Since I am attempting to learn more about the phylum Tardigrada, I thought I should share the paper that I found online which describes the nominate taxa for the class Heterotardigrada (Armored Tardigardes), Echiniscus testudo; it is called An integrative re-description of Echiniscus testudo (Doyère, 1840), the nominal taxon for the class Heterotardigrada (Ecdysozoa: Panarthropoda: Tardigrada). Also, I would appreciate any other papers or pertinent information on this topic.
Now I feel that iNaturalist needs a Tardigrade emoji.
