Following Tebble and Chambers (1982) - Polychaetes from Scottish Waters,
part 1 Family Polynoidae. Royal Scottish Museum Studies, Edinburgh - to
identify specimen of Harmothoe, one has to look for bidentate or unidentate
chaetae. This works very well for larger animals. Younger animals, however,
only have a few bidentate chaetae, and one has to look very carefully to
find them. Does anyone know another (easier) way to identify the younger
specimen?
