Worms as food?!

Hello, polychaete huggers!
I'm a graduate student in the Department of Biology at the University
of South Florida in Tampa. I work in a lab that studies the functional
morphology and feeding kinematics of elasmobranchs (sharks, skates and
rays). My current research is on the feeding kinematics of the Lesser
Electric Ray Narcine brasililensis, which is found from North Carolina all
the way to South America.
In order to undertake a feeding study, we need a LIVE prey item of a
consistent size class (roughly 2-3" TL) that can be collected on a regular
basis. Digging for worms around here has proved fruitless and NO ONE
uses polychaetes for bait, so they aren't sold in this area.
As a result, we've resorted to shipping in Glycera from the northeast.
I have had some people say that Nereis virens might be easier to keep in
the lab - is this a bristle worm? I tried feeding a Nereis (perhaps a different
species? We got them from Carolina Biol. Supply) to the rays on one
occasion and they spit them out. If they aren't stinging, then maybe I will
Can any of you suggest (1) a different worm species that fits the
above criteria (and is EASY to get!) and/or (2) a reputable, cheap-as-
possible place that will ship live worms? Any suggestions you have at this
point would be appreciated.
Thanks for your time,
