Richtersius is a monospecific genus of tardigrades in the family Richtersiidae; its sole species is Richtersius coronifer. [1] [2] [3] R. coronifer is one of two species of tardigrade that have been shown to survive and continue reproducing after exposure to outer space, specifically in the thermosphere at 258–281 km above sea level with ionizing solar and galactic cosmic radiation for 10 ...
Ramazzottius is a genus of water bear or moss piglet, a tardigrade in the class Eutardigrada, named after the Italian zoologist Giuseppe Ramazzotti.. Ramazzottius varieornatus (see image) is a terrestrial invertebrate that is extroardinarily tolerant of extreme conditions such as irradiation, chemicals, dehydration and high pressure. [2]
The tardigrade Dactylobiotus dispar can be trained by classical conditioning to curl up into the defensive 'tun' state in response to a blue light associated with a small electric shock, an aversive stimulus. This demonstrates that tardigrades are capable of learning.
Aerobius is a genus of extinct tardigrades ("water bears") of the superfamily Hypsibioidea. The genus contains a single species , A. dactylus , known from a single individual preserved in amber . The Aerobius holotype is preserved in the same piece of Late Cretaceous amber as Beorn , another extinct tardigrade.
Milnesium tardigradum can be found worldwide and is one of the biggest species among tardigrades (up to 1.4 mm); similar-looking species have been found in Cretaceous amber. [1] The mouth of this predator has a wide opening, so the animal can eat rotifers and larger protists. Other eutardigrades belong to the order Parachela.
Milnesium is a genus of tardigrades. [1] It is rather common, being found in a wide variety of habitats across the world. [2] It has a fossil record extending back to the Cretaceous, the oldest species found so far (M. swolenskyi) is known from Turonian stage deposits on the east coast of the United States. [3]
It can be cultured indefinitely and cryopreserved. [4] ... The Edinburgh Tardigrade project; NJ Tardigrade Survey; Tardigrades (English/German)
Milnesium alpigenum is a species of tardigrade that falls under the Tardigrada phylum.Like its taxonomic relatives it is an omnivorous predator that feeds on other small organisms, such as algae, rotifers, and nematodes. [1]
