2022年2月15日 · Tardigrades are ubiquitous meiofauna that are especially renowned for their exceptional extremotolerance to various adverse environments, including pressure, temperature, and even ionizing radiation. This is achieved through a reversible halt of metabolism triggered by desiccation, a phenomenon called anhydrobiosis.
Current Status of the Tardigrada: Evolution and Ecology1
2002年7月1日 · The Tardigrada are bilaterally symmetrical micrometazoans with four pairs of lobopod legs terminating in claws or sucking disks. They occupy a diversity of niches in marine, freshwater, and terrestrial environments throughout the world. Some have a cosmopolitan distribution, while others are endemic. About 900 species have been described thus ...
Meiofauna: Biodiversity, Ecology, and Role in Ecosystems - MDPI
2023年6月21日 · Two new species of Tardigrada belonging to the genera Coronarctus and Moebjergarctus were found. The analysis of a large amount of material collected during four deep-sea expeditions indicates a patchy distribution of tardigrades in the deep waters of the northwestern part of the Pacific Ocean.

2021年10月27日 · One of those overlooked groups is the phylum Tardigrada: hydrophilous micrometazoans, normally 50–1200 µm in length, and closely related to arthropods and onychophorans. Tardigrades represent a convenient meiofaunal group for study.
Expanding the taxonomic catalog of Brazilian meiofauna ... - SciELO
2024年6月24日 · In an effort to compile information on the diversity and distribution of meiofauna in Brazil, several taxonomists with expertise in the meiofauna phyla Tardigrada, Gastrotricha, and Kinorhyncha have been continuously updating the Taxonomic Catalog of the Brazilian Fauna (in Portuguese: Catálogo Taxonômico da Fauna do Brasil - CTFB), an online ...
Phylum Tardigrada - ScienceDirect
2020年1月1日 · Tardigrades are xerophilous, hygrophilous, and hydrophilous micrometazoans categorized into two main classes (Eutardigrada and Heterotardigrada) with over 1,300 species described from terrestrial, freshwater, and marine habitats. Commonly called “water bears,” they must be surrounded by a film of water to be active.
