Class | Polychaeta | |
Phylum | Annelida | |

Sub-species level (?) | Not entered |

Life form / Life stage (?) |
References (not structured): Kočí, T., Goedert, J. L., Buckeridge, J. S. 2022. Eocene tube-dwelling annelids (Polychaeta: Sedentaria) from the Black Hills, western Washington State: the first record of Neodexiospira from North America. PalZ, 96(4), pp. 631-653. |
Sociability / Life stage (?) |
|
Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Self-fertilization Sexual Comments: The worms are hermaphroditic, with male and female gonads. Fertilization occurs outside the body, but inside the tube, where the larvae are brooded in an opercular chamber. Self-fertilization can occur, but is rare. |
Developmental trait (?) | Lecithotrophy Comments: Larvae are lecithrophic and can settle and begin metamorphosis within 1-5 hours of hatching. |
Characteristic feeding method / Life stage (?) |
Comments: Spirorbinine polychaetes are filter-feeders, feeding on phytoplankton and other suspended particles. |
Mobility / Life stage (?) |

Comments: Larvae of N. brasiliensis tend to settle on vegetation, including red algae: Ceramium planum; brown algae: Fucus serratus, Sargassum muticum; green algae: Ulva lobata; and seagrasses Zostera marina, Zostera asiatica, Phyllospadix iwatensis. This worm also occurs on pontoons, mussel and snail shells (tube-dwelling). |
