He Does Know Musubi

I understand that in his book on his time in Hawaii, he has a passage regarding night fishing in Kailua Bay where he saw a fisherman catch

"a large fish, iridescent, and flopping at the end of one pole"

which he says his grandpa told him was a humuhumunukunukuapua'a.

Which does not say much for Gramps' knowledge of local fish as it is not a large fish, although some humu can be pretty big.  I'm guessing but either (a) the fisherman was pulling their leg or (b) the memory is inaccurate in part, and it was a different humuhumu (triggerfish) on the spear but its easy to remember humuhumunukunukuapua'a.  Who knows, it may have been a humuhumuhi'ukole or humuhumuumaumalei, neither of which are as "catchy" as their cousin humu.
