(They aren’t always what they first appear to be)
In this photo by Ryan Murphy, the long thin, almost transparent ribbon, possibly a tentacle of a terebellid worm is shown along with a Pholus sp. gunnel and the siphons of a mollusc.
What we initially believed was a ribbon worm has been identified as a feeding tentacle!
We received this from Leslie Harris” I’m also pretty sure that the ribbon worm is really a terebellid feeding tentacle. There appears to be a groove running the length of the tentacle and packets of detritus being carried in the groove back to the mouth. ”
In the following image, the tangle of tentacles are also from one of the Terebellidae.
