Reproduction Preferences Additional InformationMost individuals have a lifespan of 3 to 5 years but there are records for 7 and even 9 year old individuals. Sabellaria alveolata reefs undergo cycles of development and decay over a period of a few years. Although individual reefs come and go - areas that are good for Sabellaria alveolata tend to remain so.

Spawning occurs each July but actual recruitment levels vary considerably from year to year. Larvae spend between 6 weeks and 6 months in the plankton.
