SV: [Annelida] strange worm

Hi Barbara,

It must be Barbidrilus (funny that your name is Barbara!), an odd genus of Enchytraeidae (Clitellata=Oligochaeta), with bifurcate anterior chaetae that are unique to this genus. The original species (Barbidrilus paucisetis) was described from Florida, but I think it was longer than 2 mm; perhaps your specimens are juveniles? Or it may be a second species?

The original reference can be found here:

Best wishes,

Hi All

Would anyone like to give an opinion on this worm?

A friend who is usually working with samples from freshwater benthics found a worm from the Ogeechee River, GA, that neither of us can ID. He doesn't have exact location info so it could be from a slightly estuarine environment. (The Ogechee flows directly into the Atlantic). It is mounted on a slide and the pictures are at 1000X for the first two images which are of the two ends of the worm and 40X on the whole worm (2mm or less length). He says the chaetae are only on one end of the worm in a cluster (looks like two clusters). There may be faint segmentation.
