How long do blue whales nurture their young?

That’s a really great question! I’ve heard that there are several reasons why this is hard to answer.  In fact, there are several different kinds of whales.  You could mean blue whales, humpback whales, or fin whales, and each has its own different reproductive and care practices.  This means that if I had to guess, I’d say it depends a lot on the species, or even more specifically, on which of the individual animals you’re talking about.  It would be helpful to specify which blue whale you’re referring to!

WHich ones are the largest whales?
user
Of the three whales that I mentioned, blue whales are the largest.  They grow to be about a hundred feet long and weigh about thirty tons.  Of the three, blue whales also make the loudest noise.

How long do they nurse their young?

Well, they nurse their young for quite some time.  As I mentioned before, it’s not really accurate to say that they “nurse” them, since they don’t have teats.  There are several different kinds of whales, and one of them is the blue whale.  This particular whale is the largest of all whales, and has the longest pregnancy.  We’re talking about animals that grow up to a hundred feet long and weigh thirty tons.  After birth, the baby whale will stay with its mother for two years, and it will nurse for about eighteen months of that time.  Of course this is just for one of the three whales I mentioned.  Which one are you referring to?
