Short-Lived Aggregations of Filograna/Salmacina Tube Worms in the Gulf of Oman

Dense aggregations of serpulid worms were encountered in the Daymaniyat Islands (Gulf of Oman) from 10 to 20 m depth, over the period January–March, 2021. The species responsible for these aggregations belongs to the Filograna/Salmacina-complex (Annelida: Serpulidae). This species has been present in the area and observed along the Oman coastline, but high-density aggregates like this have not been reported before. The most probable cause of the aggregations, supported by field observations and Aqua-MODIS satellite data, was natural eutrophication with a subsequent algal bloom linked to the local winter monsoon. This observation emphasises the importance of documenting biodiversity and dynamics of reef communities along the Oman coastline

Nocturnal predation of christmas tree worms by a batwing coral crab at Bonaire (Southern Caribbean)

Christmas tree worms (Serpulidae: Spirobranchus) occur in shallow parts of coral reefs, where they live as associates of a large number of stony coral species [...

Extension of the recorded host range of Caribbean Christmas tree worms (<i>Spirobranchus</i> spp.) with two Scleractinians, a Zoantharian, and an Ascidian

Caribbean Christmas tree worms (Annelida: Polychaeta: Serpulidae: Spirobranchus) are considered host generalists in their associations with anthozoan (Scleractinia) and hydrozoan (Millepora) stony corals [...

Following the Phoenician example : Western Mediterranean colonization by Spirobranchus cf. tetraceros (Annelida:Serpulidae)

A newly established population of the fouling polychaete Spirobranchus cf. tetraceros is reported from the western Mediterranean (Valencia Port). Despite previous intensive surveys, this is the first record for the taxon in the Iberian Peninsula. Molecular analyses revealed that S. cf. tetraceros from Valencia are genetically identical to specimens from Heraklion, Crete, but different from those collected in the Red Sea and S. tetraceros sensu stricto from the type locality in Australia. Mediterranean and Red Sea S. cf. tetraceros form a well-supported monophyletic clade but are clearly distinct from New South Wales specimens of S. tetraceros. Our new molecular evidence supports the hypothesis that S. tetraceros is not a global invader of Australian origin but rather a large species complex in need of a comprehensive worldwide revision. These results highlight the importance of integrative taxonomic research for species with reported global distributions because these taxa may include cryptic invaders. An illustrated morphological account of the Valencia and Heraklion specimens and a taxonomic key for Spirobranchus species in the Mediterranean Sea are provided

Fan worms (Annelida: Sabellidae) from Indonesia collected by the Snellius II Expedition (1984) with descriptions of three new species and tube microstructure

The Indonesian archipelago is one of the most diverse regions in the marine World. Many contributions on polychaete worms have been published since the Dutch Siboga Expedition to the Indonesian archipelago at the end of the 19th century. In this study, we examined specimens of Sabellidae Latreille, 1825 collected during the Snellius II Expedition (1984) to Indonesia, carried out by the Dutch Research Vessel (RV) “Tyro” and the Indonesian RV “Samudera”. The results include reports of Acromegalomma acrophthalmos, A. interruptum, A. sp., Bispira manicata, B. porifera, B. secusoluta, Branchiomma boholense, Notaulax pyrrohogaster, N. tenuitorques, N. sp. 3, Parasabella crassichaetae, Perkinsiana anodina, and Sabellastarte spectabilis. In addition, three new species are described: Acromegalomma sumbense sp. nov., Claviramus olivager sp. nov., and Notaulax montiporicola sp. nov., the latter in living coral (Montipora nodosa). Further, Sabella (Potamilla) polyophthalmos Grube is transferred to Pseudopotamilla. Additional histological accounts of B. porifera and tube microstructure of A. acrophthalmos, B. porifera, P. anodina, Pseudopotamilla polyophthalmos and Sabellastarte spectabilis are also included

Taxonomy of Serpulidae (Annelida, Polychaeta): The state of affairs

© 2009 Magnolia PressThe Serpulidae are a large group of sedentary polychaetes inhabiting calcareous tubes. The relationships within the group are poorly understood and taxonomy of the group is very confused which is a major obstacle to accessing their phylogeny. This review provides up-to-date information on the current state of taxonomy of Serpulidae sensu lato (not including Spirorbinae). The morphology of the group is reviewed with special reference to the features that can provide characters for future phylogenetic analyses. Scanning electron micrographs illustrate the structure of the chaetae and uncini. The list of 46—in our opinion valid—genera is accompanied by detailed generic diagnoses, species composition and distribution (checklist), and remarks on major taxonomic literature. A taxonomic key to the genera and a list of invalid genera with synonymy is also provided.Harry A. ten Hove and Elena K. Kupriyanov

Pomatoceros triqueter

Pomatoceros triqueter (Linnaeus, 1758) Type locality. Not precisely known, but North Atlantic. Not present in the Suez Canal, but see Spirobranchus tetraceros, below. On ecological grounds, it is inconceivable that Pomatoceros triqueter has replaced Spirobranchus tetraceros in the intertidal and splash zone around Alexandria, Egypt as recently reported by El-Rashidy et al. (2009), a finding that contradicts Abd-Elnaby (2005) [quoted by Ghobashy & Ghobashy (2005: 90–93); see Spirobranchus tetraceros, below]).Published as part of Ben-Eliahu, M.
