Humans - after over a century of observation - are unable to answer with any certainty how/where/when the largest animal to ever live on this planet (the blue whale) mates, gives birth, what it's courtship routines are, etc. They can make measured guesses and reasonable assumptions, but they don't KNOW.
Blue whales aren't purposefully trying to keep secrets. I imagine the Vulcans might be better at it than a blue whale.
