Simplified version of Ed Shenk's pattern; the twisted marabou body is a lot quicker to tie than spun/clipped rabbit hair and still makes for a meaty profile. Change colors to suit your needs.
hook - Mustad 79580 #6
thread - UTC 140 brown olive
underbody - lead-free wire .030
tail - marabou blood olive
body - butt ends of marabou, wrapped
pectoral fins - deer hair tips
head - deer hair clipped
Part 1
mash barb, wrap rear 2/3 of shank with lead-free wire
start thread and over-tie lead wraps; tie in marabou blood feather (shank length)
twist marabou butts
and wrap forward to cover lead wraps
clean and stack a CLUMP of deer hair
measure for length (tips extending to bend)
2 soft loops and pull firmly
release the hair and let it spin around shank; add another wrap or two, pack it back (I use my fingers) and move thread forward
clean another clump, trim tips (no need to stack), tie in and spin
