To assess whether closely related host species harbour similar symbiotic communities, we studied two polychaetes, Chaetopterus sp. (n = 11) and Chaetopterus cf. appendiculatus (n = 83) living in soft sediments of Nhatrang Bay (South China Sea, Vietnam). The former harboured the porcellanid crabs Polyonyx cf. heok and Polyonyx sp., the pinnotherid crab Tetrias sp. and the tergipedid nudibranch.

Abstract. Volume: 20Start Page: End Page: 53 Publisher: Boston:Ginn & Co.,[] Year: OAI identifier: oai::part/ Cited by: Chaetopterus variopedatus has been studied for over a century in terms of its physiology, ecology and life history.

One focus of research is on its intrinsic bioluminescent emissions, which can be. The group currently comprises four accepted genera: Chaetopterus Cuvier, Spiochaetopterus Sars, Phyllochaetopterus Grube and Mesochaetopterus Potts, with 97 available species names.

We describe a long-unnamed Chaetopterus Cuvier, species from southern California, using a combination of DNA barcoding and detailed morphological investigation employing high-resolution X-ray microtomography (micro-CT).Chaetopterus dewysee sp.

nov. is not only one of the most dominant annelids in the benthic communities of the shallow end of the La Jolla submarine canyon, but also a.

The pinnotherid crab Pinnixa chaetopterana inhabits marine polychaete tubes (e.g., Amphitrite ornata and Chaetopterus variopedatus) along the Atlantic and Gulf of Mexico coasts of the United States.

This crab occurred in % of Amphitrite tubes in New Jersey. The polychaete Lepidametria commensalis was found in % of Amphitrite tubes, often (%) with the crab. In North Carolina, the. Chaetopterus variopedatus is a species of parchment worm, a marine polychaete in the family is found worldwide.

However, recent discoveries from molecular phylogeny analysis show that Chaetopterus variopedatus sensu Hartman () is not a single species. Polychaetes, or marine bristle worms, have elongated bodies divided into many segments.

Chaetopterus variopedatus (Fig. 4) is widely distributed in the world, although a recent molecular phylogenetic analysis suggested its status as a species complex It is a filter feeder, living in a U‐shaped tube in the mud of marine shallow water, both ends of which stick out of the seafloor.

Material and methods. The chaetopterid from the Blake Ridge seep site was collected during Alvin dive (32°′ N, 76°′ W; m depth; cf., Van Dover et al. ).The tubes have length of at least 50 mm and have a maximum diameter of 2 mm.

Chaetopterids from the Gulf of California were collected from a mud volcano during the El Puma WAG cruise at 31°′ N, °5. Enders, H. A study of the life history and habits of Chaetopterus variopedatus. The egg of the polychaete Chætopterus, like many spiralian embryos, undergoes unequal cleavage during the first two cell divisions following fertilization.

The first cleavage gives rise to a large CD blastomere and a smaller AB blastomere. At second cleavage the CD blastomere divides asymmetrically, forming a large D blastomere and a smaller C blastomere while the AB cell divides to give rise.

We are interested in understanding whether the annelids and arthropods shared a common segmented ancestor and have approached this question by characterizing the expression pattern of the segment polarity gene engrailed (en) in a basal annelid, the polychaete have isolated an en gene, Ch-en, from a Chaetopterus cDNA library.

Genomic Southern blotting. Chaetopterus or the parchment worm or parchment tube worm is a genus of marine polychaete worm that lives in a tube it constructs in sediments or attaches to a rocky or coral reef substrate.

The common name arises from the parchment-like appearance of the tubes that house these worms. Parchment tube worms are filter feeders and spend their adult lives in their tubes, unless the tube is damaged.
