Reproduction Details:

VARIABILITY RELATED: [Syllis spp.] Genus has species that reproduce by brooding with internal fertilization and direct development, in addition to species that brood with external fertilization and planktotrophic development (Wilson 1991) [Subfamily Syllinae] Stolonization (schizogamy). A part of the individual which becomes an epitokous sexual stage (stolon), which is massed with sexual products and usually has a special (stolonial) head. The stolon breaks away from the atokous benthic individual to lead a brief pelagic existence. Stolons are exclusively devoted to mating, which is followed by death. The unchanged benthic parent stock survives, regenerates the lost segments, and then reproduces again (Franke 1999) [Family Syllidae] Many species in the family reproduce asexually by transverse fission or by budding (Kozloff 1990)

Adult Mobility:

Actively mobile (Mobility is a normal part of at least part of the adult life cycle - at least in spurts. Not dependent upon distance traveled)

Adult Mobility Details:

Free-living; may live on surface or actively burrow. Movement is required for feeding (Macdonald et al. 2010)
