Priapulids possess a radial symmetry that is remarkably reflected in both external morphology and internal anatomy. It results the appearance of 25-radial (a number divisible by five) summarized as combination nonaradial, octaradial, octaradial (9+8+8) symmetries scalids. The secondary considered an evolutionary adaptation to lifestyle within three-dimensional environment bottom sediment. eight anteriormost, or primary, scalids retain their particular position because innervation directly...
Taxonomic studies of the phylum Kinorhyncha follow a standardised structure, which is extremely useful in many aspects, such as making it easier to read and compare different species descriptions. Nevertheless, morphological measurements methods, essential for formal description species, may differ according authors. In present contribution, we propose method taking representing measurements, with aim obtaining comparable repeatable morphometric results. Additionally, an online repository...
A new species of echinoderid kinorhynch, Echinoderes sensibilis, is described and illustrated using light electron microscopy. The specimens were collected from masses the red algae Corallina pilulifera growing in intertidal pools Tanabe Bay, Honshu Island, Japan. Diagnostic characters E. sensibilis include presence middorsal spines on segments 6-10; lateral spines/tubules 4, 7-12; remarkable trapezium-like subventral fields minute cuticular hairs 5-12. positions numerous sensory spots,...
Abstract The Russian gastrotrich fauna is virtually unknown, particularly the marine fauna. In ocean, investigations have been restricted to White Sea, from where only three fully described species reported so far. this study we describe a new of Aspidiophorus found in sandy sample collected off Vladivostok (Peter Great Bay, Sea Japan). oculatus n. sp. first chaetonotid Russia and representative order Chaetonotida Japan. Specimens are characterized by body up 147.5 µm total length; enveloped...
Larvae of priapulids are characterized by radial symmetry evident from both external and internal characters the introvert lorica. The bilaterality appears as a result combination several symmetries: pentaradial teeth, octaradial primary scalids, 25-radial biradial neck, decaradial trunk. Internal radiality is exhibited musculature circumpharyngeal nerve ring. position ventral cord excretory elements. Externally, determined anal tubulus two shortened midventral rows scalids bordering cord....
Abstract According to COI DNA barcoding testing, the marine bivalve mollusc Mactra chinensis , which is native Asia-Pacific region, diverged into three species. These species were preliminary characterized as M. clade I, II and III. To find out whether it possible morphologically distinguish samples representing genetic clades, we examined color of shells structure spermatozoa. It was found that number detected coloration types exceeds In addition, shown individuals belonging same can have...
Abstract Introverts of Priapulus caudatus and P. tuberculatospinosus bear 25 rows scalids, as well 8 spines scattered papillae in the region circumoral lip. These, first ring pharyngeal teeth , are sensory organs. Although superficially they differ between species, all characterized by apical and/or subapical openings which located on tiny cuticular tubules. All organs contain cilia bearing bipolar receptor cells. The situated area beginning scalids ultrastructurally similar to scalids....
A new species of echinoderid kinorhynch, Echinoderes aureus, is described and illustrated using a differential interference contrast microscope with Nomarski optics. The kinorhynchs were collected from washings brown alga, Padina arborescens Holmes, growing in tide pools Tanabe Bay, Honshu Island, Japan. Diagnostic characters E. aureus are the presence middorsal spines on segments 6-10, lateral spines/tubules 4 7-12, pair remarkably large subcuticular scars subventral position segment 3, an...
