Sabellaria alveolata

Sabellaria alveolata, a reef-building tube worm from European waters, also settled in response to conspecific tube sand. However, S. alveolata did not metamorphose normally in response to any FFA, and an inducer from the tube sand of these animals was not isolated or identified.84 These larvae were much less discriminating in their choice of substrata than were those of Phragmatopoma lapidosa californica. Larvae of the nongregarious species Sabellaria floridensis did not metamorphose to any greater extent on conspecific tube sand than on control sand. Metamorphosis was also not enhanced upon exposure to FFA.83...
