Yolk formation in Isohypsibius (Eutardigrada)

Zoomorphology, 1987
In Isohypsibius granulifer, yolk is autosynthesized. The Golgi apparatus is mainly responsible for the formation of yolk, which consists of irregular platelets with heterogeneous contents and a diameter of about 1 μm. Dense globules, 300 nm in diameter, are visible among yolk platelets.

Form and function of the feeding apparatus in Eutardigrada (Tardigrada)

Zoomorphology, 2012
Tardigrade feeding apparatus is a complex structure with considerable taxonomic significance that can be schematically divided into four parts: buccal ring, buccal tube, stylet system, and pharynx. We analyzed the fine morphology and the tridimensional organization of the tardigrade buccal–pharyngeal apparatus in order to clarify the relationships ...

Myoanatomy of the marine tardigrade Halobiotus crispae (Eutardigrada: Hypsibiidae)

Journal of Morphology, 2009
AbstractThe muscular architecture of Halobiotus crispae (Eutardigrada: Hypsibiidae) was examined by means of fluorescent‐coupled phalloidin in combination with confocal laser scanning microscopy and computer‐aided three‐dimensional reconstruction, in addition to light microscopy (Nomarski), scanning electron microscopy, and transmission electron ...

Spermatozoon Ultrastructure in Two Species of Amphibolus (Eutardigrada, Eohypsibiidae)

Acta Zoologica, 1995
AbstractWe examined the ultrastructure of the spermatozoa from two species of eutardigrades, gonochoristic Amphibolus volubilis and hermaphroditic A. weglarskae, by scanning and transmission electron microscopy. The gametes from the two species were morphologically quite similar, each consisting of a short head, neck and tail. The head included a conic,

Milnesium guanyinensis sp. nov. (Eutardigrada: Apochela) from Yunnan, China

Zootaxa, 2023
A new species from China, Milnesium guanyinensis sp. nov. (Tardigrada: Eutardigrada: Apochela: Milnesiidae), is described by means of classical taxonomic analysis, i.e. morphology-based evidence, specifically obtained from light and scanning electron microscopy imaging.

New taxonomic position of several Macrobiotus species  (Eutardigrada: Macrobiotidae)

Zootaxa, 2007
The main character distinguishing Minibiotus from Macrobiotus is the presence of peribuccal papulae instead of lamellae. However, most Minibiotus species also share a set of characters of the bucco-pharyngeal apparatus. This set is defined by ten morphological features (the first seven common to all species, the last three to most of them): antero ...

Photokinesis of Macrobiotus hufelandi (Tardigrada, Eutardigrada)

Zoologischer Anzeiger - A Journal of Comparative Zoology, 2001
Abstract Macrobiotus hufelandi Schultze, 1834 was tested for response to light. Size groups of less than 120 m and of 120 m or more were used. It was found that the smaller, younger size group exhibited a statistically significant negative response to light.

Hebesuncus mollispinus (Eutardigrada, Hypsibiidae), a new species from maritime Antarctica

Zootaxa, 2012
A new species of eutardigrade, Hebesuncus mollispinus sp. nov. is described from Charcot Island, maritime Antarctica.The three known species of Hebesuncus are either widespread with questionable reports from the Antarctic (H.conjungens) or endemic to maritime and continental Antarctica (H. ryani and H. schusteri). Hebesuncus mollispinus sp.nov. differs

Head sensory organs of Halobiotus stenostomus (Eutardigrada, Hypsibiidae)

Biology Bulletin, 2012
The structure and arrangement of sensory organs in the tardigrade Halobiotus stenostomus (Richters 1908) have been studied using transmission and scanning electron microscopy techniques. The sensory organs found on the head of H. stenostomus are as follows: the circumoral sensory field, cephalic papillae, anterolateral and posterolateral sensory fields,
