General Biology Additional InformationOwenia fusiformis can be up to 10 cm in length (Hayward & Ryland, 1990) and its tubes up to 30 cm in length (Rouse & Pleijel, 2001). Owenia fusiformis can suspension feed by ciliary filter feeding or in low water flow can deposit feed by bending their flexible tube over so that the feeding crown touches the sediment surface (Rouse & Pleijel, 2001). The maximum recorded density was 4660 individuals per m² but this fluctuated over each year with mortality and massive larval settlement (Menard et al., 1990).
