Eutardigrada are a class oftardigrades (Tardigrada) without lateral appendages. Primarily freshwater bound, some species have secondarily gained the ability to live in marine environments (Halobiotus). Bycryptobiosis many species are able to live temporarily in very dry environments. More than 700 species have been described.[2]
The orderApochela consists of only one family,Milnesiidae, with two genera:Milnesium andLimmenius.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 inCretaceousamber.[1] The mouth of thispredator has a wide opening, so the animal can eatrotifers and largerprotists. Other eutardigrades belong to the orderParachela.
