Hi all,
In a feeding study of Dipolydora commensalis (see reference below), I
removed the worms from their natural shell burrows and placed them in
glass capillary tubes. These worms (some isolated for over 100 days) were
found to deposit only a fine mucus layer in the glass tubes. These
observations add further evidence that D. commensalis forms the thin
calcareous layer by combining calcium carbonate crystals and mucus as
indicated by Jim Blake and Dan Dauer.
