Some annelid larvae, as in the
Sabellidae, have a metatroch and food groove and capture and transport particles, but they lack a mouth and do not ingest particles (Pernet, 2003).
A remarkable new genus and species of fan work (Polychaeta:
Sabellidae: Sabellinae) associated with marine gastropods.
Of those polychaete families found, only adult stages of Amphinomidae,
Sabellidae, Spionidae and Syllidae were reported previously for this location (Dean 2009, 2012, 2017) (Table 2).

Among the 10 indicator taxa, unidentified
Sabellidae, Mediomastus sp., Synchelidium sp., Ampelisca sp., Nemertea, Phyllodoce sp., and Minuspio cirrifera were consistently abundant with high SIM/SD ratio (>5).
In addition to serpulids, one species of sabellid (Family
Sabellidae)--Glomerula piloseta--and a few species of cirratulids (Family Cirratulidae), build calcareous tubes (Vinn et al.
Las categorias de gremios traficos utilizadas fueron: a)consumidores de interfase (IF) que pueden mudar su alimentacion de filtracion a resuspension, compuestos por la familia Spionidae y Oweniidae; b) depositivoros superficiales (SDF), compuestos por las familias Capitellidae, Paraonidae, Ampharetidae entre otros; c)depositivoros subsuperfrciales (SSDF), que incluyen a los Maldanidae, Orbiniidae, Cossuridae entre otros; d) omnivoros depredadores (OP), que albergan alas familias Nereidae, Nephtyidae, Hesionidae, Glyceridae, Syllidae entre otros; y e) suspensivoros (SF), compuestos por la familia
Sabellidae, Serpulidae, Sabellariidae, entre otros.
