Epidermal sensory structures in polychaetes

Dear Thomas, Geoff and others,

These short cilia appear similar to those of sensory structures we described 
in the lugworm. We published a study (histological, SEM and TEM) on epidermal 
sensory papillae of Arenicola marina. Numerous ciliated sensory buds, 
comprising supporting cells and two types of primary sensory cells, are 
present in the caudal epidermis. This study was coupled with an experimental 
one that demonstrated that the tail of the lugworm is involved in the chemo- 
and mechanosensitivity of the water flow from the respiratory water current.  

For more details see:

A few reprints are still available
