Video shows great white shark eating unsuspecting mammal, just off Alcatraz Island

A new video has captured a moment wherein the great white shark ate the unsuspecting mammal just off Alcatraz Island. Earlier on October 12, the great white shark was first recorded attacking in the San Francisco Bay, upon what seemed to be a sea lion.

Director of the San Francisco-based shark conservation group Shark Stewards and research associate at the California Academy of Sciences, David McGuire said that such an event was highly unexpected in the San Francisco Bay and was the first known witnessed predation there.

The video was recorded in a security camera aboard a company Alcatraz Cruises-owned ship. It displayed the shark snagging the sea lion and breaching the water. It also showed how a pool of blood started spreading out in the water, and how the shark came back to the surface a number of times to eat the remaining chunks of flesh.

The bay has never recorded any shark-human incidents so far. McGuire said that the vulnerability of drowning while swimming in this region was 1 in 1,100, whereas dying from a shark attack was 1 in 3.75 million.

He added, "Speaking from the perspective of a surfer and routine swimmer in open water, my risk is highest, but I don't feel it is dangerous and will be swimming from Alcatraz [tomorrow] for fun. The shark in question is likely gone".

Researchers have tagged several great white sharks and have captured many of them entering waters of the bay in the past few years. For instance, in 2007 to 2008, five animals have ventured into the bay. But this is the first time ever that one attacking and feeding on a huge marine mammal has been recorded.
