, 2022 Secondary structure of the 18S rRNA molecule of Chaetonotus (Hystricochaetonotus) mirabilis sp. nov. The single diagnostic molecular autapomorphy (red arrow) is situated in the terminal loop of helix 21es6c in the V4 region of the C domain. Note the long-range tertiary contacts between the V2 and V4 regions (highlighted in pink).

New data on Brazilian semiplanktonic gastrotrichs (Gastrotricha: Chaetonotida)
Zootaxa, 2022Gastrotricha are free-living aquatic microinvertebrates with a ubiquitous distribution. With almost two centuries of accumulated knowledge, currently there are more than 860 described species, but our knowledge on Brazilian Gastrotricha is still far from complete.

AbstractThe overall anatomy of Neodasys as well as data for hemoglobin‐containing cells are described. Hemoglobin‐containing cells are shown to be mesodermal specializations constituting approximately 14% of the animal's total body volume (4.87 ± 104 μl).

Heterolepidoderma caudosquamatum (Gastrotricha: Chaetonotida), a new species from brackish waters of Denmark [PDF]
Zootaxa, 2009 A new species of Gastrotricha Chaetonotida was found in Denmark: it is the first gastrotrich finding from Danish brackish waters. The diagnostic scales at the dorsal posterior end account for the proposed name Heterolepidoderma caudosquamatum. The morphological affinity of the new species with marine species of the genus supports its marine origin.

Hemoglobin-containing cells of Neodasys (gastrotricha, chaetonotida)—II. Respiratory significance
Comparative Biochemistry and Physiology Part A: Physiology, 1984Abstract 1. 1. The properties of the intracellular hemoglobin of Neodasys sp. are described and the utility of the hemoglobin in oxygen transport and storage is considered. 2. 2. The hemoglobin is located in immobile cells which occupy 14% of the total body volume. Heme concentration in these cells was 18.5 mM and the oxygen p50 (in vivo) was

Taxonomic and nomenclatural notes on freshwater Gastrotricha
, 2009Some taxonomic and nomenclatural remarks concerning freshwater species of Gastrotricha Chaetonotida are presented. In the family Chaetonotidae, the subgenus Chaetonotus (Hystricochaetonotus) is synonimized with the subgenus C. (Chaetonotus sensu stricto).

Many meiofaunal species are reported to be cosmopolitan, but due to uncertainties of identification, the affiliation of specimens from geographically distant areas to the same species-taxon is problematic. In this study, we examined morphological and molecular variation in samples of Xenotrichula intermedia Remane (Gastrotricha: Chaetonotida) from the ...
