Considerations on the taxonomy of the Phylum Tardigrada.
Zootaxa, 2013An analysis of the taxonomy of the Tardigrada is offered, based on the latest checklist version. A total of 1167 species from 113 genera were counted, but marine species are misrepresented on account of being understudied. Moreover, many poor descriptions and synonyms remain in this constantly growing list.

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.

Encyclopedia of Inland Waters is a new 3-volume reference work, pulling together all the key information in one source from the leading publisher in the field. Inland aquatic habitats occur worldwide at all scales from marshes, swamps and temporary puddles, to ponds, lakes and inland seas and from streams and creeks to rolling rivers.

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.
