Tardigrades are one of the toughest creatures in nature! These tiny little animals, nicknamed ‘moss piglets’ or ‘water bears’, have incredible survival superpowers. They’ve been found in astonishing places, from the top of a mountain to the bottom of an ocean. They’ve even survived a trip into space!

Hermaphroditism in tardigrades
International Journal of Invertebrate Reproduction, 1979Evidence is presented to show the existence of hermaphroditism in tardigrades, a phenomenon hitherto unknown for this phylum: specimens were obtained containing male and female germ cells in maturation in the same gonad. Hermaphroditic animals have been found in a few species of Isohypsibius; in many species of other genera and also of Isohypsibius ...

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 ...

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 ...

On dormancy strategies in tardigrades
Journal of Insect Physiology, 2011In this review we analyze the dormancy strategies of metazoans inhabiting "hostile to life" habitats, which have a strong impact on their ecology and in particular on the traits of their life history. Tardigrades are here considered a model animal, being aquatic organisms colonizing terrestrial habitats.

Patterning on Living Tardigrades
Nano LettersMicro/nanofabrication techniques have revolutionized modern photonics and electronics. However, conventional methods remain incompatible with living organisms due to inherent constraints including nonconformal coating, radiation damage, and toxic solvent requirements.

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.

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.

Tardigrades have been reported from only 21 of the states in this country. This scarcity of published records is hardly indicative of the abundance of these animals. There are two good reasons for this lack of literature. First, unless one is working in rotifers, free-living nematodes, water-bears, or plankton and benthose, tradigrades probably won't ...

Two new tardigrade species from Sicily
Zootaxa, 2014Two new species of tardigrades are described from Sicilian moss samples: Macrobiotus insuetus sp. nov. and Diphascon (Diphascon) procerum sp. nov. Macrobiotus insuetus sp. nov. is a species of the harmsworthi-group characterized by both posterior and anterior claws of the hind legs, which are different in shape from those of the first three leg ...
