Worm marking?

Dear All,

First of all thanks a lot for the many replies I got concerning my question 
regarding sensory structures in Nereidae. It seems that the consensus is 
that they are indeed a mixture between mechano- and chemoreceptors. 
However, it seems still to be an area where more research would be 

Anyway I have another question. I want to be able to tra ck the motion of 
individual segments during the locomotion of errant polychaetes. The 
obvious way seem to mark the segment with some kind of paint or other 
markers. However, so far I have tried regular paint and correction liquid 
(both of them probably harmful to the worm, but that will probably be 
difficult to find something that does not dissolve in water and is harmless), 
but both markers had disappeared once the worms recovered from the 
anaesthetisation (since I only want to mark one segment I think it is 
necessary to immobilise the worms first). Have any of you any positive 
experience with marking worms that live in marine or aquatic 

Thanks again,
