Abstract
Haploscoloplos elongatus in Bodega Harbor has an aggregated
dispersion ,pattern correlated with sediments of relatively large grain size
(0.149-0.42 mm). The association between algal cover and the presence of
worms is riot significant. The worm's soft, lobate proboscis is adequate for
direct-deposit feeding and is not involved in burrowing. The prostomium is
essential in formation of the penetration anchor and is used for enlargement
of the burrow. Movement through the substratum is by retrograde waves by
which the worm may move forward or backward.
