide gates and in urban canals and storm basin. Leopard sharks. Possibly rays also but unable to document or be certain thus far."

Description

On May 29, 2015 Andy Falk reported;“At approximately 10:30am I was surfing near the point at Fort Cronkhite , San Francisco with one other guy. There were about a dozen other surfers just to the South of us on the next peak over. I spotted a fin about 75 yards outside the lineup. The water was 54 degrees, the air about the same, the surf conditions were 3 – 5 feet. I immediately paddled in past the other surfer who was on his way back to the lineup. He ignored me when I told him I had spotted a fin. Onshore I told another surfer I'd seen a fin and he said; 'it was probably a dolphin, we see them here all the time.' The shape of the fin was definitely not a dolphin or porpoise. It was not swimming in the arcing fashion of a dolphin or porpoise. There was no question based on the size and shape of the fin it was a Great White Shark.”
