Dear Josh,

I looked in a few books on blue whales, but unfortunately, I couldn't find
a measurement of the narrowest point in a blue whale's gullet.  However, a
local biologist claims that he heard it's quite narrow--about the diameter
of a grapefruit.  This makes sense, since the whale doesn't need a wide
gullet to swallow krill.  But note, though this may make sense, it also may
not be true.  At lot of science starts with guess work, until someone makes
a better guess.

Sorry I couldn't be of more help.
