Larry;
Did not notice any yellow on the fins ( or anywhere else for that matter) and if it
grunted I didn't hear it (I don't wear my hearing aid when I'm out on the water;-).
In looking through my id books, the closest I come is the greater amberjack. Still
it is a bit far north for them, Mass is about as cold as they'll tolerate. When I
get home 2nite I'll do an extensive search. I gotta tell you though, watching that
thing navigate around the bridge was awe inspiring. I thought it had rockets on! Also
it jumped twice. Paul H
