The list of tardigrade taxa up to a sub-generic level, with the type species of each genus and the numbers of lower taxa in each taxon (known in the end of June 2018) is here presented together with the main environments in which taxa were found. Each listed taxon is characterized by characters common to all lower taxa using predominantly most recent ...

New cases of hermaphroditism in tardigrades
International Journal of Invertebrate Reproduction and Development, 1986Summary Hermaphroditism has been thought to be limited to a narrow circle of species of a single genus. With the new or confirmed cases referred to in this paper, hemaphroditism is now known in four of the five families of eutardigrades, whereas it is unknown for heterotardigrades and particularly for marine species, from which eutardigrades presumably

Anhydrobiosis in tardigrades—The last decade
Journal of Insect Physiology, 2011The current state of knowledge about anhydrobiosis in tardigrades is presented. In response to adverse environmental conditions tardigrades arrest their metabolic activity and after complete dehydration enter the so-called "tun" state. In this ametabolic state they are able to tolerate exposure to various chemical and physical extremes.

Eucoelomata in which:- 1. The body is not clearly differentiated into regions, although there is some evidence of metamerism. 2. There is no definite head. 3. The gut is straight and the anus is terminal. 4. The nervous system consists of pre-oral ganglia joined by circum-oesophageal commissures to a double ...

Tardigrades of North America: Aquatic Tardigrades of Western Missouri, U.S.A.
Transactions of the Kansas Academy of Science, 2018Fresh water tardigrades are an under documented group in the United States. In the 80 years since the first aquatic tardigrade was reported, there have been only 106 records across only 19 states and more than half of the 29 species have been recorded only once.

Rearing Tardigrades: Results and Problems
Zoologischer Anzeiger - A Journal of Comparative Zoology, 2001Abstract We report our first results of attempts to rear four species of eutardigrades inhabiting different substrates, feeding on different kinds of food and characterized by different sexual conditions and modes of reproduction. Attempts were carried out to follow individual terrestrial carnivorous (Macrobiotus richtersi, M.
