Amblyosyllis nigrolineata
Taxonomic Group: Annelids-Polychaetes


Amblyosyllis 'speciosa' is a Syllid polychaete in the subfamily Eusyllinae. Some individuals attributed to this species vary in color and other morphological features, so are likely part of a species complex. This taxonomic uncertainty makes determining a native range difficult. However, individuals introduced to the US West Coast resemble Imajima's (1966d) form 4, which is widely distributed on Japanese coasts. Specimens fitting this description are established in Southern California and are considered introduced. Individuals were found among coralline algae in rocky subtidal habitats and within benthic communities on pilings and dock floats. No impacts have been reported for this species.
