I recall reading that whale milk is extremely fatty (in the range of 50% fat) and would therefore probably be quite unpalatable to humans if drunk by the glass. Not, of course, that it would be particularly easy to milk a whale.

I would not normally choose to eat whale, either, but I note that missing from this discussion are the legal whale hunts and the consumption of whales by aboriginal peoples in North America. Many southern foods are prohibitively expensive, and native mammals, including whales, are considerably more nutritious than what is trucked/flown up from the south. Really, what's the greater affront to urban ethics -- eating whale, or eating a greasy, unhealthy $50 bucket of KFC that was probably made with factory-farmed pullets? I certainly won't turn down muktuk if I am offered some when I travel to some of the more remote northern communities this fall.
