国家地理:Wild: Whale Attack 鲸鱼攻击

（单词翻译）

Then as we got closer, I could see what it was. It was a California gray whale cow.
The California gray whale is one of the largest animals on the planet. A fully-grown female known as a cow can easily weigh up to 35 tons, the equivalent of eleven female African elephants. The barnacles are clustered on the upper surface of this creature's head, positively¹ identified it.
And then when we got a little closer, somebody yelled. I think it was Heidi that first realized that there were gray whales in the area, which is what had attracted the killer² whales.
Gray whales and killer whales are not related. Orcas are in fact a type of dolphin. They are known as killer whales, not because they are whales, but because they are whale killers³.
This was the attack that I never wanted to see.
One organization, especially equipped to reveal the dark mysteries of Monterey Bay. Marine⁴ biologist George Matsumoto had heard of killer whale attacks on gray whales. But even he had never seen one.
Even here the research assumed that we'll spend 300 days a year on two different ships out there, we've never actually observed a killer whale attack from our vessels⁵.
Up until now, reports of orca attacks were the stuff of legend, rarely glimpsed, even by those who study these animals. But the Mother's Day encounter would provide scientists with detailed⁶ video evidence from almost start to finish.
10:15, 18 minutes after Turah had first sighted the orcas, she spotted⁷ another body in the water.
My goodness, you guy, look after the left side, look over there.
In the midst of the mayhem, there was another smaller participant.
And we are told by Heidi that there the orcas are attacking a gray whale and her baby.
Gray whales have only one infant at a time. Judging by the size of this calf⁸, it was around 3 months old.
It was nothing anyone could do. The passengers could only watch in horror and fascination⁹.
You don't really want to watch, but you have to, because you want to know what's going on.
No, your mother's gonna understand it.
Truly, this was one of the most powerful scenes any of us on board had ever seen.
The orcas are so tough...
The killer whales were thrashing their tails at it.
The killer whales were trying to prevent the calf from breathing - they were trying to drown it.
