Update on extracting polydorids

Hi annelid people

Thanks again to those who provided useful information and suggestions on
extracting polydorids (and other polychaetes) from coralline algae.  I
have passed on all these suggestions to the student involved in the
project.  I had 2 jars to play with myself, each containing lots of live
worms in holes in coralline alga-encrusted rocks in salt water.  I left
these in a refrigerator @4 degrees C over the weekend, and when I
remembered to look at them today I found that all the worms seemed dead,
but not yet too smelly.  I was able to gently pull many specimens from
their holes with forceps.  The specimens are seemingly in good condition
and either entire or nearly so.  If I had been more serious about this
and examined the samples only 1 day later I am sure I could have got
material in even better condition.  The specimens are now fixing in
formalin and I will soon have to no excuse for not looking at them!  I
don't know if this method has been selective; possibly some taxa have
remained invisible in their holes.  But my impression from seeing lots of
polydorids, cirratulids and syllids, plus a few other families in smaller
numbers, is that nearly everything has come out. 

Just thought that some of you may be interested in this result.
