Tube-building worm (Sabellaria alveolata) is a polychaete marine worm (annelid), four centimetres long, capable of producing biogenic structures (pseudo-reefs) formed by galleries of sand glued together by secretions, and which can reach volumes of several cubic metres, with colonies numbering from 15,000 to 60,000 individuals per square metre - It is an "engineering" species which elaborates and modifies its ecosystem and favours biodiversity
