[Full text here: https://rdcu.be/bntId] At larval and adult stage of life cycle, sponges (Porifera) have different flagellated cells that play different roles in their body. The larval epithelium cells serve as locomotion organs, while adult collar cells (choanocytes) have a feeding function. Here, for the first time, we describe detailed structure...

Full text is available here: https://zookeys.pensoft.net/article/47460/ The Caspian Sea is a unique inland brackish waterbody inhabited by highly endemic fauna. This fauna consists of species of both marine and freshwater origin. Some Caspian invertebrates cannot be confidently referred to as animals of either origin. The endemic monophyletic fami...

[Full text here: https://rdcu.be/b7qrv] The kinetid (flagellar/ciliary apparatus) of eukaryotic cells is an important source of phylogenetic information. It was found to be a prospective morphological phylogenetic marker in sponges, since its arrangement in choanocytes is congruent with the topology of the phylogenetic trees. However, investigation...

FULL TEXT HERE: https://www.tandfonline.com/eprint/HPFBBKTNEI2DBNMNDA2Z/full?target=10.1080/14772000.2021.1958948 Freshwater sponges are widely distributed throughout the world, but their taxonomy and phylogenetics remain obscure. Studying distantly located specimens of the cosmopolitan spongillid Spongilla alba Carter, 1849 Carter, H. (1849). we...
Article
Full-text available
Diverse associations of freshwater sponges with molluscs were recently described from the Xingu River, Amazon Basin. However, such associations in other parts of the world are almost unknown. Here, we report on the discovery of epifaunal associations of a freshwater sponge (Corvospongilla, Spongillidae) with a byssus-attaching clam (Limnoperna, Myt...

The structure of the kinetid (flagellar or ciliary apparatus) is known to be of phylogenetic significance in sponges (Phylum Porifera) and can provide information about evolutionary relationships. Here, we report on the larval kinetid structure of two closely related species, Oscarella lobularis and O. tuberculata (Homoscleromorpha, Oscarellidae)....
Article
Full-text available
Homoscleromorpha is a recently recognized class within the phylum Porifera. While molecular analyses support monophyly of Homoscleromorpha, morphological data are largely lacking. Here, we investigate and comparatively analyze the detailed morphology of kinetids (flagellar apparatus) in choanocytes of ten Oscarella species. The kinetid is known to...
Article
Macroinvertebrates of stygobiotic origin contributing to benthic assemblages in springs of the two regions of West Transcaucasia were investigated. The regions concerned, basins of the Khosta­Kudeps­ ta Rivers (Krasnodarskiy krai) and Myussera Upland (Abkhazia), are well­studied and drastically different in a number of features. Frequency of occurr...
Article

Macrobioerosion is a common process in marine ecosystems. Many types of rock-boring organisms break down hard substrates, particularly carbonate rocks and calcareous structures such as dead corals and shells. In paleontology, the presence of rocks with boreholes and fossil macroboring assemblage members is one of the primary diagnostic features of...

Supplementary Information File: Supplementary Table 1. Hydrochemical characteristics of a water sample (no. 114W*) from the freshwater bioerosion site at the Kaladan River, western Myanmar. Supplementary Table 2. Mineral composition (%) of the rock substrate of the rock-boring bivalves from the Kaladan River. Supplementary Table 3. Chemical comp...

With the advent of molecular phylogenetics, the morphology-based classification of Porifera has been cardinally changed. However, the relationships between some clusters of Demospongiae, the most diverse sponge class, remain uncertain. An analysis of sponge cell ultrastructures, in particular the flagellar apparatus (kinetid) of choanocytes, may he...

The Great Lakes Depression is a large semi-arid region, whose freshwater invertebrate fauna is poorly known. Examining 37 waterbodies, we found freshwater sponges Eunapius fragilis and Spongilla lacustris (fragments) in the only one small river. Invertebrate species complex found on the sponges comprises nine species, their contribution to the asse...

Any discussion of the origin of Metazoa during the last 150 years and particularly in the recent years when the sister relationship of choanoflagellates and Metazoa was unambiguously shown by molecular phylogeny refers to the similarity of sponge choanocytes to choanoflagellates. These two types of collared radially symmetric cells are superficiall...
Article
Based on original material collected in the Caspian Sea, the harpacticoid fauna and its taxocene structure were described. The complied list of the Caspian harpacticoids includes 28 species of 16 genera and 10 families. Three species are new to science. Endemics make up 21% of the total species number, while cosmopolitans compose 36%. Four types of...

The complete re-description of Caucasian local endemic stygobitic atyid shrimp Troglocaris (Xiphocaridinella) jusbaschjani Birštein, 1948 is firstly presented after its original description given by Dr. Ya. A. Birštein (1948) under the name Troglocaris schmidti jusbaschjani. The species is still known exclusively from the type locality, hydrogen su...

Numerous specimens of poorly known pleustid amphipod Pleusymtes japonica (Gurjanova, 1938) (Crustacea: Amphipoda: Pleustidae: Pleusymtinae) were found in association with large hermit crab Pagurus ochotensis Brandt, 1851 (Crustacea: Decapoda: Paguridae) near Furugelma Island in the Sea of Japan. This is the first report of the species in associatio...
