|General Biology Additional Information||The tube is attached to hard substrata at the base but in reef aggregations is often free for much of its length. Height above the substratum varies but in reefs individual tubes may reach up to 18 cm, while the reefs themsleves vary between 75 cm and 2 m in hieght (Holt et al., 1998).
Dense aggregations of Serpula vermicularis tubes occur in enclosed and sheltered locations. These dense settlements of larvae on adult tubes may indicate larval gregarity but Bosence (1979(b)) suggests that aggregations only occur in locations with larval retention and few other hard substrates available for larval settlement. In the open marine environment Serpula vermicularis is not normally gregarious.
