I think in question 1, if we are talking about the type of whale, it is a sperm whale, rather than a white whale. Unless, of course, you are talking about the figure of speech 'white whale' which means an objective that is relentlessly or obsessively pursued but difficult to achieve.
Call it nitpicking and/or pedantry if you like. I do :)
