Multigene analysis of lophophorate and chaetognath phylogenetic relationships

Molecular Phylogenetics and Evolution, 2008
Maximum likelihood and Bayesian inference analyses of seven concatenated fragments of nuclear-encoded housekeeping genes indicate that Lophotrochozoa is monophyletic, i.e., the lophophorate groups Bryozoa, Brachiopoda and Phoronida are more closely related to molluscs and annelids than to Deuterostomia or Ecdysozoa.

TEM Analyses of Chaetognath Reproductive Organs

2014
Transmission electron microscopy (TEM) enables analysis of subcellular organization. It is especially useful for describing the diverse array of cell types in the gonads and embryos of marine invertebrates. Here, I describe methods for preserving and embedding the reproductive organs of marine arrow worms for TEM, including procedures for staining ...

Pigments of meso- and bathypelagic chaetognaths

Marine Biology, 1977
Pigments of the meso- and bathypelagic chaetognaths Sagitta macrocephala and Eukrohnia fowleri were studied by chromatographic analysis. Supplementary histological studies were also performed. Fat-soluble properties and absorption spectra of the chaetognath pigments indicated that all pigments were carotenoid, independent of chaetognath species or ...

Immunohistochemistry of chaetognath body wall muscles

Invertebrate Biology, 2003
Abstract. A light and electron immunohistochemical study was carried out on the body wall muscles of the chaetognath Sagitta friderici for the presence of a variety of contractile proteins (myosin, paramyosin, actin), regulatory proteins (tropomyosin, troponin), and structural proteins (α‐actinin, desmin, vimentin).

Chaetognaths in Boka Kotorska Bay

Studia marina, 2014
Temporal and spatial distribution of pelagic chaetognaths was studied at six stations in Boka Kotorska Bay from March 2009 to June 2010. This work present for the first time detailed information of the ecology of chaethognats in the specific ecosystem of Boka Kotorska Bay. Chaethognats were more numerous in Kotor Bay and Parasagitta setosa was dominant

Chaetognaths of the Arabian Sea

1973
During the IIOE (1959–1965) the Indian Ocean Biological Centre (IOBC) received 1927 Zooplankton samples, of which 1548 are standard ones (IOBC, 1969). Of these, 614 samples belong to the area extending from 10° S to 25° N lat. between 20° E and 80° E long. The chaetognaths identified from these 614 samples form the basis of the present study.

Parasitism and Diseases In Chaetognaths

1991
Abstract The early records of parasites from chaetognaths (reviewed by Hyman (1959) and Alvariiio (1965)) consist mainly of isolated descriptive observations. They include protozoans, nematodes, trematodes and cestodes. Dollfus (1960) catalogued all early records of digenetic trematodes from chaetognaths and attempted to classify them on
