WATCH: Orcas attack dolphins in Monterey Bay

A lone whale watcher in Monterey captured some amazing video while out on the water last week.

The experienced whale watcher at Sanctuary Cruises says eight Orcas were waiting to ambush a pod of about 1,000 dolphins.

Once the dolphins saw the Orcas, they made a mad rush to get out of the area.

It appeared at least one dolphin was killed by the Orcas.
