Molecular phylogeny of Arthrotardigrada (Tardigrada)
Molecular Phylogenetics and Evolution, 2010Tardigrades are microscopic ecdysozoans with a worldwide distribution covering marine, limnic and terrestrial habitats. They are regarded as a neglected phylum with regard to studies of their phylogeny. During the last decade molecular data have been included in the investigation of tardigrades.

El conocimiento de la fauna de tardígrados en la Argentina es restringido y amplias regiones se mantienen sin analizar. No hay registros en las provincias biogeográficas del Monte, Prepuneña, Puneña y Altoandina. La mayoría de los trabajos que son de carácter sistemático se han efectuado en las dos últimas décadas.

Hairybacks: Gastrotricha; Waterbears: Tardigrada
2013Hairybacks (Gastrotricha) (Figs. 45/1–2) are microscopic organisms up to 600 µm. These bilateral animals have elongated, wormlike body. Their body surface is covered with cilia arranged in longitudinal and transverse stripes. Despite their common name cilia are more frequent on the ventral surface than on the back.
