Gregarious Settlement by the Larvae of Hydroides dianthus (Polychaeta: Serpulidae) Academic Article uri icon

abstract

  • Larval development of the serpulid polychaete worm, Hydroides dianthus Verrill 1893 parallels that of other closely related species. The larvae prefer to settle upon surfaces already inhabited by other members of their own species rather than to colonize surfaces without such conspecific residents. However, very wide variations in the intensity of settlement are observed. These differences in the amount of settlement cannot presently be attributed to any single variable. Gregarious settlement appears to be typical for sessile species which do not have the ability to reproduce asexually after settlement.
