dollies are bucket mouths and their mouth is almost like a squawfish mouth but bigger and with a hell of alot more teeth while bull char's mouth is thinner and more like a regular trout/char mouth and i find the bulls have bigger shoulders while the dollies are just fat pigs all the way through

Trivia Question: Who can name off the top of their head the body of water in which the supposed Dollie/Bull Trout hybrids can be found.

Is this a trick question?  By some definitions ability to mix and produce fertile offspring would mean there is only one species.  I seem to recall Pitt lake or Pitt river tribs having overlapping spawning going on... kinky.

What about Ligers,Tigons and Grizzlars ? Oh My ! 

It's a Liger. It's Only like My Favorite Animal Ever.

So if Boise creak is the place of the supposed Hybrid, what is this (caught at the mouth of boise)?

Not sure what the first pic is, but the second one is a beek.

Hybrids tend to have characteristics that are overlapped by the two parents (ie. number of anal fin rays between anal fin ray numbers of DV and BT, jaw extension neither short or long). Interesting finding of DV/BT hyrbrids is the ability to produce offsprings, which most hybrids cannot do. Mykiss' colleagues are researchers in this field, so he can tell you all more about it (now he has to go find Taylor's papers and read and translate them for us ).
