Ohia.org reminds us that sharks are both scavengers and super -predators, who greatly assist in keeping the ocean’s ecosystem balanced. Sharks eat fish that are the “weakest, sick or dead,” and also “maintain prey species diversity” by keeping other predator species in check. A decline in shark populations not only threatens fishery operations, but can also indicate deeper problems within our ecosystem. This may be the case in the waters of the Pacific Ocean off the coast of San Francisco, where for more than seven weeks, hundreds of Leopard sharks have been found dying, or dead, as reported by the San Francisco Gate.

– CBC News: Something very odd is happening in Pacific; Sea creatures acting strangely, species turning up where rarely seen — Related to Fukushima crisis? — L.A. Lifeguard: Used to be 2 shark sightings a year, now it’s 2 a day (VIDEOS) (ENENews, Nov 27, 2013):
CBC News Vancouver at 6, Nov. 4, 2013: What’s going on in B.C.’s weird ocean waters? Scientists are just as puzzled as the rest of us […] There’s something very odd happening in the ocean and in the waters around B.C. — sea creatures are behaving strangely. And species are turning up where they are rarely seen. […] Extraordinary marine activity […] From California all the way to Alaska […] Others point to disasters like Japan’s tsunami that triggered a nuclear crisis, but no one knows for sure. […] the ecosystem is such an intricate web of combinations and permutations and relationships so any disturbance in one side of it can have bi ramifications all through it. Only monitoring and reporting, experts say, will tell us what’s going on. >> Watch the broadcast here

From the article:
The next leg of the long voyage was from Osaka to San Francisco and for most of that trip the desolation was tinged with nauseous horror and a degree of fear.
“After we left Japan, it felt as if the ocean itself was dead,” Macfadyen said.
“We hardly saw any living things. We saw one whale, sort of rolling helplessly on the surface with what looked like a big tumour on its head. It was pretty sickening.
“I’ve done a lot of miles on the ocean in my life and I’m used to seeing turtles, dolphins, sharks and big flurries of feeding birds. But this time, for 3000 nautical miles there was nothing alive to be seen.”
In place of the missing life was garbage in astounding volumes.
And something else. The boat’s vivid yellow paint job, never faded by sun or sea in years gone past, reacted with something in the water off Japan, losing its sheen in a strange and unprecedented way.
– The ocean is broken (The Herald, Oct 18, 2013):
IT was the silence that made this voyage different from all of those before it.
Not the absence of sound, exactly.
The wind still whipped the sails and whistled in the rigging. The waves still sloshed against the fibreglass hull.

A fisherman discovers a two-headed bull shark. CNN’s Brooke Baldwin has more.
Sharks are dying in San Francisco Bay, with volunteers having rescued and removed about a dozen dead and dying leopard sharks in small waterways in Redwood City over the past few days in what is rapidly becoming a common occurrence, an expert said.
Redwood City resident Catherine Greer and her 13-year-old son, Lorenzo, were the first to discover the dying sharks at a lagoon near Redwood Shores off Radio Road earlier this week.
Greer, an avid fisher, said what she saw upset her. “It looked like they were trying to beach themselves,” she said.

Pilot Steve Irwin was astonished after spotting a mass of more than 100,000 sharks swimming just 100 yards off Florida’s sandy beaches.
The long-time fisherman and marine technology expert was cruising 300ft above the clear waters in his helicopter on Sunday when he came across the astonishing scene.
The 50-year-old – who shares his name with the late Australian ‘Crocodile Hunter’ – whipped out his smartphone to capture the masses of deadly predators, which spanned a 20-mile stretch of water.
