Can you milk a whale?
It would be hazardous to try milking any cetacean in the wild (although scientists have done so with recently deceased specimens). In captivity, though, the animals can be trained to tolerate it. Noren recently conducted a study that required 15 months of regularly milking two killer whale mothers at SeaWorld.

What heart rate is fatal?
If your heart rate exceeds 185 beats per minute during exercise, it is dangerous for you. Your target heart rate zone is the range of heart rate that you should aim for if you want to become physically fit. It is calculated as 60 to 80 percent of your maximum heart rate.
Is a heart rate of 200 during exercise bad?
More oxygen is also going to the muscles. This means the heart beats fewer times per minute than it would in a nonathlete. However, an athlete’s heart rate may go up to 180 bpm to 200 bpm during exercise. Resting heart rates vary for everyone, including athletes.
