From my readings I gather that polychates are typically covered with a
mucous coating and that some also live in mucous stabilized tubes in the
sediment. Do errant polychates leave behind a sediment trail while they
move through the sediment (say a layer of sand)? And if so, is there any
literature discussing this and about the longevity of the slime trails once
the worm has moved on? The question has relevance for observations in
bioturbated sandstones.
