"This has never happened in my 30 years," an on-site marine biologist said.
They’re not called killer whales for nothing.
This week, one particular pod of the majestic beasts has been on a murderous spree in Monterey Bay — attacking four fellow whales in just seven days.
“One thing that makes Monterey Bay unique is that gray whales and their calves have to cross the deep Submarine Canyon,” one boat captain said. “The canyon comes so close to shore, just off Moss Landing, that the calves have no place to hide. The orcas lay in wait for them.”
Though this happens every year, cool waters in Mexico forced the prey to migrate farther south this year. Which means a lot of very hungry killer whales were waiting for them when they finally arrived.
The most recent killing featured the same group of nine pouncing on a gray whale calf — right in front of an awe-struck (and probably a bit horrified) tour boat.
“This has never happened in my 30 years,” Nancy Black, a marine biologist who has studied the animals for decades, told SFGATE of the unprecedented incidents. “Just to witness that out in nature when you usually see that kind of thing on television is really spectacular.”
This calf-killing was caught on video and only took about 20 minutes:
A group of killer whales has hunted four gray whales in seven days in Monterey Bay. That's a rate Monterey Bay Whale Watch is calling unprecedented. Their latest kill was actually caught on camera (check it out about thirty seconds into the video).Read the full story: http://bit.ly/2oBVq06Video courtesy: Monterey Bay Whale Watch

“This was almost a record for how quick the killer whales attacked the mother and calf,” Black said — adding that hunts like this normally take anywhere from one to three hours, as the mother gray whale fights with her tale and protects the baby under her belly.
Some mamas are more successful than others. One “super mom” gray whale recently caught in drone footage single-handedly (fin-edly?) saving her calf from 12 killer whales:
Drone video from passenger Anoorag Saxena yesterday shows the Killer Whales leaving the Gray Whales alone after several intense attacks! The attack yesterday was the 6th attack in 11 days, and today on day 12 we have a report of the 7th attack in 12 days!!! The Killer Whales in this video, including Emma's group, have been invovled in all the attacks this year. Monterey Bay Whale Watch owner, captain, and lead Marine Biologist has been studying these Killer Whales for over 30 years and explained that only about 10-20% of Gray Whale calves that experience an attack like this survive, and often when they do survive it is because their mom helped them get closer to shore in shallow water. However because of the submarine canyon in Monterey Bay more Gray Whale attacks happen here than anywhere else in the world, and this year is already unprecedented! More to video and updates to come soon!

Along with the late migration of the gray whales, all of this whale watching excitement likely has something to do with the early arrival of the humpback whales.
Though they typically come to Monterey later in the spring, Black said there are already 60 to 70 humpbacks in the area — and they apparently enjoy messing with their smaller killer cousins.
“Humpbacks like to interfere with the killer whales for some strange reason,” Black explained. “They seem to want to protect the prey.”
This phenomenon was seen in one attack when a group of 40-foot humpbacks surrounded the feeding orcas, trumpeted loudly like elephants, and then chased the orcas away.
Black said she would expect the whales to be full by now, but they continue to eat.
“I expect they will become even more social in upcoming days as they (usually) do after stuffing themselves.”
