Eutardigrada are tardigrada without lateral appendices. Primarily freshwater bound, some species have secondarily gained the ability to live in marine environments (Halobiotus). By cryptobiosis[?] many species are able to live in temporily very dry environments.

The order Apochaela consists of only one family, Milnesiidae[?], with of two genera: Milnesium[?] and Limmenius[?]. Milnesium tardigradum can be found worldwide and is one of the biggest species among tardigrades (up to 1.4 mm). The mouth of this predator has a wide opening, so the animal can eat rotifers and larger protists. The claws are characteristic. Other eutardigrades belong to the order Parachaela.
