Tardigrades are host to many microbial symbionts and parasites. In glacial environments, the bacterial genera Flavobacterium, Ferruginibacter, and Polaromonas are common in tardigrades' microbiomes. [6] Many tardigrades are predatory; Milnesium lagniappe includes other tardigrades such as Macrobiotus acadianus among its prey. [7]
In 2011, tardigrades went on the International Space Station STS-134, [22] showing that they could survive microgravity and cosmic radiation, [23] [24] and should be suitable model organisms. [25] [26] In 2019, a capsule containing tardigrades in a cryptobiotic state was on board the Israeli lunar lander Beresheet which crashed on the Moon. [27]

These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
Anhydrobiosis in the tardigrade Richtersius coronifer. Anhydrobiosis is the most studied form of cryptobiosis and occurs in situations of extreme desiccation.The term anhydrobiosis derives from the Greek for "life without water" and is most commonly used for the desiccation tolerance observed in certain invertebrate animals such as bdelloid rotifers, tardigrades, brine shrimp, nematodes, and ...
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.
For example, freshwater microfauna in Australia include rotifers, ostracods, copepods, and cladocerans. [4] Rotifers are filter feeders that are usually found in fresh water and water films. They consume a variety of things including bacteria, algae, plant cells, and organic material. [3] Tardigrades inhabit a variety of lichens and mosses.
Tardigrades have been shown to respond to different temperature changes at different developmental stages. Specifically, the younger the egg, the less likely it is to survive extreme environments. However, not too long after development, tardigrades demonstrate a remarkable ability to withstand these conditions.
