Species | Hydroides dirampha [WoRMS] | |
Authority | Mörch, 1863 | |
Family | Serpulidae | |
Order | Sabellida | |
Class | Polychaeta | |
Phylum | Annelida | |
Synonym (?) | Hydroides diramphus | |
Sub-species level (?) | Not entered |
Native origin (?) | Not entered Comments: Pantropical |
Life form / Life stage (?) |
|
Sociability / Life stage (?) |
|
Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Sexual References: Liu, T. X., Kinn-Gurzo, S., Chan, K. Y. K. 2020. Resilience of invasive tubeworm (Hydroides dirampha) to warming and salinity stress and its implications for biofouling community dynamics. Marine Biology, 167(10), 145. Comments: The sexes are separate, as in most serpulids. |
Developmental trait (?) | Planktotrophy Spawning Comments: The larvae are planktotrophic, and spend about 10-15 days in the plankton at 22⁰C, with development being slower at low food levels. In experiments, larvae from high food treatments had better survival when transferred to the field than those from low food treatments. |
Characteristic feeding method / Life stage (?) |
Comments: The serpulid polychaete H. dirampha feeds by extending its feathery gills, and trapping plankton in the water column, which are transported by cilia to the mouth. |
Mobility / Life stage (?) |
|
Salinity tolerance range (?) | Exact range: 20 - 40 References: Liu, T. X., Kinn-Gurzo, S., Chan, K. Y. K. 2020. Resilience of invasive tubeworm (Hydroides dirampha) to warming and salinity stress and its implications for biofouling community dynamics. Marine Biology, 167(10), 145. Comments: Contrary to the early embryos, the larvae of H. dirampha were capable of surviving, growing, and settling at reduced salinity even at the extreme 20 psu treatment. |
Habitat modifying ability potential (?) | Unknown Comments: Not available. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Unknown Comments: Not available. |
Known human health impact? | Not known Comments: Not available. |
Known economic impact? | Not known Comments: Not available. |
Known measurable environmental impact? | Not known Comments: Not available. |

Association with vessel vectors (?) | Biofouling References: Liu, T. X., Kinn-Gurzo, S., Chan, K. Y. K. 2020. Resilience of invasive tubeworm (Hydroides dirampha) to warming and salinity stress and its implications for biofouling community dynamics. Marine Biology, 167(10), 145. Comments: H. dirampha is a widespread fouling organism and has been reported on ships and buoys. |
