Communicating annelids

Hello folks,

I had a college student question the other day which left me struggling for a 
good easy answer. Do annelids communicate? Yes they do, else they 
wouldn't be able to procreate successfully and continue the lineage. The 
effect of sex pheromones, and chemical cues, right? In that sense is there 
any animal that doesn't 'communicate'? But what defines communication? I 
don't know what he had in mind, but maybe we can assume he was 
thinking of a narrower concept of  'face to face'  encounters in which 
information is exchanged both ways. Is that too restrictive for a lowly 

It might be interesting to talk about this. If you'd like to describe for the list 
any nice examples  of bidirectional or one-way communicating behaviour 
in annelids, or have views on the subject, I'd welcome your postings.

Looking forward to hearing from you,
