For those of you hiding under a rock this week, a video has been making the rounds on the internet showing a great white shark attacking a seal right off Alcatraz Island in full view of tourists. The attack is being called the first shark ‘predation’ event in recent history in San Francisco Bay.

The original video of the attack went viral, racking up more than 800,000 views in just three days. But the original video didn’t start rolling until the shark had already started eating its meal. Now this new video has emerged captured from the Alcatraz Cruises ferry Hornblower Hybrid showing the attack from the beginning – including when the shark breached out of the water to latch onto its prey.

Scientists note that the great white sharks don’t make it into the bay often, but it’s not completely unheard of. This year in particular, possibly due to the El Niño, there has been noticeable uptick of great white sightings in and around Monterey Bay and off San Francisco, but so far nothing like this.

And below is the original viral video of the attack:
