General Biology Additional Information | Sociability
Lanice conchilega can be found as a solitary individual or in populations of several thousand per m2. Feeding Buhr & Winter (1977) suggested that Lanice conchilega is unlikely to be just a surface deposit feeder as the fringed ends of its tube form an extensive network meaning that detritus will be trapped in the fringe. They suggest that feeding method is density dependant. At low densities (several dozen individuals per m2) Lanice conchilega will preferentially deposit feed. At high densities (several thousand individuals per m2) competition at the sediment surface will force animals to adopt suspension feeding. |

Reproduction Preferences Additional Information | Reproduction
Adult Lanice conchilega were seen to release gametes over several hours in June 1991 (Ansell, 1995). Kuhl (1972) remarked that the larvae of Lanice conchilega occur from April to October. The larvae spend up to 60 days in the plankton, so that larvae could potentially disperse over a great distance, depending on the hydrographical regime. |
