Marine biologists are puzzled by the hundreds of leopard sharks washing up dead on the shores of San Francisco for the past seven weeks.
They wonder if it could be the sign of a major problem throughout the Pacific Ocean. As both scavengers and super-predators, sharks in general play a critical role in keeping the ocean’s ecosystem in balance.
Sharks eat fish that are the weakest and help maintain “prey species diversity” by keeping other predators in check. Scientists worry that any decline in shark populations may threaten fishery operations and also indicate deeper problems in the ecosystem.

Yep
Leaking nucular plant in Japan
It’s probably all the stuff leaking out of the nuclear plants from Japan, but you’ll never hear that in the media.
This is straight up Fukushima!This$#%&!@*has to be taken care of and quit being swept under the carpet because it will cripple Japan’s economy!Well too bad!Trump needs to step up and crack skulls over there!
Could be that you’ve polluted not only the air but the water too
In California there is a vapor emitted by democrats that permeates the air and destroys people’s common sense and morality and kills sharks.
if it san francisco it must be shark aids
shut the fuckashima up it not radiation….pelosi…watters and feinstien were she skinny dipping and the rot from the southern regions caused a toxic liberal film in the water….poor sharks
Sommeran offers a possible explanation for many of the dead sharks found in Redwood City. During low tide, the Redwood City tide gates are closed to prevent flooding during the rainy season. When the tide is low, leopard sharks swim into the shallow water to mate.
When those flood gates close, the sharks get trapped and exposed to storm water runoff, which contains what Van Sommeran calls ‘extra crud going into the watershed.’ The water inside the gates becomes stagnant and creates a toxic environment in which the shark cannot survive. When the tide gates are reopened, those rotting carcasses of dead sharks are released into the waters and then contaminate others.”
No love for sharks or alligators, I would not miss them at all.
